Wave power poised to complement solar PV in future global energy mix
Wave power may emerge as a valuable renewable energy source given recent economic and technical projections indicating a substantial potential of wave energy, particularly in coastal and island regions. Wave and solar resources are complementary around the world and thus may lead to energy systems combining solar PV with wave power. Islands may benefit most from wave power added to solar PV.
First attempt to build lead-free perovskite-CIGS tandem solar cells
Indian researchers simulated a novel pairing of a CsGeI3 lead-free halide perovskite top cell with a copper-indium-gallium-selenide bottom cell. The resulting tandem device has the potential to achieve a power conversion efficiency of 26.06%
