Manufacture of photovoltaic device

Abstract

Abstract PURPOSE:To manufacture a photovoltaic device which does not result in unnecessary power loss and assures sufficient exposure to light by forming a light transmitting part without rear surface metal electrode in such a way as not gives damage to the joint of photoelectric converting regions. CONSTITUTION:With electrical connection of rear surface metal electrode 6a and photosensitive surface electrode 2b, division of semiconductor films 5a, 5b and rear surface metal electrodes 6a, 6b is carried out. As a result, the rear surface metal electrode 6a of the adjacent photoelectric converting regions 7a, 7b and the photosensitive surface electrode 2b are coupled at the joint 9 and the photoelectric converting regions 7a, 7b are electrically connected in series. Next, the coupling part 9 of the photosensitive surface electrodes 2a, 2b of photoelectric converting regions 7a, 7b and rear surface metal electrodes 6a, 6b are covered with a protective film 10. Thereafter, the rear surface metal electrodes 6a, 6b are selectively removed with the photolithography technology and a light transmitting part 13 is formed. Thereby, the light transmitting part allows direct transmission of light, avoiding requirement of light transmission for the rear surface metal electrode.
