Missions close to the sun such as BepiColombo or Venus Express always require dedicated testing of solar cells since they operate under non-standard conditions, i.e., High Temperature High Intensity (HTHI). The next mission that falls into the category of HTHI ESA mission is EnVision to Venus, which – in case it will be adopted – is planned to launch in the early 2030s. The space solar cells destined for the PV solar generator are expected to operate at sun intensities of 2 suns and most probably in the temperature range of 130°C-140°C. At INTA-SPASOLAB the temperature coefficient of two cell candidates for the PV solar generator of the ESA EnVision mission, which are a quadruple junction and a triple junction solar cell, have already been determined at 1 sc-AM0 within the range from +25ºC to +100ºC.
