The IV characteristics of previously found structure fragment with not optimized isotype hetero-barriers in the bottom connecting part of triple-junction GaInP/GaAs/Ge solar cell has been investigated. It has been shown that there are various ways to obtain the IV-curves of such fragment, including by creating structures containing only an isotype substrate and layers forming the barriers. It has been found that if hetero-barrier fragment contacts with the p-n junction layers, the shape of its reverse IV characteristic dramatically changes and depends on the incident light intensity.
