Back junction solar cell, back junction solar cell with wiring board, solar cell string and solar cell module

摘要

A back junction solar cell in which a first conductivity type region (111) and a second conductivity type region (112) are alternately formed on one surface of a semiconductor substrate (101), the first conductivity type region (111 ) Having a first conductivity type electrode (121) and a second conductivity type electrode (122) installed on the second conductivity type region (112), the first conductivity type region ( 111) and the second conductivity type region (112) in a region where the second conductivity type electrode (122) adjacent in the arrangement direction is prevented from being electrically connected to the first conductivity type electrode (121). A second non-connection region (141) and a second conductivity type electrode (121) adjacent to each other in the arrangement direction of the first conductivity type region (111) and the second conductivity type region (112). The second region which is an area where electrical connection with the conductive type electrode (122) is hindered Back junction solar cell has a connection region (142), a back junction solar cell with a wiring substrate, a solar cell string and a solar cell module.
