Novel busbar-free cell design for shingled solar modules

South Korean scientists have fabricated a busbar-free solar cell for shingled modules that uses 60% less silver than its busbar counterparts. A module with the new cells had almost the same performance as a reference shingled panel built with a conventional cell design.Scientists at Sungkyunkwan University (SKKU) in South Korea have developed a busbar-free solar cell design for shingled solar modules to reduce silver (Ag) paste consumption. They designed the cell with a busbar-free electrode pattern, with the electrodes consisting of Ag fingers and busbars on the front side and aluminum (Al) electrodes ...
