Abstract
The disclosure provides an electrode structure of a back contact cell, a back contact cell, a back contact cell module, and a back contact cell system. The electrode structure includes: first fingers, configured to collect a first polarity region; second fingers, configured to collect a second polarity region; a first busbar, disposed on a side of the back contact cell close to a first edge and connected to the first fingers; first pad points; and first connection electrodes, respectively connected to the first busbar and the first pad points. A distance between each of the first pad points and the first edge is greater than a distance between the first busbar and the first edge. The electrode structure can improve the reliability, reduce the costs, increase the product yield, and ensure excellent photoelectric conversion efficiency.
