UNSW Solar phosphorus (POCl) diffusion for silicon solar cells

Views:2854|Rating:5.00|View Time:2:21Minutes|Likes:23|Dislikes:0Tube diffusion is the de facto standard way to form the p-n junction in industrial silicon solar cells. The majority of silicon solar cells are produced from p-type silicon and consequently, a phosphorus diffusion is used to create a heavily doped n-type layer at the surface. This is done by placing the silicon wafer […]

Soldering Sunpower Maxeon Solar Cells

Views:11261|Rating:4.91|View Time:5:59Minutes|Likes:170|Dislikes:3 I show you how to solder Sunpower’s Maxeon solar cells. These cells are very flexible, attractive, and supposedly efficient. All the solder points are on the back of the cell, which makes the connections very easy. The price per watt of these cells is higher than some. The time saved is HUGE! That […]
