摘      要：In this paper,a novel method is proposed and employed to design a single diffractive optical element（DOE） for implementing spectrum-splitting and beam-concentration（SSBC） functions *** develop an optimization algorithm,through which the SSBC DOE can be optimized within an arbitrary thickness range according to the limitations of modern photolithography *** simulation results reveal that the designed SSBC DOE has a high optical focusing *** is expected that the designed SSBC DOE should have practical applications in high-efficiency solar cell systems.
