Characterization of the Protocrystalline Silicon Multilayer

摘要

Protocrystalline silicon (pc-Si:H) multilayer solar cell is very promising owing to its low degradation rate and fast annealing effects. But until now, the pc-Si:H multilayer absorbers have not been investigated in detail on its material characteristics. In this work, we investigate the structural characteristics of the pc-Si:H multilayer using transmission electron spectroscopy (TEM), Raman spectroscopy and Fourier transformed infra (FTIR) spectroscopy. The TEM micrograph shows that embedded crystalline-like objects (CLO) in amorphous silicon (a-Si:H) matrix. The excellent light-soaking behavior of the pc-Si:H multilayer is due to these CLO which improve the structural order in material.
