Abstract
The fabrication of low-cost n-Si/p-AgGaSe2 heterojunction solar cells by controlled thermal evaporation method is reported. It is observed that in the case of p-AgGaSe2 films deposited on H-terminated n-Si (H-Si) substrates at higher temperature of 650K, the photovoltaic properties of the n-Si/p-AgGaSe2 junctions are considerably improved. The improved junction, under solar simulator AM1 illumination, demonstrated an efficiency of ~5.2% on an active area of 0.18 cm2 without any antireflection coating whereas the AgGaSe2 films thermally evaporated at room temperature of 300K on H-Si substrates showed the efficiency ~2.1%.
