Abstract: A method for fabricating back-contact type solar cells is provided. The method comprises forming a plurality of n-type doped zones, a plurality of p-type doped zones, and a back anti-reflection layer on a back surface of a semiconductor substrate. The lead-containing conductive paste may pass through the back anti-reflection layer and connect to the n-type doped zones and the p-type doped zones thereby being regarded as n-type electrodes and p-type electrodes.

Abstract: A solar cell includes a substrate. The substrate has a light-receiving surface and a back surface opposite to the light-receiving surface. The substrate includes plural trenches formed on the back surface. The solar cell includes plural n-type diffusion areas and plural p-type diffusion areas alternately disposed on the back surface and the surface of the trenches. The possibility of recombination of the electron-hole pair while moving can be reduced because of the trenches, which are formed in the substrate.
