Abstract
Provided is a busbar-free interdigitated back contact (IBC) solar cell and an IBC solar cell module. The IBC solar cell includes a semiconductor substrate, finger electrode lines and conductive lines. The finger electrode lines include first finger electrode lines and second finger electrode lines that are alternately arranged on the semiconductor substrate. The conductive lines include first conductive lines and second conductive lines that are alternately arranged. The first conductive lines are connected to the first finger electrode lines and spaced apart from the second finger electrode lines. The second conductive lines are connected to the second finger electrode lines and spaced apart from the first finger electrode lines.
