Investigation on AR Techniques of Silicon Solar Cells

Abstract:

This work presents study of both the antireflection coatings on silicon solar cells and surface texture of silicon solar cell, with the aim to prepare high quality Si solar cells. Surface texturing, either in combination with an anti-reflection coating or by itself, can be used to minimize reflection, but the large reflection loss can be reduced significantly via a suitable anti-reflecting coatings. Significant improvement of the short circuit current after anti-reflecting coatings was observed. It is found that the currentvoltage characteristic with a double-layer anti-reflecting coatings is better than that with a single-layer anti-reflecting coatings. Depositing a multilayer on the textured surface reduces the large reflection loss significantly. The short circuit current of silicon solar cells has significant improvement after depositing anti-reflecting coatings on textured surface silicon, and it increases the efficiency of the Si solar cells.
