Effect of module operating temperature on module efficiency in photovoltaic modules and recovery of photovoltaic module heat by thermoelectric effect

One of the parameters affecting efficiency photovoltaic (PV) modules and PV systems is temperature. The factors that increase temperature in cause loss efficiency. In this study, experiments have been conducted with aim re ducing module For purpose, four polycrystalline monocrystalline modules, all same features, were used. A pair used as reference modules. study to reduce operating while also decreasing transient fluctuations system, order prevent reason, current, voltage power values examined relationship between these has explained. As a result, measured at 30-80°C 30-50°C heat pipe 30-37°C using pipes phase-changing material, 30-66°C material flexible surfaces. If increased by 35°C, decreases 10%. Heat PCM balance PV/T/PCM caused 1%. addition, electrical energy produced from accumulated on surface means Thermoelectric Generator (TEG). When difference surfaces 15°C, naturally cooled TE provides 0.45V output, forced-cooled TEG 0.97V output. gap increases, current increase. Briefly, TEG’s up 5W depending
