Description
Technical field
The utility model belongs to the photovoltaic cell technology.
Background technology
Existing concentrating solar battery system can only utilize focus irradiation by single, and the photon utilance is low.Also exist the open-air aging fast problem such as fragile of cooling cost height, photocell simultaneously.
Summary of the invention
The purpose of the utility model is to provide a kind of solar energy converting efficient the high interior photovoltaic power generation apparatus of laser pump cavity that also can adapt to adverse circumstances, and is as shown in the figure, comprises pedestal, solar tracking device and support; The upwards fixing parabolic reflector condenser of support; The parabolic reflector condenser has edge, it is characterized in that reflective concave surface mirror of support upper fixed on the edge of, is provided with cylindrical hollow light pipe under it; This light pipe passes the parabolic concentrator center hole and is fixed in parabolic bottom; A spherical hollow space is fixed on the pedestal, and spherical hollow space has light well, and ball-type cavity light hole is aimed in the light pipe outlet; The spherical hollow space inwall is covered with silicon light solar battery sheet through connection in series-parallel, and an INFRARED ABSORPTION filter is installed on the light well.Because paraboloidal mirror overlaps with the concave mirror focus, so concave mirror will reflect a branch of quasi-parallel sunlight, this Shu Yangguang gets into spherical hollow space through light pipe and spherical hollow space light well, produces photovoltaic effect output electric energy at incident sun lights lower chamber.Parabolic concentrator is installed on the solar tracking device, and its structure does not influence under any tracing positional quasi-parallel sunlight and injects spherical hollow space.The spherical hollow space light well is blocked by the INFRARED ABSORPTION filter, plays the effect of heat insulation, separated rain, dust-separation.Outward flange at the INFRARED ABSORPTION filter is equipped with thermal conductive metal plate, and thermoelectric cell is installed in the outside of thermal conductive metal plate, and the high temperature face of thermoelectric cell is close to thermal conductive metal plate, and the low temperature face places ambient temperature.Install thermal conductive metal plate and thermoelectric cell additional and can realize the thermoelectric conversion using on the INFRARED ABSORPTION filter disc.
It is tens of times of silicon photocell area that this device can be designed to the spherical hollow space internal surface area with paraboloidal mirror collection area (light-receiving area); Make that silicon photocell is multiplied by the more common intensity of sunshine of luminous intensity in the chamber; Constitute a kind of novel solar energy light gathering battery; The photoelectric conversion rate that not only has been multiplied, and saved the photocell consumption greatly.Because the photon of going into to inject in the cavity can only produce the utilization of reflection photovoltaic, so this system has improved the photon utilance greatly at intracavity reflecting.The INFRARED ABSORPTION filter stops that the photon that heats that does not produce photovoltaic effect more than the 1200nm gets in the chamber; Efficiently solve condensation photovoltaic battery cooling problem; Reduce the concentrator cell cost, because this system places silicon photocell in the chamber, completely cut off the many adverse factors under the open-air open-air atmosphere in addition; Can improve the useful life of battery sheet greatly, reduce system cost.
