Sobre lo que estabamos debatiendo el otro día..Mira los paneles solares de los O3B de SES...https://en.wikipedia.org/wiki/O3bThe satellites are powered by gallium arsenide solar arrays and lithium-ion batteries[50] and weigh approximately 700 kg (1,500 lb) each.Creo que estos son los más estandar en paneles solares espaciales...https://en.wikipedia.org/wiki/Solar_panels_on_spacecraftThe most efficient solar cells currently in production are now multi-junction photovoltaic cells. These use a combination of several layers of indium gallium phosphide, gallium arsenide and germanium to harvest more energy from the solar spectrum. Leading edge multi-junction cells are capable of exceeding 39.2% under non-concentrated AM1.5G illumination and 47.1% using concentrated AM1.5G illumination.[
