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.
The carrier transport materials The perovskite solar cell devices are made of an active layer stacked between ultrathin carrier transport materials, such as a hole transport layer (HTL) and an electron transport layer (ETL). The band alignment depends on their energy level, electron affinity, and ionization potential.
In p-i-n structure perovskite solar cells (PSCs), the most prevalent electron transport layer (ETL), [6,6]-phenyl-C61-butyric acid methyl ester (PC61BM), acts as both electron extractor and protective coverage to the underlayer perovskite.
Perovskite is the crystal structure name of a calcium titanium oxide mineral composed of calcium titanate (CaTiO 3). This name is adapted by the solar cell com-munity to specify a group of organic-inorganic hybrid perovskites (OHPs). They have a general formula of ABX with the organic component (A = CH
Each component layer of the perovskite solar cell, including their energy level, cathode and anode work function, defect density, doping density, etc., affects the device's optoelectronic properties. For the numerical modelling of perovskite solar cells, we used SETFOS-Fluxim, a commercially available piece of software.
Perovskite solar cell (PSC) was initially developed based on dye-sensitized solar cell architecture; then planar thin film device architecture was later adapted. Until now, meso-scopic scaffolds and planar heterojunctions are still the two major architectures (Fig. 2).
