【摘要】 太阳能储量巨大,分布广泛,清洁安全。但太阳能光伏发电存在成本较高和能量转化效率较低的问题。因此本文提出太阳能光电-光热综合利用方式。通过聚光降低成本,通过分频综合利用提高系统效率。在分频利用技术上,寻找具有特定吸收发射特性的纳米流体流经光伏电池上层,吸收光伏电池不能加以利用的部分能量。此外,利用光学薄膜,将光伏电池可利用的波段反射给光伏电池,其余部分的能量透射用以其他形式的能量转换。文章对两种太阳能光电-光热综合利用系统进行了设计和探索。结果表明,通过光电-光热综合利用能够对太阳能利用效率实现有效提升。更多还原

【Abstract】 solar energy is enormously reserved, widespread, safe and clean. But solar energy photovoltaic power cost is high and its conversion efficiency is low. So this article brings up Solar energy optic-electro and optic-thermal composite utilization. Through spotlights cost reducing and frequency division utilization it improves system efficiency. Based on frequency division technology, some specific absorption-emission characteristic nanometer fluid passing above photovoltaic battery will absorb some energy which can not be used by photovoltaic batter. Otherwise it will use optical thin-film to reflect some wave band which photovoltaic battery can use to photovoltaic battery, as for the rest energy, it will transmit into other means of conversion. This article discuss two ways of solar energy, designs and explores optic-electro and optic-thermal composite utilization system. The results shows that solar energy use efficiency improves a lot through optic-electro and optic-thermal composite utilization.更多还原
