Hybrid organic-inorganic perovskite solar cells (PSCs) offer a highly promising solution for achieving low-cost, high-performance photovoltaics. However, to accelerate the development of the PSC technology, it is critical to quantify local performance losses and identify problematic regions across the device.
The main focus of solar cell design is to increase their conversion efficiency. This paper focuses on methods for increasing the conversion efficiency of solar cells, which can lead to more efficient energy for space technology.
Photovoltaic cells (made of semiconductor material) absorb photons, elementary particles present in sunlight. The absorbed photons excite the electrons present in the photovoltaic cell and the movement of these electrons generates an electric current. In solar thermal conversion, solar energy is stored in the form of thermal energy.

5.1.3. Emission loss According to Kirchoff's law, materials that absorb light must also emit light, and this emission from the solar cell contributes to a decrease in conversion efficiency (Dupré et al., 2016). The loss of photons emitted by the cell due to radiative recombination is known as emission loss.
