These startups use perovskites to create highly efficient and low-cost solar cells.
1
Oxford PV
Country: UK | Funding: $152.2M
Oxford PV develops perovskite tandem cell technology - solar cells that consist of two components: one perovskite and the other silicon. Traditional silicon solar cells absorb light in the red part of the spectrum, while perovskite absorbs light in the blue part. Thus, a tandem cell captures more sunlight than a single cell can, and therefore generates more energy. All this without changing the size (area) of the solar cell. Oxford PV's proprietary perovskite technology is designed to work with standard solar panels. The company has its own manufacturing facility and sets new world records for perovskite cells efficiency almost every year.

Tandem PV
Country: USA | Funding: $84.4M
Tandem PV produces tandem photovoltaic systems that use perovskite, which captures wavelengths of light that conventional silicon solar panels inefficiently convert into electricity. Their technology delivers significantly higher power output with the same panel area and similar cost per watt. Tandem PV panels have an enhanced durability suitable for long-term use, as demonstrated by accelerated testing showing degradation of less than 1% per year. The company is also building a robust patent portfolio in core perovskite layer technologies, system design and durability metrics to protect and expand these advantages as production scales.
3
Swift Solar
Country: USA | Funding: $50.4M
Swift Solar is developing lightweight, flexible, and highly efficient solar panels based on perovskite tandem semiconductors. The company says it has improved perovskite stability by >100x: it's cells can operate over 3,000+ hours with no degradation. Swift's intellectual actives include unique patent-protected solar cell materials, architectures and manufacturing processes for high-performance and stable perovskite products. The company has own manufacturing facility in the USA
4
SoFab Inks
Country: USA | Funding: $500K
SoFab Inks' technology improves perovskite panels by replacing expensive photovoltaic materials with a liquified “ink.” This more cost-effective, high-performance liquid can be deposited as one of the conductive layers of a solar cell called charge transport layers that allow electrons to move and produce electricity.
5
Perosol
Country: Germany
Perosol is developing lightweight, flexible and sustainably printed perovskite solar cells. The company intends to build a large-scale printing facility that will be able to produce several kilometers of solar cells per day.
