While various nanophotonic structures applicable to relatively thin\ncrystalline silicon-based solar cells were proposed to ensure effective light\nin-coupling and light trapping in the absorber, it is of great importance to\nevaluate their performance on the solar module level under realistic\nirradiation conditions. Here, we analyze the annual energy yield of relatively\nthin heterojunction (HJT) solar module architectures when optimized\nanti-reflective and light trapping titanium dioxide (TiO2) nanodisk square\narrays are applied on the front and rear cell interfaces. Our numerical study\nshows that upon reducing crystalline silicon (c-Si) wafer thickness, the\nrelative increase of the annual energy yield can go up to 11.0 %_\rel\nand 43.0 %_\rel for mono- and bifacial solar modules, respectively,\nwhen compared to the reference modules with flat optimized anti-reflective\ncoatings of HJT solar cells.\n
