About

Evolar is leading the evolution in solar by commercializing the next generation of photovoltaics by offering a solution that enables industrial-scale production of perovskite tandem solar cells.

Evolar was founded in 2019 and boasts one of the industry’s most experienced teams of solar cell experts. We have more than 30 years of experience in solar cell production and have already successfully commercialized thin-film solar cell technology. Evolar has quickly established itself as a key player in the race to commercialize perovskite tandem solar cell technology with our PV Solar Booster technology and PV Solar Booster Line production solution.

Located in Uppsala, Sweden, Evolar enjoys a close relationship with Uppsala University, Sweden’s oldest and most prestigious university, and home to one of the country’s leading solar cell research clusters.
