Perovskite Solar Cells
The 5 KW, state-of-the-art solar demonstration site at NASA Dryden is validating earthly use of solar cells developed for NASA's Helios solar-electric aircraft.
Adolph Spakowski, head of the Photovoltaic Fundamentals Section at the National Aeronautics and Space Administration (NASA) Lewis Research Center, illustrated the difference between conventional silicon solar cells (rear panel) and the new thin-film cells. The larger, flexible thin-film cells in the foreground were evaluated by Lewis energy conversion specialists for possible future space use. The conventional solar cells used on most spacecraft at the time were both delicate and heavy. For example, the Mariner IV spacecraft required 28,000 these solar cells for its flyby of Mars in 1964. NASA Lewis began investigating cadmium sulfide thin-film solar cells in 1961. The thin-film cells were made by heating semiconductor material until it evaporated. The vapor was then condensed onto an electricity-producing film only one-thousandth of an inch thick. The physical flexibility of the new thin-film cells allowed them to be furled, or rolled up, during launch. Spakowski led an 18-month test program at Lewis to investigate the application of cadmium sulfide semiconductors on a light metallized substrate. The new thin-film solar cells were tested in a space simulation chamber at a simulated altitude of 200 miles. Sunlight was recreated by a 5000-watt xenon light. Two dozen cells were exposed to 15 minutes of light followed by 15 minutes of darkness to test their durability in the constantly changing illumination of Earth orbit.
NASA Glenn's new LED solar simulator was developed by Angstrom Designs and UC Santa Barbara under a Small Business Innovative Research program to test the next generation of high-efficiency space solar cells for future missions. The new simulator contains over 1500 individually adjustable light sources, most of which emit light invisible to the human eye, to cover a 10 x10 foot area.
George Mazaris, works with an assistant to obtain the preliminary measurements of cadmium sulfide thin-film solar cells being tested in the Space Environmental Chamber at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Lewis’ Photovoltaic Fundamentals Section was investigating thin-film alternatives to the standard rigid and fragile solar cells. The cadmium sulfide semiconductors were placed in a light, metallized substrate that could be rolled or furled during launch. The main advantage of the thin-film solar cells was their reduced weight. Lewis researchers, however, were still working on improving the performance of the semiconductor. The new thin-film solar cells were tested in a space simulation chamber in the CW-6 test cell in the Engine Research Building. The chamber created a simulated altitude of 200 miles. Sunlight was simulated by a 5000-watt xenon light. Some two dozen cells were exposed to 15 minutes of light followed by 15 minutes of darkness to test their durability in the constantly changing illumination of Earth orbit. This photograph was taken for use in a NASA recruiting publication.
Researcher Susan Johnson and a mechanic examine a flat-plate solar collector in the Solar Simulator Cell in the High Temperature Composites Laboratory at the National Aeronautics and Space Administration (NASA) Lewis Research Center. The Solar Simulator Cell allowed the researchers to control the radiation levels, air temperature, airflow, and fluid flow. The flat-plate collector, seen in a horizontal position here, was directed at the solar simulator, seen above Johnson, during the tests. Lewis researchers were studying the efficiency of various flat- plate solar collector designs in the 1970s for temperature control systems in buildings. The collectors consisted of a cover material, absorber plate, and parallel flow configuration. The collector’s absorber material and coating, covers, honeycomb material, mirrors, vacuum, and tube attachment could all be modified. Johnson’s study analyzed 35 collectors. Johnson, a lifelong pilot, joined NASA Lewis in 1974. The flat-plate solar collectors, seen here, were her first research project. Johnson also investigated advanced heat engines for general aviation and evaluated variable geometry combustors and liners. Johnson earned the Cleveland Technical Society’s Technical Achievement Award in 1984.

Pilot Earle Boyer and researcher Henry Brandhorst prepare for a solar cell calibration flight in a Martin B-57B Canberra at the National Aeronautics and Space Administration (NASA) Lewis Research Center. Lewis was in the early stages of decades-long energy conversion and space power research effort. Brandhorst, a member of the Chemistry and Energy Conversion Division, led a team of Lewis researchers in a quest to develop new power sources to sustain spacecraft in orbit. Solar cells proved to be an important source of energy, but researchers discovered that their behavior varied at different atmospheric levels. Their standardization and calibration were critical. Brandhorst initiated a standardized way to calibrate solar cells in the early 1960s using the B-57B aircraft. The pilots would take the aircraft up into the troposphere and open the solar cell to the sunlight. The aircraft would steadily descend while instruments recorded how much energy was being captured by the solar cell. From this data, Brandhorst could determine the estimated power for a particular solar cell at any altitude. Pilot Earle Boyer joined NASA Lewis in October 1962. He had flown Convair F-102 Delta Dagger fighters in the Air Force and served briefly in the National Guard before joining the Langley Research Center. Boyer was only at Langley a few months before he transferred to Cleveland. He flew the B-57B, a Convair F-106 Delta Dart, Gulfstream G-1 with an experimental turboprop, Learjet and many other aircraft over the next 32 years at Lewis.

The Orion crew and service module stack for Artemis I was lifted out of the Final Assembly and Test (FAST) cell on November 11, 2019. The spacecraft has been stationed in the FAST cell since July for mating and closeout processing. The service module and crew module were moved separately into the cell, stacked and connected together for the mission. After lifting out of the cell, Orion will be attached to a tool called a verticator that rotates the stack from its vertical configuration to a horizontal configuration for transport to NASA’s Plum Brook Station in Sandusky, Ohio, where it will undergo full environmental testing to certify the complete vehicle for flight. Once the vehicle returns to Kennedy in several months, it will return to the FAST cell for installation of final panels left off for environmental testing purposes and the service module’s four solar arrays.

After lifting out of the cell, Orion will be attached to a tool called a verticator that rotates the stack from its vertical configuration to a horizontal configuration for transport to NASA’s Plum Brook Station in Sandusky, Ohio, where it will undergo full environmental testing to certify the complete vehicle for flight. Once the vehicle returns to Kennedy in several months, it will return to the FAST cell for installation of final panels left off for environmental testing purposes and the service module’s four solar arrays.

2010/107 - 04/17 at 21 :05 UTC. Open-cell and closed-cell clouds off Peru, Pacific Ocean Resembling a frosted window on a cold winter's day, this lacy pattern of marine clouds was captured off the coast of Peru in the Pacific Ocean by the MODIS on the Aqua satellite on April 19, 2010. The image reveals both open- and closed-cell cumulus cloud patterns. These cells, or parcels of air, often occur in roughly hexagonal arrays in a layer of fluid (the atmosphere often behaves like a fluid) that begins to "boil," or convect, due to heating at the base or cooling at the top of the layer. In "closed" cells warm air is rising in the center, and sinking around the edges, so clouds appear in cell centers, but evaporate around cell edges. This produces cloud formations like those that dominate the lower left. The reverse flow can also occur: air can sink in the center of the cell and rise at the edge. This process is called "open cell" convection, and clouds form at cell edges around open centers, which creates a lacy, hollow-looking pattern like the clouds in the upper right. Closed and open cell convection represent two stable atmospheric configurations — two sides of the convection coin. But what determines which path the "boiling" atmosphere will take? Apparently the process is highly chaotic, and there appears to be no way to predict whether convection will result in open or closed cells. Indeed, the atmosphere may sometimes flip between one mode and another in no predictable pattern.

The NanoRacks External Platform is a compact research platform fitted for versatile use on the exterior of the International Space Station (ISS).
This is a view of a solar cell blanket deployed on a water table during the Solar Array deployment test. The Hubble Space Telescope (HST) Solar Arrays provide power to the spacecraft. The arrays are mounted on opposite sides of the HST, on the forward shell of the Support Systems Module. Each array stands on a 4-foot mast that supports a retractable wing of solar panels 40-feet (12.1-meters) long and 8.2-feet (2.5-meters) wide, in full extension. The arrays rotate so that the solar cells face the Sun as much as possible to harness the Sun's energy. The Space Telescope Operations Control Center at the Goddard Space Center operates the array, extending the panels and maneuvering the spacecraft to focus maximum sunlight on the arrays. The purpose of the HST, the most complex and sensitive optical telescope ever made, is to study the cosmos from a low-Earth orbit. By placing the telescope in space, astronomers are able to collect data that is free of the Earth's atmosphere. The HST Solar Array was designed by the European Space Agency and built by British Aerospace. The Marshall Space Flight Center had overall responsibility for design, development, and construction of the HST.
The Pathfinder research aircraft's solar cell arrays are prominently displayed as it touches down on the bed of Rogers Dry Lake at the Dryden Flight Research Center, Edwards, California, following a test flight. The solar arrays covered more than 75 percent of Pathfinder's upper wing surface, and provided electricity to power its six electric motors, flight controls, communications links and a host of scientific sensors.

CAPE KENNEDY, Fla. -- At the Kennedy Space Center in Florida, one of Skylab 1's solar cell arrays is installed on the orbital space station in High Bay 2 of the Vehicle Assembly Building. Skylab 2 launch vehicle is in high bay 1, visible in the background. Each of the two solar cell arrays on the space station that will be deployed in orbit is designed to provide 10,500 watts of power. All power needed to operate the station and the Apollo Telescope mount will be taken from the arrays. Each array will have almost 1,177 square feet of surface area to turn sunlight into electrical power. Skylab 1 is schedule for launch April 30, 1973 and Skylab 2, carrying the astronauts Charles Conrad Jr., Dr. Joseph P. Kerwin and Paul J. Weitz to dock with the space station and enter it to live and work for 28 days, will be launched a day later. Photo Credit: NASA

This cutaway illustration shows the characteristics and basic elements of the Skylab Orbiter Workshop (OWS). The OWS was divided into two major compartments. The lower level provided crew accommodations for sleeping, food preparation and consumption, hygiene, waste processing and disposal, and performance of certain experiments. The upper level consisted of a large work area and housed water storage tanks, a food freezer, storage vaults for film, scientific airlocks, mobility and stability experiment equipment, and other experimental equipment. The compartment below the crew quarters was a container for liquid and solid waste and trash accumulated throughout the mission. A solar array, consisting of two wings covered on one side with solar cells, was mounted outside the workshop to generate electrical power to augment the power generated by another solar array mounted on the solar observatory. Thrusters were provided at one end of the workshop for short-term control of the attitude of the space station.
