The working principle of Perovskite Solar Cell is shown below in details. In a PV array, the solar cell is regarded as the key component . Semiconductor materials are used to design the solar cells, which use the PV effect to transform solar energy into electrical energy [46, 47].
The application of mesoporous materials in perovskite solar cells allows the perovskite absorber to adhere to the mesoporous metal oxide framework for the purposes of increasing the light-receiving area of the photosensitive material and improving the efficiency of the device.
Electrons are transferred from the perovskite material to TiO 2, which is used for the ETM layers and finally collected by FTO. At the same time, the holes are transferred to the HTM layer and collected by the metal electrode.
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.
According to statistics, the power generation of 35kg perovskite is the same as that of 7 tons of silicon, so the use of perovskite materials is reduced by a hundred times).
The initial evolution of perovskite solar cells relied on the charge extracting materials employed. The progress on perovskite solar cell has been characterized by fast and unexpected device performance improvements, but these have usually been driven by material or processing innovations.
