背景技术 Background technique
太阳能是一种可再生的清洁能源，具有普遍性，目前利用太阳能发电的方式主要有光伏发电和聚光光热发电。半导体温差发电主要通过在利用赛贝尔效应原理制作的半导体温差发电片两端形成热端和冷端，造成温差产生电动势发电，温差越大发电量越多。聚光可以使得分散的太阳光汇聚在一起，形成一个温度较高的小区域。 Solar energy is a renewable and clean energy with universality. At present, the main methods of using solar energy to generate electricity are photovoltaic power generation and concentrated photothermal power generation. Semiconductor thermoelectric power generation is mainly through the formation of hot and cold ends at both ends of the semiconductor thermoelectric power generation sheet made by the Seibel effect principle, causing the temperature difference to generate electromotive force power generation, the greater the temperature difference, the more power generation. Concentration allows scattered sunlight to be brought together to form a small area of higher temperature.
