Abstract
A back surface contact type solar cell having a first conductivity type region and second conductivity type region formed alternately at one surface of a semiconductor substrate, includes an electrode for first conductivity type arranged on the first conductivity type region, and an electrode for second conductivity type arranged on the second conductivity type region. The back surface contact type solar cell includes a first non-connection region between electrodes for second conductivity type adjacent in an aligning direction of the first conductivity type region and the second conductivity type region, impeding electrical connection with the electrode for first conductivity type, and a second non-connection region between electrodes for first conductivity type adjacent in the aligning direction, impeding electrical connection with the electrode for second conductivity type . A back surface contact type solar cell with a wiring board, a solar cell string, and a solar cell module are also provided.
