Uppsala University and the division of Solar Cell Technology at the Ångström laboratory are coordinating SITA.

The thin film solar cell research started in 1994, but since 2020 the research has been organized as its own division, which consists of more than 20 persons; professors, researchers, Postdocs, PhD students and engineers from Electronics, Physics, Chemistry and Materials Theory, all with a strong interest in solar cell science.

The Ångström laboratory clean-room has a full laboratory facility for fabrication and material characterization of solar cell materials and solar cells, including evaporation and sputter equipment, ALD, laser and mechanical patterning and electron microscopy, as well as X-ray-based methods. Electrical measurements are made in a dedicated solar cell characterization lab, including JV, EQE and CV measurements.

The main research interest is in the chalcogenide solar cells based on CIGS, CZTS and inorganic chalcogenide perovskites, such as ZrBaS3. Of relevance for the SITA project, the division has pioneered work on the influence of Na in CIGS solar cells, passivated back contact and ultra-thin solar cells, as well as well-recognized research on Ag in CIGS, especially targeting high bandgap devices.
