Abstract
A sunlight energy conversion apparatus comprises a photoelectric transducer comprising a non-single crystal semiconductor and means for supplying heat to the photoelectric transducer through a flowing heating medium.
Claims40
A sunlight energy conversion apparatus comprising a photoelectric transducer comprising a non-single crystal semiconductor and an air flow path provided on the back of said photoelectric transducer and having a plurality of selectable air intakes.
A method of controlling the temperature of a photoelectric transducer, which comprises allowing air to flow through an air flow path provided on the back of the photoelectric transducer comprising a non-single crystal semiconductor to control the temperature of said photoelectric transducer.
An air circulation system comprising a heat collector panel comprising an open-air intake, an indoor-air intake, valve for selecting either the open-air intake or the indoor-air intake, an air flow path, an air outlet, and a solar cell, a first duct through which the air taken out of the air outlet is guided indoors, a second duct through which the air taken out of the air outlet is discharged outdoors, a valve for selecting either the first duct or the second duct, and a fan for allowing the air taken through the air outlet to flow.
A sunlight energy conversion apparatus comprising an amorphous photoelectric transducer;
- and a flow path formed by a space provided on a side opposite to a light incidence side of the photoelectric transducer, for providing a heating medium with the thermal energy of the sunlight irradiated to the photoelectric transducer and having a plurality of selectable inlets and an outlet for inflow/outflow of the heating medium.
A method of controlling the temperature of a photoelectric transducer which comprises:
- (a) selecting either open-air or indoor-air based on the temperature of a photoelectric transducer, the outdoor temperature, the indoor temperature, and the amount of solar radiation;
- and
- (b) allowing the selected air to flow into said photoelectric transducer to control the temperature of said photoelectric transducer.
