Ann-typesemiconductor contains one or more impurities based on pentavalent atoms like phosphorus, arsenic, antimony, and bismuth. Ap-typesemiconductor has dopants with five electrons in its valence layer. Phosphorus is commonly used for this purpose, as well as arsenic, or antimony. Uses of Semicon...
Commercialization is widely believed to be achievable for metal halide perovskite solar cells with high efficiency and low fabrication cost. However, stability remains a key obstacle for them to compete with established photovoltaic technologies. The pho
