Solar energy has been increasing its share in the global energy structure. However, the thermal radiation brought by sunlight will attenuate the efficiency of solar cells. To reduce the temperature of the photovoltaic (PV) cell and improve the utilization efficiency of solar energy, a hybrid system composed of the PV cell, a thermoelectric generator (TEG), and a water-cooled plate (WCP) was manufactured. The WCP cannot only cool the PV cell, but also effectively generate additional electric energy with the TEG using the waste heat of the PV cell. The changes in the efficiency and power density of the hybrid system were obtained by real time monitoring. The thermal and electrical tests were performed at different irradiations and the same experiment temperature of 22°C. At a light intensity of 1000 W/m², the steady-state temperature of the PV cell decreases from 86.8°C to 54.1°C, and the overall efficiency increases from 15.6% to 21.1%. At a light intensity of 800 W/m², the steady-state temperature of the PV cell decreases from 70°C to 45.8°C, and the overall efficiency increases from 9.28% to 12.59%. At a light intensity of 400 W/m², the steady-state temperature of the PV cell decreases from 38.5°C to 31.5°C, and the overall efficiency is approximately 3.8%, basically remain unchanged.

太阳能在全球能源结构中的份额一直在增​​加。但是，阳光带来的热辐射会降低太阳能电池的效率。为了降低光伏（PV）电池的温度并提高太阳能的利用效率，制造了由PV电池，热电发电机（TEG）和水冷板（WCP）组成的混合系统。WCP不仅可以冷却PV电池，而且还可以利用PVG的废热利用TEG有效地产生额外的电能。通过实时监控获得混合系统效率和功率密度的变化。在不同的辐照和22°C的相同实验温度下进行热和电测试。在1000 W / m ²的光强度下，光伏电池的稳态温度从86.8°C降至54.1°C，整体效率从15.6％增至21.1％。在800 W / m ²的光强度下，PV电池的稳态温度从70°C降低到45.8°C，总效率从9.28％增加到12.59％。在400 W / m ²的光强度下，PV电池的稳态温度从38.5°C降低至31.5°C，总体效率约为3.8％，基本保持不变。
