将太阳能电池板、集热器、热电发电片结合起来,设计并制成了一套光伏/热电(PT/TV)系统,在利用太阳能电池发电的同时,收集热量并利用其发电。在北京地区进行了该系统的室外模拟试验,测试并讨论了该系统在不同结构和不同环境下的性能,探讨该系统在光伏建筑中的应用。试验结果表明,与单纯的光伏发电系统或太阳能热水系统相比,PV/TV系统具有占地面积小、综合效率高等优点。
A novel hybrid photovoltaic/thermoelectric solar energy system was designed with pV cells combined with heat collector and thermoelectric generator. While the PV system converts the solar radiation into electric energy, the thermoelectric system can collect beat from the solar panels so that to reduce its surface temperature, and then to convert the heat into electricity directly by using of thermoelectric module. An outdoor simulation experiments were carried out in Beijing. The performance of this system was analyzed with different structure and different environment. The application of this system in photovoltaic building was discussed primarily. The overall efficiency of this system is higher than that of a pure PV system or a pure solar water heating system.
