United Renewable Energy (URE) is a privately-held engineering, procurement, and construction (EPC) firm developing photovoltaic farms and energy storage systems for utilities, industrial and commercial companies, Independent Power Producers, and Electrical Membership Cooperatives.

Founded in 2008 and headquartered in the U.S, URE is a fast-growing solar energy contractor with an impressive client list. In 2021, announced that it has made a breakthrough in developing perovskite solar cells in collaboration with National Taiwan University, with energy conversion rates reaching as high as 26%. URE said it also developed N-type HJT and TOPCon solar cells. URE has reportedly begun shipments for HJT solar cells with a maximum energy conversion rate of 24.5% and will start small-volume production of TOPCon solar cells in 2021.

A team of scientists (Anand Verma (co-founder, CEO), Dr. David Martineau (CTO), Dr. Toby Meyer (co-founder, CEO Solaronix), and Andreas Meyer (CTO Lumartix)) have developed a digital printing technology to fabricate efficient and stable perovskite solar cells with custom design capability.

The fabrication techniques they developed are said to be highly efficient and flexible, which could reduce the production cost considerably, even for customized items.

With this breakthrough, the team hoped to cater to the diverse needs of Internet of Things, electronic goods, sensors, and ultimately designer solar tiles industries. They are already working with a couple of industrial clients where customized solar cells have been successfully tested.

These collaborations are planned to generate first revenues for the startup, and will establish the company among the first to commercialize perovskite solar cell technology in real-world electronic devices (lab to product).

In January 2021, Perovskia won funds from Venture Kick, which will be used to acquire research projects with prototyping for clients, promotions and IP. This will also help in getting new funds from agencies like the EU, and further develop the technology for the current customers.

Evolar has been spun out of Uppsala University's thin film solar cell research cluster. Evolar aims to produce perovskite solar cells at a high volume.

Evolar defines itself as an expert on evaporation of thin film materials with solid industry experience and world leading technology achievements. It plans to use its know-how to design reliable solar cells and to fast scale new manufacturing processes.

It has a high throughput R&D line running 24/7 with a large number of experiments under production like conditions. Using its unique method to mechanically stack perovskite and conventional solar cells, Evolar achieved high efficiency as well as ease of integration.

In November 2020, Evolar announced that it is partnering with Magnora ASA, a leading investment company in renewable energy. The raised capital will be spent to scale the processes in Evolar's high throughput R&D tools and prototype line in Uppsala, Sweden and thereby bringing its technology to the market in the near future.

Energy Materials Corp. (EMC) is focused on the development of high-speed, roll-to-roll printing of purebred perovskite solar panels.

EMC's manufacturer business model is based on leveraging joint development partners: Kodak's manufacturing facilities, and Corning's materials innovation, and combining them into a unique manufacturing model. This model inverts the restrictive, go slow paradigm with a pursuit of speed: in manufacturing scale-up, production throughput, capacity expansion and early revenue.

With over 100 years of Kodak printing experience and data informing development, EMC's model is mapped for rapid, broad market segment participation, market disrupting product pricing, and gross margins that are more than twice that of current module manufacturers.

Tandem PV is a U.S-based company working on mechanically-stacked perovskite+silicon tandem solar panels. The Company started its way as Iris PV, which was later changed to Tandem PV.

Colin Bailie, the Company's CEO and a Stanford alum, joined forces with solar industry veteran Chris Eberspacher (former CTO at Hanwa and Applied Materials SunFab) and together, they have raised a few millions in grant funds and other support to get closer to their goal.

Tandem PV strived to achieve high-Efficiency PV for high-value applications. Tandem PV’s approach to manufacturing photovoltaic cells is to deposit a metal-halide perovskite solar cell, which is transparent to infrared light, over a silicon-based cell, which then absorbs that infrared energy.

UK-based Power Roll was established to develop and commercialize its innovative proprietary energy storage and energy generation technologies. PRL's mission is to produce ultra-thin flexible solar photo-voltaic films in continuous rolls using rapid low-cost process.

In 2011 Dr. John Topping, the Company's Chief Scientific Officer, developed the initial concept behind the Power Roll's proprietary grooved based technologies and undertook initial proof of concept studies. In December 2012, John together with Saul Joicey co-founded and established Big Solar Limited (now Power Roll Limited) with some early stage seed capital.

Since then, PRL continued to evolve and now is solely focused on perovskites - although its architecture allows for multiple absorber materials to be used.

PRL reports that it has validated its technology using perovskites with the aid of The University of Sheffield and is currently working with NREL and SPECIFIC to promote scale-up.

PRL has also worked with Solliance in the past who did a technology validation with its architecture.

In 2021, Hunt Perovskite Technologies merged with 1366 Technologies to create CubicPV.

Founded in 2013, Hunt Perovskite Technologies (HPT) specializes in highly-stable and efficient metal halide perovskite in single-junction solar panels for the utility-scale market.

HPT claims that after achieving highly-efficient (>18%) metal halide perovskite PV devices in spring 2014, it resolved to stabilize the perovskite material through better chemistry. Its early tests showed that even though the perovskite devices were highly-efficient and very reproducible, all the materials that made for an efficient device, also caused the PV device to fail.

HPT's team of scientists and engineers has designed its own stable and efficient perovskite solar cell from the ground-up. HPT is also exploring other applications incorporating its highly-stable and efficient perovskite semiconductor.

Greatcell Energy was formed following Greatecell Solar's liquidation. Greatecell Energy acquired all of Greatcell Solar's IP, equipment - and Italian subsidiary.

The company's main focus is on the low-light, indoor IoT market. Using a roll-to-roll low-cost method, the company developed a high-efficiency perovskite indoor solar panel and is now upscaling its facilities for production.

Greatcell energy also has a long term full-sun research program with several universities and large innovative corporations.

Swift Solar is a U.S. startup designing and manufacturing perovskite solar panels that are cheaper and more efficient than conventional panels.

The Swift Solar team includes leading solar technologists from Stanford, MIT, Cambridge (UK), Oxford (UK), and the University of Washington, with deep expertise in perovskite photovoltaic technology and scale-up. Swift's core technologies range from new solar cell architectures to specialized manufacturing techniques initially developed in the labs at Stanford and MIT.

Toshiba is a Japan-headquartered multinational conglomerate that manufactures and sells various products and services including information technology and communications equipment and systems, electronic components and materials, power systems, industrial and social infrastructure systems, consumer electronics, household appliances, medical equipment, office equipment, lighting and logistics and more.

In September 2017, Toshiba announced the fabrication of a film-based perovskite solar cell mini module with an impressive conversion efficiency of 10.5%. This efficiency rate was achieved in a 5 cm x 5 cm module and is stated by the company to be the highest yet recorded in a multi-cell mini module.
