A novel topcon perovskite tandem solar cell

Abstract

The utility model relates to the field of solar cell especially relates to a novel TOPcon perovskite laminated solar cell, including from top to bottom the connection of front side screen printing metal wire layer, front side sandwich structure transparent conductive protection film layer, hole transport layer, SAM interface layer, perovskite light absorption layer, electron transport layer, interface conductive layer, TOPcon battery multilayer film structure layer and back screen printing metal wire layer. The utility model front side adopts sandwich structure's transparent conductive film layer, improves water vapor resistance, uses linear airflow plasma sputtering to make sandwich's transparent conductive film layer, first layer and third layer use low parameterization high carrier mobility's transparent conductive oxide, use amorphous and high water vapor resistance's transparent conductive oxide in the middle, use linear airflow plasma sputtering process to prepare hole transport layer, prevent water vapor or plating medicine water to pass through film layer and enter perovskite light absorption layer to cause material's cleavage and the reduction of efficiency.
