Meyer Burger and CSEM PV Center are establishing the Swiss-Inno HJT Project that will include a pilot line and development program to produce low-cost Heterojunction silicon solar cell technology (HJT).
The Swiss-Inno HJT Project is being provided with around US$11.25 million over 3 years in R&D funding. HJT development started in 2008 with Roth and Rau and the Photovoltaics Laboratory of the IMT at EPFL. Roth and Rau has since become a subsidiary of Meyer Burger.

The HJT project overall includes Meyer Burger group members Roth & Rau Research, PASAN and the Meyer Burger competence centre in Thun as well as CSEM’s PV-center.
Key to the Heterojunction technology is the deposition of ultra-thin layers of amorphous on both sides of monocrystalline wafers that offers bi-facial capabilities for higher conversion efficiencies.
