Indium tin oxide is the preferred material for transparent conductive oxide (TCO) layers in heterojunction solar cells, but researchers are studying the use of indium free materials to reduce the cost of this layer. The reflectivity and conductivity of ITO make it a better contact layer and outer layer for HJT solar cells.
Nonetheless, the indium contained in ITO is a rare metal with limited reserves and mining capacity, resulting in higher production costs . This poses a significant hurdle to the future expansion of heterojunction solar cell industry.
