Researchers from the Hong Kong Polytechnic University (PolyU) have developed a perovskite-organic tandem solar cell designed to withstand damage caused by negative voltage, or reverse-bias stress. The advancement addresses a key reliability challenge for thin-film photovoltaic technologies, which can experience reverse-bias conditions when partial shading from trees, buildings, or other obstacles creates electrical mismatches between cells. Such stress can reduce power output and accelerate device degradation. Reverse-bias stress occurs when parts of a solar cell operate under an abnormal electrical ...Den vollständigen Artikel lesen ...
