METHOD FOR FABRICATING BACK ELECTRODE TYPE SOLAR CELL, AND BACK ELECTRODE TYPE SOLAR CELL

摘要

A method for fabricating a back electrode type solar cell include the steps of applying a solution including a compound containing first conductivity type impurities, titanium alkoxide, and alcohol to a surface of a first conductivity type silicon substrate, and forming a light-receiving face diffusion layer and an anti-reflection film by subjecting the solution to heat treatment in a nitrogen atmosphere. There is also provided a back electrode type solar cell including a light-receiving face diffusion layer having a sheet resistance greater than or equal to 100 Omega/ and less than 250 Omega/.
