摘要：
A heterojunction photovoltaic device comprises a chemically-doped n-type semiconductor layer, a charge-blocking layer that can have a compositionally graded configuration, and a chemically-doped p-type semiconductor layer. The charge-blocking layer can significantly reduce interfacial recombination of electrons and holes, increase open circuit voltage (Voc), and increase overall photovoltaic device efficiency.
