This paper presents results on the simulation of photo converters in a spectral splitting system where solar radiation is separated into three spectral ranges (Δλ₁<500 nm, Δλ₂ = 500−725 nm and Δλ₃>725 nm) by means of dichroic filters and then converted to electrical energy by photoconverters based on InGaN/GaN, GaAs/AlGaAs single−junction heterostructures and monocrystalline silicon c−Si. Special attention is paid to the absorption spectrum spreading due to more efficient conversion of the ultraviolet part of the spectrum. The total efficiency of the system varies from 21% to 37% depending on the design of heterostructures.
