Layered Ruddlesden Popper Perovskites with Various Thicknesses for Stable Solid-State Solar Cells

Аннотация

Systematic studies showed that morphology, crystal structure, optical properties, photovoltaic performance, and internal resistances of this compound depended upon the value of the n integer. Field emission scanning electron microscopy set forth that the deposited films were composed o f various morphologies depending on the n value. An increase in the n value resulted in improving the light absorption, reducing the band gap energy, and blue-shifting the photo luminescence peak.
