Description
Technical Field
The utility model relates to a photovoltaic crystal silicon subassembly, specifically speaking are large tracts of land photovoltaic crystal silicon subassembly.
Background
The photovoltaic crystal silicon assembly is a module for converting light energy into electric energy through a crystalline silicon PN junction semiconductor, and is called a photovoltaic cell for short. Photovoltaic crystal silicon subassembly is at present widely used in fields such as large-scale ground power station, roofing, boats and ships, aviation.
The conventional packaging process of the photovoltaic crystalline silicon component comprises the following steps: firstly, a piece of 157 x 157mm battery piece is serially connected and welded into a string by adopting a tinned copper strip, and then the string and the string are connected by using a wider confluence strip to form an array battery pack, so that the packaging of the electrical appliance part of the assembly is completed. The packaging and welding process needs to be completed by using a plurality of special automatic welding devices and welding materials.
Gaps of 2-3 mm are reserved between each small battery piece, and the power generation conversion efficiency of the single-block assembly is low. And moreover, the energy consumption of the welding equipment is high, the soldering flux in the welding material can chemically react with the EVA of the packaging material, and the service life of the assembly is shortened. In order to improve the conversion efficiency of the monolithic assembly, reduce the production energy consumption, improve the efficiency and reduce the cost, the gaps among the battery pieces need to be reduced, and the area ratio of the power generation battery pieces needs to be improved.
In the conventional battery assembly, welding strips, soldering flux and a welding machine are used for welding and connecting one sheet, and then typesetting, laminating and packaging are carried out.
Disclosure of Invention
The utility model aims at overcoming the not enough of existence among the prior art, provide one kind can save welding process, can improve conversion efficiency and improve production efficiency's large tracts of land photovoltaic crystal silicon subassembly.
According to the technical scheme provided by the utility model, the large-area photovoltaic crystal silicon component comprises a bottom plate, a battery piece, a bus bar and a conductive circuit; two slice battery pieces about installing on the bottom plate, the width of battery piece is less than the width of bottom plate, and the printing has the conducting wire on every battery piece, installs between two battery pieces and converges the area, the length of battery piece is 950~955mm, and the width of battery piece is 950~955 mm.
The bottom plate is made of glass.
The distance between the two battery pieces is 12-18 mm.
The distance between the edge distance of the battery piece and the edge of the corresponding bottom plate is 14-16 mm.
The utility model discloses a structure is very simple, the utility model discloses saved welding process, improved conversion efficiency and improved production efficiency.

Detailed Description
The present invention will be further described with reference to the following specific embodiments.
The utility model discloses a large-area photovoltaic crystal silicon assembly, which comprises a bottom plate 1, a battery piece 2, a convergence belt 3 and a conductive circuit 4; two slice batteries 2 about installing on bottom plate 1, the width of battery piece 2 is less than bottom plate 1's width, has printed conducting wire 4 on every slice battery 2, installs between two slice batteries 2 and converges and take 3, the length of battery piece 2 is 950~955mm, and the width of battery piece 2 is 950~955 mm.
The bottom plate 1 is made of glass.
The distance between the two battery pieces 2 is 12-18 mm.
The distance between the edge distance of the battery piece 2 and the edge of the corresponding bottom plate 1 is 14-16 mm.
Because must leave 2~3 mm's space between adjacent two battery pieces 2 in the photovoltaic crystal silicon subassembly, to the photovoltaic crystal silicon subassembly of the same area, the clearance area among the photovoltaic crystal silicon subassembly of prior art is great, and the utility model discloses a clearance area among the photovoltaic crystal silicon subassembly is less, the utility model discloses a reduce clearance area, promoted the conversion efficiency that generates electricity.
The utility model discloses a 2 the large tracts of land battery pieces 2 have just accomplished among the prior art dozens of battery pieces 2 series welding and have just can reach the electricity generation conversion volume together, so, the utility model discloses can make photovoltaic crystal silicon subassembly's structure become very simple. The utility model discloses saved welding process in during manufacturing, directly adopted 2 battery pieces 2 of large tracts of land to typeset the encapsulation, improved production efficiency.
