Development of Stable and Optimized Bandgap Halide-Chalcogenide Perovskite Materials for Photovoltaic Applications

The toxicity and instability of some metal-halides has made it unfovarouble to be used for

the development and fabrications of perovskites despite its good Power Conversion

Efficiencies (PCE). The need to suggest good perovskites absorber materials that has excellent

Dimensionality, optical band gap, and power conversion efficiencies to substitute lead in

photovoltaic application is very essential in the recent research. This research work reviewed

and suggested the combinable good perovskites absorber materials that can substitute lead

in the perovskites. This research further discussed the possible alternative elements to

replace lead in metal halide perovskites and the properties of the corresponding perovskite

materials based on recent theoretical and experimental studies. In this research work other

elements such as germanium, copper, antimony, bismuth, and the corresponding perovskite

compounds are already showing promising properties
