Perovskite solar cells (PSCs) have attracted many researchers due to their excellent power conversion efficiency (PCE) of 25.2%, and can be a substitution for silicon solar cells as future technology. The efficiency of PSCs has been enhanced from 3.8% to 25% and has evolved to be better ...

The structureof perovskite solar cells differs slightly from the classical structure of Al-BSF c-Si solar cells. Perovskite solar cells can be manufactured using conventional n-i-p or p-i-n architecture, sandwiching the perovskite absorber layer between a Hole Transporting Layer (HTL) and an El...
(CaTiO3), and hence the chosen materials for the designing of the perovskite solarcells having the same crystal structure as CaTiO3. The general chemical formula of perovskite is ABX3, where A-site is the cation and coordinated it to the 12 sites of anions and forms the cuboctahedron; ...

In recent years, the power conversion efficiencies (PCEs) of organic-inorganic metal halide perovskite solar cells (PSCs) have been dramatically elevated from 3.8% to 21.0%. This remarkable progress is closely associated with the specific photoelectrical properties of perovskite light absorbers, such ...

Perovskite solar cells (PSCs) are photovoltaic (PV) devices containing a light-absorbing layer that has the general formula AMX3,[1] and a crystal structure similar to the mineral perovskite (CaTiO3). The advantageous electronic and optical properties of perovskites have contributed to impressive ...
