High photovoltaic-conversion efficiency solar cell, method for manufacturing the same, solar cell module, and photovoltaic power generation system

摘要

To Provide a back contact type solar cell with high photovoltaic-conversion efficiency which can be easily manufactured with good yield at low cost. The high photovoltaic-conversion efficiency solar cell of the present invention includes on a back surface, as a non-light receiving surface, of a first conductive type semiconductor substrate: a first conductive type diffusion layer where first conductive type impurities are diffused; a second conductive type diffusion layer where second conductive type impurities are diffused; and a high resistive layer or an intrinsic semiconductor layer formed between the first conductive type diffusion layer and the second conductive type diffusion layer.
