A research team in Bangladesh has simulated a perovskite-CIGS PV device that can reportedly achieve a remarkable tandem cell voltage of 2.48 V. The proposed method is also applicable for tandem cells composed of other materials.A group of researchers in Bangladesh has designed and simulated an all-inorganic lead-free tandem photovoltaic cell based on copper, indium, gallium and selenium (CIGS) thin-film technology and perovskite. The novel device architecture is claimed to have the potential to reach a power conversion efficiency of 38.39%. "The main objective of this work is to find an efficient ...Den vollständigen Artikel lesen ...
