Researchers from the University Grenoble Alpes, CEA, Liten, and Campus INES have published a study demonstrating a significant 77.2% reduction in indium consumption for silicon heterojunction (SHJ) solar cells. The team achieved this by optimizing transparent conductive oxide (TCO) and dielectric layers, incorporating thin 15 nm ITO/SiNx coatings on the front and 30 nm IMO:H on the rear. The cells exhibited high UV and heat stability, with minimal efficiency loss below 0.1%. Reliability tests under UV and damp heat conditions revealed better durability than standard cells. These advancements showcase potential for cost-effective solar technology.
