摘要
根据染料敏化太阳电池的工作原理,对其热效应进行分析,通过数值模拟计算,得出电池内温度分布和变化情况。结果表明:当环境温度为26.5℃、辐射强度500 W/m~2时,过25 min后电池温度达到最高温度约46℃;相同条件下,实验与模拟的温度变化曲线基本吻合,验证了模拟计算的正确性;当环境温度为37℃、辐射强度1000 W/m~2时,电池最高温度约至79℃,达到电池效率下降的温度。该文可为实际电池应用热分析、结构优化及冷却设计等提供计算手段。
The thermal effect was analyzed based on the working principle of dye-sensitized solar cells. The temperaturedistribution and variation in the cell were gotten by means of the numerical simulation. The results show that under theenvironment temperature condition of 26.5 ℃ and the radiation intensity of 500 W/m~2, the highest temperature of cell canreach around 46 ℃ after 25 minutes. The temperature variation curves of experiment and simulation are basicallyanastomosis under the same conditions. The results verify the validity of the simulation calculation. Nevertheless, underthe environmental temperature condition of 37 ℃, the radiation intensity of 1000 W/m~2, the most high temperature canreach about 79 ℃ which reaches the temperature of the cell efficiency decrease. The present research provides acalculation method for the thermal analysis, structure optimization and the cooling design of the actual cell application.
