Hi-BITS at PVSEC-35: Advancing Semi-Transparent Solar Technologies

Numazu, Japan – 14 November 2024

Angelica Thomere, researcher at the International Iberian Nanotechnology Laboratory (INL), represented Hi-BITS project at the 35th International Photovoltaic Science and Engineering Conference (PVSEC-35), held from 10 to 15 November 2024 in Numazu, Japan.

Her presentation, entitled “Transparent back contacts for semi-transparent micro-striped chalcopyrite Cu(In,Ga)Se₂ solar cells for window applications”, showcased cutting-edge research developed under the Hi-BITS initiative. The study, co-authored by N. Rodrigues, V. Kumar, P. Anacleto, and project coordinator S. Sadewasser, focuses on enabling transparency and light management in thin-film solar cells, targeting integration into energy-generating windows.

This innovative work aligns with the Hi-BITS mission to pioneer high-efficiency bifacial and semi-transparent thin-film chalcogenide solar cells, aiming for novel applications in building integration and sustainable energy solutions.

The development of transparent back contacts represents a key step towards realising aesthetically integrated photovoltaics without compromising performance.

Participation in PVSEC-35 provided an excellent platform for disseminating the project’s scientific advancements, strengthening international collaborations, and engaging with the broader photovoltaic research community.
