How to connect electrodes between back-content solar cells

摘要

PURPOSE: A method for connecting an electrode between back-contact solar cells is provided to increase energy conversion efficiency by preventing module efficiency from reducing due to a front electrode of a solar cell. CONSTITUTION: Back-contact solar cells(209, 210) are formed into a p-n junction structure. A cathode electrode and an anode electrode are placed on the back side of the solar cell. An electrode pattern(211) on the back-contact solar cells is over 5. An interconnection ribbon(206) connects the back-contact solar cells in series.
