Based on the energy balance and conversion principle, a thermal and electrical model for the solar photovoltaic/thermal (PV/T) system is developed to solve coupled thermal and electrical parameters by using the iteration method of MATLAB. The variation of thermal and electrical efficiency is given and the influence of the PV/T system assembly length and working medium velocity change on the performance curve of the PV/T system is analyzed. Experimental study is conducted to compare the simulated results with the experiment data of general photovoltaic assembly including voltage, current, power and temperature of the back panel. ©2015 Automation of Electric Power Systems Press

Concerning the problem of non-uniform temperature of GaAs solar cell module in a new Fresnel three-stage high-concentration Photovoltaic/Thermal system, Helix microchannels cooling structure be designed using for cooling GaAs solar cell. And on this basis influencing factors of battery temperature, outlet fluid temperature, thermal efficiency and comprehensive efficiency can be investigated including the length of the microchannel, PCB area and fluid inlet velocity, meanwhile the structure be optimized, and the results show that for the monolithic GaAs cell the heat transfer effect is best for PCB board area of 127×127, and he helix microchannels cooling structure with flow channels length of 6 lap in this article, and if it can be used in membrane distillation desalination of brackish water system of heat of 65 ~ 70 ℃ outlet fluid, the inlet fluid velocity should be controlled within 0.52 ~ 0.58 m/s. The study can provide theoretical bases for heat transfer characteristics experimental study of the cooling system and the application in Fresnel high concentrated PV/T. © 2015, Science Press.
