Low-Intensity High-Temperature (LIHT) Solar Cells for Venus Atmosphere

Abstract

Low-intensity high-temperature solar cells that operate effectively in the atmosphere of Venus at various altitudes and also survive on the 465 °C surface of Venus are being developed. Thermal stability, high-temperature current–voltage ( <italic xmlns:mml="http://www.w3.org/1998/Math/MathML" xmlns:xlink="http://www.w3.org/1999/xlink">I–V</i> ), and external quantum efficiency measurements on GaInP/GaAs double-junction solar cells are presented. Solar-cell modeling under the atmospheric conditions of Venus is used to design the optimum solar-cell structure.
