Indium Tin Oxide is the preferred material for the transparent conductive oxide (TCO) layer of the heterojunction solar cell, but researchers are investigating using indium-free materials that will reduce costs for this layer.
High-mobility indium oxide (IO:H) is used in silicon heterojunction solar cells. Cells with IO:H have excellent EQE but low FF because the IO:H/Ag contact is poor. We propose IO:H/ITO bilayers for low contact resistance and high mobility. Solar cells with IO:H/ITO bilayers outperform cells with pure IO:H or ITO layers.

Heterojunction technology is currently a hot topic actively discussed in the silicon PV community. Hevel recently became one of the first companies to adopt its old micromorph module line for manufacturing high-efficiency silicon heterojunction (SHJ) solar cells and modules.
Anti-Burstein-Moss effect of TTO was found, which is mainly related to the changes of stress in the film. TTO was applied to SHJ solar cells to obtain efficient indium-free SHJ solar cells. TTO-based indium-free SHJ solar cell achieved an efficiency of 25.15 % with a certified efficiency of 25.10 % (274.3 cm 2).
PV parameters of SHJ solar cells with indium-free transparent conductive oxides in the previous published work. TTO as an alternative to indium-based TCO material, must have better sustainability for future scale-up of indium-free SHJ solar cells. The host material SnO 2 of TTO is naturally abundant.
However, high cost of indium-based TCO films is not conducive to mass production of the SHJ solar cells. A variety of indium-free or indium-less TCOs are explored and utilized presently. Here, SnO x films are deposited by reactive plasma deposition (RPD) with metal tin as the evaporation source.
ITO layers are commonly used in SHJ cells as transparent conductive oxide layers, and it is very important to optimize their properties, in particular for the production of bifacial HJT solar cells. An investigation of the various stoichiometric contents of ITO sputter magnetron targets has been carried out at Hevel’s R&D Center.
