Abstract

Studies on MoO3 are reported to analyze its feasibility as a hole-selective front contact in diffusion free solar cells. The deposited layers passivate the silicon surface reasonably well, since surface recombination velocity of less than 20 cm/s was observed. The lifetime decreased after deposition of transparent conducting oxide and was regained by annealing at low temperature. The transmittance after TCO deposition is more than 80% in the visible region. The final solar cells fabricated using electron selective titanium dioxide film as the rear contact were 7.10% efficient.
