No solar technology has developed as rapidly as perovskite. The efficiency of perovskite solar cells now exceeds that of thin-film technologies, such as CdTe (cadmium telluride) and CIGS (copper indium gallium selenide). And the efficiency of perovskite solar cells is currently only slightly below that of silicon solar cells.
Organic–inorganic hybrid perovskites have been widely used in silicon-based tandem solar cells for their advantages of tunable bandgap, high light absorption coefficient, and high power conversion efficiency (PCE). However, the maximum PCE of perovskite/silicon tandem solar cells (PSTSCs) is still below the theoretical limit.
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 .
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.
At least one of these electrodes (the front of the solar cell) is transparent. The stack of layers is about 1 micron – one thousandth of a millimetre – thick. This means that perovskite solar cells can be applied as very thin layers to all kinds of substrates: glass, foil, or another solar cell.
Efficient wide-bandgap (organic–inorganic and all-inorganic perovskites) and narrow-bandgap (Pb-Sn binary perovskites) PSCs are essential for promoting the development of PVK-based tandem solar cells. Usually, wide-bandgap perovskites are used as the front cells.
