Abstract
Solar Energy is one of the most viable and renowned energy sources for reduced carbon emission and Greenhouse effect. However, efficiency of solar cells is the most upsetting factor leading to advanced research in solar materials & their characterization. Manufacturing of reliable solar cells are not gaining attention due to heavy competition in the market for reduced prices of solar. In this paper, characterization and analysis of the polycrystalline solar cell samples which are collected from renowned industries are performed using EDAX APEX & SEM. Spectrum Analysis, Line Analysis and Mapping of the samples are done to identify how the materials are scattered in the cells with and without Silicon Nitride Layer. This analysis is intended to find the root cause for lesser efficiency in cells and also efficiency of the solar cell consider will be increased from 16 to 17.5% after coating with SiNx.
