Abstract
The utility model provides a solar energy receiver for reflection type light concentration, which is used in matching with a parabolic reflection type condenser. The utility model comprises a heat dissipating substrate and at least one solar cell arranged on the heat dissipating substrate. The utility model is characterized in that: the surface of the solar energy receiver is a curved surface or an approximate curved surface, and has the focus basically coincide with that of the paraboloid of the reflection type condenser. As the receiving surface of the solar energy receiver for reflection type light concentration is a curved surface, even if the focal length of the surface is very short, energy distribution is still very uniform, and the uniformity degree exceeds the conditions of any long focal length. When the focal length is short, as the marginal overflow caused by sunlight divergence angle, the precision requirement of trackers is simultaneously reduced.
Description
Technical field
The utility model relates to a kind of device of solar generating, relates in particular to a kind of solar receiver that is used for reflection concentration type.
Background technology
Concentrating solar photovoltaic generating can reduce the photovoltaic generation cost significantly.Along with improving constantly of new and effective concentrator cell efficient, concentrating generating system will be more and more important in the solar energy power generating field.Light-gathering optics has various ways, and main application is parabolic reflector formula point focusing system at present, and the advantage of this system is: (battery can be changed) easy to maintenance; Be convenient to upgrading (can change more high efficiency battery); Light concentrating times is variable; Cost low (the speculum cost is low, and light concentrating times can be very high, to the demand minimizing of battery).But following shortcoming is arranged also: the one, when adopting long focus reflector, light intensity is more even relatively, but very high to the tracking accuracy requirement, and the length of focal length is subjected to the restriction of the sunlight angle of divergence (+/-0.26 degree); The 2nd, when adopting weak point focal length speculum, light intensity is seriously inhomogeneous, but lower to the tracking accuracy requirement, needs the secondary optical system of complexity this moment, and with the uniformity of raising light intensity, but its effect is limited, system complex.
By test as can be known, the short more Energy distribution of focal length is inhomogeneous more, and when focal length during less than diameter, the inhomogeneities of light intensity can not be used (because having bigger rugged change).Focal length is long more, because the edge spillover that the angle of divergence of sunlight causes is serious more, its spill-out is directly proportional with focal length.This characteristic can be reflected on the precision of tracker simultaneously, that is to say, focal length is long more, and is high more to the required precision of tracker.
The utility model content
The purpose of this utility model is to solve the problems referred to above that prior art exists, and provides a kind of light distribution evenly, tracking accuracy is required the not high again solar receiver that is used for reflection concentration type.
The purpose of this utility model is achieved in that a kind of solar receiver that is used for reflection concentration type, be used with parabolic reflector formula concentrator, it comprises a heat radiation substrate and is installed in suprabasil at least one solar cell of this heat radiation, be characterized in, the surface of described solar receiver is curved surface or approximate curved surface, and its focus overlaps substantially with the paraboloidal focus of reflection-type beam condenser.
The curved surface of described solar receiver is similar to sphere.
Described solar receiver is made up of the monoblock battery that is made into curved surface.
Described solar receiver is formed whole curved surface by a plurality of baby battery serial or parallel connections that are made into curved surface.
Described solar receiver is formed approximate curved surface by a plurality of planes baby battery serial or parallel connection.
Baby battery in the described solar receiver can tilt, and can form the optimum reception curved surface by the angle of inclination of regulating each baby battery.
The solar receiver that is used for reflection concentration type of the present utility model is a curved surface owing to receiving plane, even burnt torch is very short, Energy distribution is also very even, its uniformity surpasses the situation of any long-focus, when focal length in short-term, because the edge that the sunlight angle of divergence causes overflows also corresponding minimizing, the required precision to tracker has simultaneously also reduced.
