Oxford Photovoltaics Limited (Oxford PV) was founded in 2010 as a spin-out from the University of Oxford to commercialize a new technology for thin-film solar cells. It was amongst the first in the world to recognize the potential of perovskites to act as a low-cost, highly efficient solar cell absorber material to convert sunlight into electricity.

Oxford PV is developing and commercializing thin-film perovskite solar cells, which can be printed directly onto silicon solar cells, CIGS solar cells or glass. Pioneering work developing perovskite thin-film solar cells has delivered a route to boosting the efficiency of current commercial cells; using a high efficiency coating in a multi-junction or “tandem” cell architecture. In addition, printing perovskites directly onto glass has led to a semi-transparent coating ideal for BIPV applications and, once integrated into the glazing units of a building, the technology is capable of providing a significant percentage of the building’s electrical energy requirements directly from sunlight.

By employing well known and well understood printing processes, focused on inexpensive and abundant raw materials, Oxford PV has developed a highly cost effective technology.

Panasonic Corporation is a Japan-based worldwide leader in the development of diverse electronics technologies and solutions in the consumer electronics, housing, automotive, enterprise solutions and more.

Panasonic is focusing on the development of perovskite solar cells and takes part in various research activities like the Solliance program (as part of a research program concerning the development of roll-to-roll manufacturing processes aimed at large scale production of flexible perovskite solar cells where it will be one of the industrial partners), research work with EPFL, and more.

In March 2018, Panasonic and Sekisui Chemical announced the development of perovskite-based solar cells that can be attached to walls and curved surfaces.

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.

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.

Solaires Enterprises (SE) is a Canada-based company aiming to make solar energy more accessible. It is committed to reducing the amount of greenhouse gas emissions with an ethical manufacturing process.

Its solution uses technology that incorporates perovskites into its Solar Ink that has a unique formulation that allows the fabrication of perovskite film with high energy conversion efficiency and high stability.

This allows SE to develop products, such as photovoltaic blinds, tiles, and windows, that incorporate the technology and reduce the average consumer's carbon footprint.

SE's inks can be used for different types of rigid and flexible substrates. It has been specially formulated to make it compatible with different fabrication processes, including spin coating, slot-die and blade-coating.

Due to the high photoluminescence quantum yield of perovskites at room temperature, SE's Solar Ink can also be used for light-emitting diodes (LED) applications with strong emission in the near-infrared region.

In 2023, the company started producing and marketing perovskite solar panel modules.
