13.8% Efficiency Hybrid Si/Organic Heterojunction Solar Cells with MoO3Film as Antireflection and Inversion Induced Layer

High reflection and low build-in electrical field hinder the power conversion efficiency (PCE) of planar n-Si/organic solar cells. Depositing a thin layer of MoO3 can improve the performance by creating an antireflection layer on the front surface as well as inducing an inversion layer in the Si. The as-processed device achieves a record PCE of 13.8%.
