Bifacial modules

Several cell structures have been presented that can operate with bifacial illumination. By encap­sulation with a transparent backsheet (usually plastic one although glass is also possible), bifacial modules offering increased power output per unit cell area can be produced without technology changes. In spite of their potential, their presence in the market is very small for the moment. Modules with back contact cells

Back contact cells are interconnected without tabs by soldering them to a layer with the connection paths printed, similar to PCB practice in electronic circuits. These experimental designs offer simplified module fabrication and enhanced visual appeal.
