Among renewable energy resources, solar energy offers a clean source for electrical power generation with zero emissions of greenhouse gases (GHG) to the atmosphere (Wilberforce et al., 2019; Abdelsalam et al., 2020; Ashok et al., 2017).The solar irradiation contains excessive amounts of energy in 1 min that could be employed as a …
Optical losses chiefly effect the power from a solar cell by lowering the short-circuit current. Optical losses consist of light which could have generated an electron-hole pair, but does not, because the light is …
(b) Light-Induced Degradation (LID): LID is the loss of power incurred during the infant stage of a PV module due to the initial exposure to sunlight.LID occurs in amorphous as well as crystalline silicon solar cells. It is more severe in a-Si solar cells and degrades its efficiency by up to 30% [] and better described as "Staebler-Wronski" effect.
To study the loss processes in solar cells systematically, in this paper, the concept of external radiative efficiency is used to quantitatively analyze the recombination …
