With expected qualification temperatures of around 160C and sun intensities of 2 suns, EnVision falls into the category of high temperature high intensity missions for the solar generator and as such require dedicated attention on solar array technology. For BepiColombo, detrimental effects on solar cell assembly level have been identified at elevated temperatures and under high UV exposure. Even if the EnVision environment is more benign than the BepiColombo one, in order to avoid unexpected anomalies and to benefit from the experience gained in BepiColombo, it is important to submit the current newest solar cell technology – the 4G32C-advanced solar cell from AZUR Space – and as a back up the 3G30 cell from AZUR to conditions representative of the expected EnVision environment. These tests could comprise e.g. a UV test campaign, temperature coefficient characteristion and a life test under representative conditions.
