Solar generating heat-collecting system high in photoelectric or photothermal conversion efficiency

Abstract

The invention relates to a solar generating heat-collecting system which meets the requirements of both generating and heating and is high in photoelectric or photothermal conversion efficiency. The solar generating heat-collecting system comprises an optical collector for enabling light to be overlaid in parallel and a parallel light receiver which is adjacent to an optical collecting belt of the optical collector. The parallel light receiver comprises a solar cell and a solar heat-collecting pipe which are integrally arranged in a back-to-back mode. When a solar power source is needed, the solar cell of the parallel light receiver is opposite to a reflecting surface of the optical collector; and when a liquid heat source is needed, the parallel light receiver is overturned, so that the solar heat-collecting pipe is opposite to the reflecting surface of the optical collector. Due to the fact that the optical collector is adopted, the photoelectric or photothermal conversion efficiency is high, and power supply or heat supply can be selected as needed.

Description

[0001] This application is a divisional application. The invention and creation name of the original application is "solar power generation and heat collection system", application number: 201110085377.8, and application date: April 6, 2011. technical field [0002] The invention relates to the technical field of solar energy concentration heat collection and power generation, in particular to a solar power generation heat collection system. Background technique [0003] Existing solar power generation or heating equipment often can only achieve a single function, that is, when using heat, there is no external power supplement; when generating power, the waste heat generated needs to be dissipated at a cost. Solar cells do not have constant temperature control. When there is sufficient sunlight and the ambient temperature is high, the solar cells’ power generation efficiency will decrease due to temperature rise, and some may even be damaged.

[0003] Existing solar power generation or heating equipment often can only achieve a single function, that is, when using heat, there is no external power supplement; when generating power, the waste heat generated needs to be dissipated at a cost

Solar cells do not have constant temperature control. When the sun is sufficient and the ambient temperature is high, the solar cells’ power generation efficiency will decrease due to temperature rise, and some may even be damaged.
