Embodiment

[0027]The prepared photothermal conversion nanofluid and nanofluid cooling liquid are respectively injected into the high-temperature circulation pipeline and the low-temperature circulation pipeline, and the concentrating plate is adjusted to track solar radiation to perform solar photoelectric photothermal conversion.

[0028] The solar radiation is projected onto the concentrating plate. After the concentrating plate is concentrated, the solar radiation is projected onto the combined heat and power device. The full band of solar radiation passes through the glass interlayer, and the photothermal conversion nanofluid absorbs energy in the infrared band to obtain high-temperature heat; at the same time, the photothermal conversion The working fluid efficiently passes through visible light, and the energy in the visible light band is projected on the battery panel through the lower surface of the interlayer glass for photoelectric conversion to obtain electrical energy; the surf...

Abstract

The invention discloses solar united system of concentrate light and pyroelectricity. It has condenser plate and the pyroelectric united device set on condenser zone on the condenser plate. The pyroelectric united device is set with an outer insulating layer of glass, solar cell plate were set under the glass, with cooling conduit which links nano cooling fluid set under the cell plate, the cooling conduit of pyroelectric united device are connected with the cryogenic circulating conduit sequentially installed with cryogenic heat exchanger,cryogenic circulating pump and cryogenic governor valve; the cavity of pyroelectric united device is connected with the high-temperature circulating conduit sequentially installed with high-temperature heat exchanger,high-temperature circulating pump and high-temperature governor valve. The invention complex utilizes the photo electricity and photo-thermal; improve photovoltaic conversion efficiency when the heat is used. The condenser technology reduces the utilization area of photovoltaic battery panels; great reduce the system investment, with a very broad market prospect.

Description

technical field [0001] The invention relates to solar light-to-heat conversion and photoelectric conversion technologies, in particular to a solar concentrating heat and power (CPVT) system. Background technique [0002] my country is rich in solar energy resources, and the annual radiation in 2 / 3 areas is greater than 5020MJ / m 2 , The annual sunshine hours are more than 2200 hours, the development and utilization of solar energy has great potential. At present, solar energy utilization technologies mainly include basic methods such as photothermal conversion, photovoltaic power generation, and photochemical conversion. Photovoltaic power generation can obtain high-grade electric energy products, but its main problems are low photoelectric conversion efficiency, high cost, and narrow utilization range of sunlight. The main features of light-to-heat conversion are high efficiency and low cost, and can utilize almost all solar energy bands. However, compared with photoelectr...
