英文摘要：

The spectrum-splitting and beam-concentration diffractive optical element（ DOE） is a key component in a parallel solar cell system. In this paper, we simulate the DOE efficiency improvement through dispersion compensation. In the meanwhile,simulation results are verified by the geometrical phase equations.
