Canadian Solar was one of the first companies to introduce PV cell and module technologies that later became the industry mainstream, such as bifacial modules (back in 2010), modules with larger-format wafers (up to 210 mm) and, nowadays, N-type high-efficiency cells and modules. Since 2019, CSI Solar has been developing N-type TOPCon (Tunnel Oxide Passivated Contacts) technologies, and is now launching a diversified TOPCon module portfolio covering both 182 mm and 210 mm cells, single-glass and double-glass encapsulation, and various module sizes and power outputs to satisfy different application scenarios.
N-type solar cells have a slightly different construction compared to traditional p-type solar cells. The main difference lies in the doping of the semiconductor material used in the cell.
Here is a general overview of the construction of an n-type solar cell:
Solarity has secured a decent quantity of Topcon N-type modules in the warehouse. Currently, Solarity can provide the market with 565W bifacial Topcon modules as this power class is in the most demand on the market. Also, Solarity will soon secure a higher power class of Topcon modules for C&I projects, either in regular or bifacial types. The power class will be 656 W and above as Canadian Solar will provide up to 690 W modules.
