The invention relates to a large-area transmission condensation solar photoelectric photo-thermal
daylighting building member quadruple
coupling device, which mainly comprises
light transmission glass (1), a
solar cell (2), a rectangular heat collection
pipe (3), an inner plate (4), an outer frame (5), an angle changing mechanism (10) for regulating the change of a solar
declination angle and a translation mechanism (11). The quadruple
coupling device is characterized by combining four functions of solar
photovoltaic power generation, the generation of
heat energy,
daylighting and building members. Under the
irradiation of sun light, a plurality of groups of strip condensation belts of which the area is only a fraction to several tenth of the
irradiation area of the sun light are formed on the condensation surface below the
light transmission glass (1); the
solar cell (2) is arranged on the condensation belts to reduce the using amount of the
solar cell (2); and water (or air) in the rectangular heat collection
pipe (3) which lean against the reverse side of the solar
cell (2) is cooled to carry away heat, so that the temperature of the solar
cell (2) is not high. The large-area transmission condensation solar photoelectric photo-thermal
daylighting building member quadruple
coupling device realizes one device with four purposes, is low in cost and does not occupy lands.
Electric energy,
heat energy and daylighting which are generated by utilizing the quadruple coupling device serving as the building members such as roofs, windows, walls and the like at the sunshine position can be supplied to the production and living of people.
