Abstract

This paper presents comprehensive study on performance comparison of different photovoltaic technologies, when subjected to five distinct proportions of temperature and humidity in a controlled environment under biasing conditions. The study considers five different PV (Photovoltaic) technologies (Mono, Multi, a-Si, CdTe, CIGS) based on their electrical parameters. It is observed that CIGS (Copper Indium Gallium Selenide) performs with best efficiency at 60 °C, 60% RH (relative humidity) while CdTe performs with best efficiency at 85 °C, 85% RH.The descriptive statistics shows that the largest possible Variance in Maximum Power of a-Si out of all available technologies is about 20.85 whereas the lowest noted in Mono C-Si is 0.917. The variability of data is further checked using Analysis of Variance tool. Finally the study establishes the performance dominance of C-Si (Mono) technology over all the thin film technologies based on stress tests and evaluation through the repeated measurement of maximum Power, module efficiency and cell efficiency.
