Abstract
The invention relates to a solar battery component, which comprises a plurality of groups of battery packs which are mutually connected by interconnection strips; each battery pack comprises a piece of N-type solar battery plate and a piece of P-type solar battery plate, wherein illuminated surfaces of the N-type solar battery plate and the P-type solar battery plate in the battery pack are connected by a narrow interconnection strip; the adjacent battery packs are arranged in a mode that the N-type solar battery plate and the P-type solar battery plate are adjacent; and backlight surfaces of the adjacent N-type solar battery plate and P-type solar battery plate between the battery packs are connected by an interconnection strip with the big sectional area. The electric current collecting density is increased by reducing the sectional areas of the interconnection strips of the illuminated surfaces, namely, reducing the light shading area and increasing the sectional areas of the interconnection strips of the backlight surface so as to lead more sunlight to enter the battery to realize photoelectricity conversion; the interconnection strips adopted by the illuminated surfaces and the backlight surfaces are made of different ingredients so as to ensure the resistance connecting mode, wherein the resistance is as low as possible, therefore, more electric currents can be collected.
Description
Technical field
The present invention relates to a kind of solar module.
Background technology
For crystal silicon solar battery component, adopt a zinc-plated copper strips to connect both positive and negative polarity between the battery sheet usually, the interconnecting strip of sensitive surface and shady face is measure-alike, as shown in Figure 1.In order to promote photoelectric conversion efficiency, the interconnecting strip of sensitive surface can require to reduce as far as possible the shading area, the interconnecting strip of shady face can increase electric current collection and adopt the big interconnecting strip of sectional area, occurs T shape interconnecting strip product on the market, the narrow and backlight face width of promptly zinc-plated copper strips sensitive surface part.This T shape interconnecting strip is owing to the complexity of processing technology in enormous quantities, and its price is also than the common interconnecting strip height in market.
Summary of the invention
Technical problem to be solved by this invention is: a kind of solar module is provided, improves the conversion efficiency and the power output of solar module.
The technical solution adopted for the present invention to solve the technical problems is: a kind of solar module, comprise that many groups are by the interconnective battery pack of interconnecting strip, each battery pack comprises a N type solar battery sheet and a P type solar battery sheet, N type solar battery sheet in the battery pack is connected with narrow interconnecting strip with the sensitive surface of P type solar battery sheet, arrange by the N type solar battery sheet mode adjacent between the adjacent cell group, and the adjacent N type solar battery sheet between battery pack is connected with the big interconnecting strip of sectional area with the shady face of P type solar battery sheet with P type solar battery sheet.
The invention has the beneficial effects as follows: promptly reduce the shading area by reducing sensitive surface interconnecting strip sectional area, the sectional area that increases the shady face interconnecting strip increases electric current collection density, makes more sunlight enter battery and opto-electronic conversion takes place; The composition of the interconnecting strip that sensitive surface and shady face adopt is chosen different, guarantees that alap resistance connected mode is collected more electric current.
