Epishine manufactures low-power printed solar cells for sensors, electronic price tags, locks and other electronics. These solar cells require no sunlight to operate, meaning they can be used with standard room lighting, such as ambient and artificial light from lamps and other sources. Depending on ambient conditions they generate approximately 22 μW/cm² at 500 lux. They are flexible and can withstand up to 1 million bends without degradation, and are available in variety of sizes suitable for variety of applications. Key advantage is that they are composed entirely of organic materials and that os why - fully recyclable and certified to RoHS (no exceptions) and REACH. The company uses roll-to-roll printing technology for production.

Arinna builds ultrathin solar panels specifically for spacecraft. Its technology is based on a new material - transition metal dichalcogenides that are atomically thin semiconductors. This technology allows for extremely flexible cells that the company claims are cheaper, more durable than legacy space solar panels and 32% more efficient. Arinna’s technology also won’t require protective coverings, will last 15 years on orbit, and can be delivered within weeks. The company expects to have its first products being tested on orbit before the end of 2026. After qualifying their photovoltaics in space, the company hopes to build a facility that can mass produce the stuff at megawatt scale in 2028.

Kardinia Energy is a manufacturer and supplier of printed solar modules that use carbon-based semi-conducting polymers printed on recyclable PET plastic (materials that are highly abundant and do not require the energy-intensive manufacturing processes associated with silicon solar panel production). The printed solar modules weigh 300g per square meter and utilise easily sourced, non-silicon-based materials. This enables localised manufacturing that bypasses traditional supply chains and the economic constraints imposed by conventional photovoltaic modules.

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 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.
