摘要: SnO2/n‐Si solar cells (area=1 and 4 cm2) having AM1 efficiencies of 12.3% on single‐crystal silicon 10.1% polycrystalline have been fabricated. The tin oxide is deposited by spraying a SnCl4 mixture onto heated substrates. Using this low‐cost process, large‐area (20‐cm2) 10% efficiency also made. smaller diffusion length higher resistivity in the (Wacker) accounts for its lower as compared to cells.
