NOVELTY - This utility new type claims a one double-side thin film photovoltaic cell, include from lower to upper in turn set with a substrate, first transparent electric conduction film, P type photovoltaic absorption layer thin film, N type cadmium sulphide film layer and second transparent electric conduction film, a substrate is high molecular thin film material, a first transparent electric conduction film and second transparent electric conduction film is graphene thin film through physical chemical absorbing method of treatment. This utility new type using a modified graphene thin film new material to replace a transparent electric conduction film and metal electrode layer in the conventional CIGS thin film photovoltaic cell, through double-side high light transmittance, high conductivity of graphene thin film, valid improve photoelectric conversion efficiency of thin film photovoltaic cell.
