Abstract

In this paper, a diffractive optical element(DOE) is designed as a spectrum splitting and concentrating element which is used in lateral multi-junction solar cells. The performance of the DOE by simulation indicates that optical efficiency over 80% can be achieved based on this design. The relationship between light concentration ratio and cell efficiency is researched. The results revealed that the cell efficiency increase with the light concentration ratio growing. It indicates that both the spectrum split and concentration realized by DOE is beneficial for the improvement of solar cell efficiency, which provide an important alternative approach to improve photovoltaic efficiency without the necessary need for epitaxial technology widely used in tandem solar cells, and would thus stimulate the research into high efficiency and low cost solar cells.
