Optimizing Back Surface Field of Heterojunction Thin-Film Solar Cells by Numerical Simulation


Article Preview

A new structure of amorphous/ polycrystalline silicon heterojunction solar cells is reported. For a-Si (n+)/poly-Si (p)/poly-Si(p+) structure, the concentration, thickness, and the defect states of BSF are discussed. It is shown that the cell performance improves with thickness between 10-15nm, concentration is of the order of 1E19cm-3, the maximum efficiency up to 20.45%.
