Abstract
The invention relates to a photovoltaic assembly including an aluminum frame and an assembly main body arranged on the aluminum frame. The assembly main body includes a piece of tempered glass, a first layer of encapsulation material, a battery group, a second layer of encapsulation material and a backboard. The tempered glass is agglutinated with the battery group through the first layer of encapsulation material. The battery group is agglutinated with the backboard through the second layer of encapsulation material. The battery group is formed through parallel connection of a plurality of mono-like cell groups and the mono-like cell groups are formed through serial connection of a plurality of mono-like cells. Compared with the prior art, the photovoltaic assembly has the advantages of being high in conversion efficiency and low in cost.
Description
Technical field
The present invention relates to a kind of solar components, especially relate to a kind of photovoltaic module.
Background technology
Since solar module came out, high efficiency and low cost were two main competition spots always, and crystalline silicon relies on the efficient stable of its battery always in occupation of absolute advantage as current topmost solar cell material.
Monocrystalline silicon generally adopts Czochralski method (CZ method) to make, single crystal seed with particular crystal orientation is carried out seeding, obtain the silicon single crystal rod in target crystal orientation through rotary pulling, products obtained therefrom only contains a crystal grain, have the characteristics such as low defective, high conversion efficiency, but the method is high to raw material and operation requirements, and single feeds intake fewly, and product cost is higher; Polysilicon mainly is to adopt directional freeze method to make, and the single inventory is large, has the characteristics such as easy to operate, low adult, but the conversion efficiency of polysilicon solar cell is than the low approximately 1.5-2% of monocrystalline silicon battery.
Except traditional polysilicon and monocrystalline silicon, the solar energy dealer just is being devoted to develop a kind of new architecture that has monocrystalline and polycrystalline advantage concurrently at present: " class monocrystalline " be technology (Mono-like).The core of class single crystal technology is the monocrystalline ingot casting technology, adopts single crystal-like that casting ingot process produces even the product of full monocrystalline, and the advantage of monocrystalline silicon and polysilicon is harmonious.Compared to polycrystalline, the quasi-monocrystalline silicon crystal boundary is few, and dislocation density is low; Compare with monocrystalline silicon piece, the photo attenuation of accurate single crystal battery is low about 1/4～1/2, and it is large to throw furnace charge, and production efficiency is high, and slice process is simple, and cost is low.
The domestic producer that is engaged in class monocrystalline research and produces has: Poly association is prosperous, sunlight brightness, brilliant Australia, Ying Li etc.At present, the conversion efficiency of class single crystal battery sheet surpasses the authentication that the solar components producers such as 18%, Ying Li, middle electricity be electric have passed through class mono-crystal component bring to power, and the class mono-crystal component is introduced to the market.
Summary of the invention
