NASA Glenn researcher Tim Peshek shows off a new type of ultrathin solar cell, known as a ‘perovskite’ because of its structure. These solar cells show promise for space applications because of their high efficiency and radiation tolerance and open the door to extremely low cost and large solar arrays for spacecraft or lunar surface habitats.

Photovoltaic Hardware - Prototype Organic Solar Cell Module

National Aeronautics and Space Administration (NASA) Lewis Research Center. NASA signed an agreement with the Papago tribe in May 1978 to provide the village with solar-generated electricity within the year. The project was funded by the Department of Energy and managed by NASA Lewis. Lewis provided all of the equipment and technical assistance while the tribe’s construction team built the arrays and support equipment, seen here. The 3.5-kilowatt system was modest in scope, but resulted in the first solar electric village. The system provided power to operate a refrigerator, freezer, washing machine, and water pump for the village and lights in each of the 16 homes. The system was activated on December 16, 1978. During the next year officials from around the world travelled to Schuchuli to ascertain if the system was applicable to their areas. The major television networks and over 100 publications covered the story. Less than one percent of the cells failed during the first year of operation.

STS-117 astronauts and mission specialists Jim Reilly (center frame), and John “Danny” Olivas (bottom center), participated in the first Extra Vehicular Activity (EVA) as construction resumed on the International Space Station (ISS). Among other tasks, the two connected power, data, and cooling cables between trusses 1 (S1) and 3 (S3), released the launch restraints from and deployed the four solar array blanket boxes on S4, and released the cinches and winches holding the photovoltaic radiator on S4. The primary mission objective was the installment of the second and third starboard truss segments (S3 and S4).
