Abstract
One of the key features of high efficiency HJT-solar cell manufacturing is the front side contact. Conventional metallization pastes contains a large amount of silver as the current conducting phase providing low finger resistivity as well as low specific contact resistance to the ITO film. Two intrinsic disadvantages can be figured for silver pastes: (i) the price per gram silver and (ii) shading losses on cell level. In this study, a transparent polymer paste was developed based on an intrinsic conductive polymer. A new front side contact paste for hetero junction solar cells is presented which reduces the cost and simultaneously reduces shading of the front side grid.
