What are the different types of perovskite solar cells?
Different types of perovskite solar cell Mesoporous perovskite solar cell (n-i-p), planar perovskite solar cell (n-i-p), and planar perovskite solar cell (p-i-n) are three recent developments in common PSC structures. Light can pass through the transparent conducting layer that is located in front of the ETL in the n-i-p configuration.
What is a sensitized perovskite solar cell?
Schematic of a sensitized perovskite solar cell in which the active layer consist of a layer of mesoporous TiO 2 which is coated with the perovskite absorber. The active layer is contacted with an n-type material for electron extraction and a p-type material for hole extraction. b) Schematic of a thin-film perovskite solar cell.
What is a mesoporous perovskite solar cell?
Mesoporous perovskite solar cell (n-i-p) The Mesoporous Perovskite Solar Cells (MPSCs) have recently drawn greater interest due to their inexpensive components, simple manufacturing process, and high PCE. In MPSC, a fluorine-doped tin oxide layer (FTO), which typically blocks holes and collects electrons, is placed before the compact layer .
What are perovskite silicon tandem solar cells?
Perovskite silicon tandem solar cells are created by stacking a perovskite absorber layer (including HTL and ETL), on top of an n-type c-Si layer, featuring a recombination layer between them, made out of hydrogenated a-Si (a-Si:H) or nanocrystalline silicon (nc-Si).
