Abstract
The most direct effect on the efficiency is the temperature of solar modules. I discussed the reasons why the temperature of modules can affect the efficiency of solar cells and the explanation of how can we improve the solar system to decrease the influence of high cell temperature. The scarcity of traditional energy increases, so the scale of use of renewable energy increases. The efficiency of the energy-generating system is the most important factor that users consider. The extent of change in the temperature of solar modules is the highest, so the temperature of solar modules can cause an influential decrease in the efficiency of energy generation. I have used the data based on experiments set by other authors to illustrate the extent of influences of four main variables on the efficiency of the solar cells. I used of the properties of air and water to design two schemes to minimize the effects of high temperatures of solar cells. I compared the change in efficiency under one unit increase in variables. All of the data used in calculating or referring are from different experiments done by different authors. I connected the results with real conditions to determine the most influential variables-temperature of modules. Based on the theoretical result, the shading effect has the largest value of decrease in efficiency, so the effects of shading are considered by manufacturers a lot. Based on real-life situations, the scale of change in the temperature of modules and the actual temperature of modules are always higher than the standard operating temperature, 25℃, so the temperature of modules is the most influential variable. Monocrystalline silicon solar cells have different extents of influence of variables to polycrystalline silicon solar cells, these two types of solar cells are suitable to be installed in regions with low humidity. However polycrystalline solar cells are more sensitive to increases in the temperature of modules, so they need to pay more attention and avoid the effects of high temperature of modules.
