Perovskite PV continues to deliver encouraging results pointing to a future in which pervoskite-silicon or perovskite-thin film cells deliver conversion efficiencies significantly in excess of 20%. The Swiss Federal Laboratories for Materials Science and Technology (EMPA) is the latest to publish results in the this field, having developed a low-temperature process to produce semi-transparent perovskite cells. The EMPA team employed a "hybrid thermal evaporation-spin coating technique" to produce a hysteresis-free perovskite PV cell, that can operate as a bifacial solar cell and in a tadem application due to its semi-transparent nature. An efficiency of 14.2% was achieved using the technique. Through employing a "high-mobility hydrogenated indium oxide" rear electrode, the cell achieves 72% near-red light transmittance. The rear electrode is deposited using room-temperature radio-frequency magnetron sputtering. By producing ...Den vollständigen Artikel lesen ...
