Chinese Research Team Builds Molecular Bridge in Tandem Solar Cells: Indium-Free Composite Layer Breaks Efficiency and Stability Barriers for Next-Generation Photovoltaics

Researchers at Soochow University led by Professors Yang Xinbo and Zhang Xiaohong, in collaboration with Hong Kong Polytechnic University and multiple photovoltaic industry partners, have developed an indium-free composite layer material that creates a molecular bridge between perovskite and crystalline silicon layers in tandem solar cells. The breakthrough addresses two critical challenges facing perovskite-silicon tandem photovoltaics: charge …
