چکیده انگلیسی:
The solar photovoltaic (PV) systems are facing serious problems due to unavoidable losses in their system, leads to more devation of output power from the input power level. This effect is known as a mismatch effect and is available in PV systems. Many losses are encountered in PV system and it is difficult to minimize such losses. In this paper, the influence of thermal effect on the solar PV system is considered and its influence on the performance of the operation, fill factor, open circuit voltage, and short circuit current, band gap level of various semiconductor materials, output power and efficiency are analyzed. The temperature effect of a solar PV cell, while connecting in a 36 cells in a module is analyzed for the various connection configurations like Simple Series configuration (SS), Series-Parallel configuration (SP), Total-Cross Tied configuration (TCT), Bridge-Linked configuration (BL), and HoneyComb configuration (HC) using MATLAB software. Increases the level of temperature for various connection configurations, correspondingly decreases their open circuit voltage, series resistance. Shunt resistance and current are may not fully affects due to temperature. Finally this problem creates a heating effect in the solar PV cell, so the life span of the photovoltaic panel is decreased gradually. While increases the temperature level soldering points are affected and cell encapsulation is affects. Solar cell materials are changed their performance of operation,while changes in the band gap with the effect of temperature.
