“…Authors also presented new methods which minimize hotspots by 17% in shaded solar cells in addition to minimizing power loss in whole of PV system 55) . Various new techniques such as Impedance Spectroscopy have been used to identify the level of degradation by analyzing the ac parameters of solar cell 56) .The performance of solar cell under different shading ration and shading pattens is identified by performing experimental study on mono and poly crystalline solar panels 57) .Condition like shading still impacts the output power even after adopting various MPPT techniques, thus certainly it is not a healthy phenomenon for the entire PV system. This study aims as to evaluate the effect of shading phenomena so that there could be better ways searched out to minimize the impact of shading and increase the reliability and durability of a PV module.…”

The photovoltaic (PV) have their installations in outdoor conditions where they face several unfavorable conditions and one of them is shading. One form of shading is partial shading that create mismatch among solar PV cells consequently disturbing electrical outputs and performance of a PV array output and hence power losses are created. A lot of information can be gathered just by observing the shape and magnitude of the curves obtained from I-V & P-V characteristics of the photovoltaic array. The I-V & P-V characteristics under shading also show changes in their usual shape which is analyzed in our research paper using MATLAB/Simulinkbased simulation results by examining the variation in the characteristics of a series-parallel photovoltaic array configuration under partial shading conditions. The simulated results show existence of multiple peaks and steps in the I-V & P-V characteristics. The second part of result section show a comparative study among different partial shading condition and the mismatching power loss is estimated to be 27.16%, 29%, and 42.8% for partial shading pattern cases 2, 3, and 4, respectively. This paper will help readers and researchers with a clear idea of what shading is and how it affects the output of photovoltaic systems with a change in shading.

“…Modules that contain PV cells have a polymeric encapsulation that protect them from environmental factors such as weather, corrosive environments, UV rays, low mechanical stress, and minimal energy impacts [28]. The material used as the encapsulant is most frequently ethyl vinyl acetate (EVA) [29].…”

Green energy transition and climate change have gathered significant momentum in the world because of the rising population and increased clean energy demands. For this reason, renewable energy alternatives such as inexhaustible photo energy from the sun appear to be the ultimate solution to the world's energy needs. Formamidinium tin tri‐iodide (HC(NH2)2SnI3)‐based perovskites are found to be more efficient and stable than their methylammonium tin tri‐iodide (MASnI3) counterparts because of its wider bandgap and better temperature stability. A device simulation of FASnI3‐based solar cell is numerically performed using solar cell capacitance simulator (SCAPS‐1D). The focus is to investigate the effect of changing working temperature, metal back contact, absorber thickness, defect density, and doping concentration on the performance of the proposed solar cell device. The optimised solar cell parameters of the proposed solar cell were: short‐circuit current density (Jsc) of 28.45 mAcm−2, open‐circuit voltage (Voc) of 1.0042 V, fill factor of 63.73%, and power conversion efficiency of 18.21% at 300 K, thus, paving the way for novel perovskite solar cells which are environmentally benign because they are lead‐free, have better absorption efficiency, and can be injected into the production work flow for commercial applications.
