HETERO JUNCTION TYPE BACK CONTACT CELL AND PHOTOELECTRIC CONVERSION DEVICE

摘要

A hetero junction type back contact cell (10) is provided with: a first conductivity-type or second conductivity-type semiconductor substrate (1); a first conductivity-type amorphous semiconductor film (3) and a second conductivity-type amorphous semiconductor film (5), which are provided on one side of the semiconductor substrate (1); a first electrode (11) on the first conductivity-type amorphous semiconductor film (3); and a second electrode (12) on the second conductivity-type amorphous semiconductor film (5). The distance between the centers of the adjacent electrodes closest to each other is 1-3.5 mm, said electrodes having a same polarity.
