  • This study aims to comprehensively calculate the conversion efficiency limits of multijunction solar cells having crystalline silicon (c-Si) not only as a growth substrate but as the lowermost active subcell as well. The first set of efficiency limits is calculated based on the detailed balance principle, assuming a stepwise absorption profile. Practical limits are then calculated using Si absorption data and Auger recombination parameters from the literature. The Si wafer thickness is also… CONTINUE READING
