Effect of Environment Temperature on Photovoltaic Parameters for Silicon Solar Cell
Rasool R. Attab
In this study, an accurate description of some of the variables affecting the generation of electrical energy from solar cell structures of the type Silicon was investigated, these variables were affected by the difference in the temperature of the surrounding medium from 20 to 80 degrees Celsius, taking into account the optical energy that was located between 300 to 850 watts. Per square meter, it became clear from the results that the effect of temperature has a direct impact on each of the variables (open circuit, fill factor, maximum power, efficiency), where it turns out that the latter decreases with increasing the temperature of the photocell.
The increase in the temperature of the optical cell increases the short circuit current, and therefore we find an increase in the reverse saturation current with an increase in temperature, the above influences turned out to be negative values except for short circuit current values. It became clear through the study that the relative change was directly dependent on the change in temperature and thickness, which was within the limits (0.576 to 0.555) volt for open circuit, (0.769 to 0.606) fill factor, (1.59 to 1.04 %) maximum power efficiency, respectively, these values are somewhat similar to what is found in research and studies, as well as computer simulations which identify the single diode model for the solar cell.
