| Abstract: | A new two step diffusion manufacturing technology of high
temperature steady resource diffusion followed by low temperature constant quantity diffusion is
presented for back surface fields Si solar cells. By comparing with the ordinary one step steady
resource diffusion manufacturing technology, the short circuit current I sc is increased by
about 20 %. The open circuit voltage V oc is also improved obviously and photoelectric
conversion efficiency increased by about 4%. |
