Abstract
The invention discloses a photovolatic concentrating receiver with a secondary baffle board, comprising a light-transmitting tube, a battery assembly, insulated liquid and a secondary baffle board. The secondary baffle board is arranged above or below the light-transmitting tube; and the battery assembly forms a prismatic shape and is arranged in the light-transmitting tube in which the insulated liquid is arranged. In the invention, primary light-focusing light which is arranged around focus spots and is not irradiated on the battery assembly is reflected into the light-transmitting tube by using the secondary baffle board and the battery assembly which is arranged in the light-transmitting tube and forms a prismatic surface can fully receive partial light-focusing light, so that full utilization of the light-focusing light can be realized. Meanwhile, the insulated liquid flowing through the light-transmitting tube can effectively cool a solar battery and is beneficial to ensuring the high-efficiency work of the solar battery.
Description
Technical field
The invention belongs to the concentrating photovoltaic power generation technical field.Relate to a kind of concentration photovoltaic receiver.
Background technology
Solar photovoltaic technology is the solar utilization technique that directly transform light energy of the sun is become electric energy, have plurality of advantages such as cleaning, safety, noiseless, simple in structure, easy installation, though solar energy power generating gets most of the attention, but because too high cost also fails fully to come into the market at present.Because concentrator solar cell has higher efficient than common solar cell usually, therefore one of effective way that reduces the solar cell cost of electricity-generating is to adopt concentrator solar cell, to reduce the required cell area of given power, partly replace expensive solar cell with comparatively cheap concentrator.But no matter be to adopt the point focusing or the concentrator of line focus, the light intensity of focal spot position all is uneven, a little less than the middle strong both sides.Uneven light intensity can cause the decline of the inhomogeneous of solar cell working temperature and battery fill factor, curve factor, thereby causes the decline of whole system efficient.Therefore be to obtain light distribution relatively uniformly, then can only arrange battery, can't make full use of the light that converges at focal spot place, cause the waste of energy in the center of focal spot at solar battery surface.
Summary of the invention
The objective of the invention is to overcome the deficiencies in the prior art, a kind of concentration photovoltaic receiver that has the secondary reflection plate is provided.
Technical scheme of the present invention is summarized as follows:
A kind of concentration photovoltaic receiver that has the secondary reflection plate, comprise light-transmission tube, battery component and iknsulating liquid, also comprise the secondary reflection plate, the secondary reflection plate be arranged on light-transmission tube above or below, battery component is formed prism-shaped and is arranged in the light-transmission tube, is provided with iknsulating liquid in the light-transmission tube.
Preferred 3～20 of prismatic number of sides.
The battery component of forming the side of prism-shaped can directly be connected and composed or be connected and composed by solar cell and substrate by solar cell.
The geometry of secondary reflection plate is V-type groove or U type groove or the groove type paraboloid of being made up of 2～20 faces.
A kind of concentration photovoltaic receiver that has the secondary reflection plate of the present invention, can utilize the secondary reflection plate that an optically focused light that does not shine battery component around the focal spot is reflexed in the light-transmission tube, and battery component is formed prism-shaped and is arranged on and can fully receives this part secondary condensation light in the light-transmission tube, realized making full use of to optically focused light, the iknsulating liquid that flows through light-transmission tube simultaneously can effectively cool off solar cell, helps to guarantee the high efficiency work of solar cell.
