Also, the influence of light intensity on the power generation performance of solar cells was evaluated in Ref. . While analysing the electrical performance parameters of photovoltaic cells, the complexity was reduced by discarding weakly related parameters and determining the main influencing factors. ... ...
PV parameters are dependent on light source and illumination intensity. Thin-film amorphous silicon solar cell reaches 20% efficiency in LED illumination. Experimental characteristics are correlated to basic theoretical predictions. The performance of a solar cell is inherently dependent on the illumination spectrum and intensity.
In this study, we introduce a simple method of FF and Voc analysis as a function of light intensity to understand the performance-limiting mechanism. So far there are no comprehensive studies that would help to fully understand the effect of these parameters (especially FF) on the operation of the solar cell.
Solar cells experience daily variations in light intensity, with the incident power from the sun varying between 0 and 1 kW/m 2. At low light levels, the effect of the shunt resistance becomes increasingly important.
Light intensity study of the JV parameters has become more popular in the last few years, claiming for example that it can make a correlation between trap densities and cell performances. In this study, we introduce a simple method of FF and Voc analysis as a function of light intensity to understand the performance-limiting mechanism.
Besides, G was observed to increase with the increment of light intensity fall on the cell . Therefore, J SC was highest under LED light and least under CFL light. ... ... Increasing light intensity increases open circuit voltage of solar cell logarithmically .
The experimental results show that the open circuit voltage, short-circuit current, and maximum output power of solar cells increase with the increase of light intensity.
