Importance of Nanocrystallites in a-Si:H Passivation Layer in Improving The Performance of Silicon Heterojunction Solar Cells

摘要

Correlation between surface passivation of crystalline silicon and the microstructure of silicon passivation layer has been investigated. Based on the optical constants determined by Spectroscopic Ellipsometry measurements, effective medium approximations has been employed to simulate the microstructure of silicon thin film with the mixed phase, including amorphous structure and spherical or ellipsoidal crystallites. A key factor f
