Light-condensing heat-collecting and power-generating solar energy comprehensive utilization device

Abstract

The invention provides a light-condensing heat-collecting and power-generating solar energy comprehensive utilization device. The solar energy comprehensive utilization device comprises a light-condensing heat-collecting part used for gathering solar energy for generating heat, a photovoltaic power generation part which is arranged at the side, facing the sun, of the light-condensing heat-collecting part and used for converting light energy into electric energy, and a light reflection part which is arranged between the light-condensing heat-collecting part and the photovoltaic power generation part and used for reflecting light. The photovoltaic power generation part is arranged at the side, facing the sun, of the light-condensing heat-collecting part , so that in the high-temperature state, the photovoltaic power generation part can convert the solar energy into the electric energy, the photovoltaic power generation part can effectively reduce outward radiation heat of the side, facing the sun, of the light-condensing heat-collecting part, and the heat loss of the light-condensing heat-collecting part can be reduced. The light reflection part is arranged between the light-condensing heat-collecting part and the photovoltaic power generation part, so that part of light gathered by the light-condensing heat-collecting part can be prevented from irradiating the photovoltaic power generation part, and the photovoltaic power generation part can be prevented from being damaged. Meanwhile, the light reflection part can reflect heat radiation of the light-condensing heat-collecting part, so that the heat loss of the light-condensing heat-collecting part can be reduced. 本发明提供了一种聚光集热和发电的太阳能综合利用装置，包括：聚光集热部，用于聚集太阳光能产热；光伏发电部，设置在聚光集热部朝向太阳的一侧；光伏发电部用于将光能转化成电能；反光部，设置在聚光集热部与光伏发电部之间；反光部用于反射光线。光伏发电部设置在聚光集热部朝向太阳的一侧，因此，在高温状态下，光伏发电部不仅能够将太阳光能转化成电能，并且光伏发电部能有效降低聚光集热部朝向太阳的一侧向外辐射热量，可降低聚光集热部的热损。反光部设置在聚光集热部与光伏发电部之间，可避免聚光集热部聚集的部分光线照射到光伏发电部上，可避免光伏发电部被损坏。同时，反光部还可反射聚光集热部的热辐射，可减小聚光集热部的热损。
