Solar panel manufacturers of solar power device provides the work

Zhongshan solar panels - Guangdong energy technology co. , LTD. , of photovoltaic solar panels are widely used in the production of diffusion method. 1. Source diffusion system knot used silicon solar panels production source diffusion method basically has the following kinds. (

solar panel manufacturers in guangdong zhongshan energy technology co. , LTD. Pay attention to the spread of the methods commonly used in the production of photovoltaic solar panels. 1. Source diffusion junction silicon solar panels used in the production of main source diffusion method is as follows. ( 1) Coating is the source of the diffusion source diffusion coating can be divided into simple source diffusion coating and silica coating latex source diffusion. ( 1) Simple diffusion coating: 1 ~ 2 drops of phosphorus pentoxide ( P2O5) Or boron trioxide (

B2O3) Made from dilute aqueous solution ( Or ethanol) , drop in P or N type silicon surface, as a source of impurity and silicon reaction phosphorus and boron silicate glass. Deposited on silicon on the surface of the impurity elements in diffusion temperature diffusion to silicon, forming a p-n junction or N - P junction. ( 2) Silica rubber latex is the hydrolysis of organic siloxane polymer, which can be dissolved in organic solvents such as ethanol formation has certain viscosity of the solution. In 100 ~ 400 ℃ after baking, can form amorphous silica. Silica rubber latex can pass to add water and anhydrous ethanol ethyl silicate and hydrolysis, or join after introducing silicon tetrachloride acetic acid ethanol to obtain. The silica rubber latex source can dissolve impurities such as phosphorus pentoxide or boron trioxide and ethanol diluted to gain. ( 2) The spread of the liquid source liquid diffusion source including phosphorus oxychloride liquid source diffusion and boron diffusion source. It will by way of carrier gas impurities into the diffusion furnace, diffusion. Relevant tags: makers of solar panels, solar panels, high efficiency solar panels, guangdong energy technology co. , LTD
