Abstract: A method for manufacturing a solar cell, includes forming an oxide layer on first surface of a single crystalline silicon substrate; forming a poly crystalline silicon layer doped with a first dopant having a first conductive type on the oxide layer; diffusing a second dopant having a second conductive type opposite to the first conductive type into a second surface of the single crystalline silicon substrate thereby forming a diffusion region; forming a first passivation layer on the poly crystalline silicon layer; forming a second passivation layer on the diffusion region; forming a first electrode connected to the poly crystalline silicon layer by printing a first paste on the first passivation layer and firing through; forming a second electrode connected to the diffusion region by printing a second paste on the second passivation layer and firing through.
