The hot spot effect can cause solar panels to overheat locally, reducing their efficiency and potentially causing damage. Details are as follows: 1.Efficiency degradation: When hot spots occur in solar panels, the local temperature rises, which usually leads to a decrease in the performance of the solar cell as the temperature rises. At high
Suppressing the interfacial non-radiative recombination plays a critical role in reducing the voltage loss of perovskite solar cells. Herein, we develop a holistic interfacial regulation using dielectric materials of Al 2 O 3 and PEABr/PMMA, and a buffer layer of compact SnO X to manipulate the multiple interfaces. A compact SnO X is inserted to reduce the

Lead halide perovskite solar cells (LHPSCs) brought significant attention in photovoltaics [1], [2], [3], [4].Their unique useful features including the wider range absorption, long charge carrier diffusion length, and tunable bandgap play a significant role in attaining higher photoconversion efficiency (PCE) [5], [6], [7], [8].Over a decade of timeline, the PSC raised its
Perovskite solar cells combine high carrier mobilities with long carrier lifetimes and high radiative efficiencies. Despite this, full devices suffer from significant nonradiative recombination losses, limiting their V OC to values well below the Shockley–Queisser limit. Here, recent advances in understanding nonradiative recombination in perovskite solar cells from

Dust from agricultural and industrial emissions, pollen, plant debris, fungi, mosses, algae, bacteria biofilms, bird droppings, and mineral dust deposits are just a few of the many types of location-dependent contamination that can block and scatter sunlight, affecting the overall efficacy of solar PV cells (Zeedan et al., 2021).
From Fig. 1, we can find that light, heat, moisture and reverse bias are the main threats for solar cells to face under outdoor working conditions in addition to the mechanical stress.

Degradation of silicon solar cells is dominated by four modes:potential-induced, light--induced, wafer cracking, and metal corrosion. These modes affect the cells in different ways and may range from almost no loss of power to complete loss of power. 4.1. Introduction to the Physics of Photovoltaic Devices
Because of solar irradiance and cell temperature, which are two parameters that affect the efficacy of a PV module, the accumulation of dirt on solar panels (“soiling”) can have a major impact on the performance of PV systems (Kimber et al., 2006). Solar irradiation and cell temperature influence PV output power (Ibrahim, 2011).
Related to the brittleness of silicon as well as the relative thinness of the industrial wafering process, silicon solar cells arehighly prone to breakage through cracking. The cracking of the cells may or may not be deleterious, dependent upon the size and direction of the crack (s).
Solar cells in practical applications are supposed to cope with varied weather conditions, of which temperature and humidity are the crucial factors. In the IEC standard, three stability tests of thermal cycling, damp heat and humidity freeze correlate closely to the two factors.
