Founded in 1999, First Solar is an American solar technology company and global provider of responsibly produced, eco-efficient solar modules advancing the fight against climate change.

 The company is a U.S-headquartered company and does not manufacture in China. First Solar’s advanced thin film photovoltaic (PV) modules represent the next generation of solar technologies, providing a competitive, high-performance, lower-carbon alternative to conventional crystalline silicon (c-Si) PV panels.

In May 2023, First Solar acquired Evolar.

Beijing Yaoneng Technology Co., Ltd. was registered in Beijing (Haidian) Overseas Students Pioneer Park in 2017, and has obtained the Zhongguancun high-tech enterprise qualification. Its main business is in the field of new energy materials, and the research and development products are devices, processes and materials for perovskite/crystalline silicon tandem solar cells and modules. 

It is the earliest domestic enterprise dedicated to the industrialization of perovskite crystalline silicon tandem solar cells.

Evolisun Energy, co-based in China and Germany, focuses on the evolution of lithium and solar Energy. Evolisun has been working on perovskite solar cells since 2010.

Evolisun is also dedicated to worldwide supply of battery energy storage systems embedded with vertical integrated and purpose-built solutions into the demands of residential, commercial and industrial and microgrid application.
 

WattByWatt is a Canadian company that grew from university research on perovskite technology.

WattByWatt offers complete solutions for the production, storage and management of renewable energies. The company develops electronics devices, energy production installations and more.

WattByWatt chemically synthesizes perovskite in their Quebec facility reproducing the inherent semiconductor property and ensuring a consistent product. WattByWatt’s patented manufacturing process means the PEROVTON photovoltaic modules can be manufactured without the expense of a clean room. WattByWatt’s perovskite inks can be thin film printed to manufacture sustainable, high efficiency photovoltaic cells and modules. 

Their SmartFlower solar panel follows the sun from sunrise to sunset producing and storing renewable energy in its integrated battery storage system. The company sees the use of SmartFlowers in agrivoltaic farming as a global energy game changer.

Verde Technologies is an NSF, DOE/SETO-funded startup, and NREL collaborator that spun out of the University of Vermont. Its core competency is the rapid transition from lab-scale to full-scale manufacturing of stable, efficient, and safe perovskite solar cells using existing manufacturing infrastructure.

Verde Technologies was founded by Doctors Randall Headrick and Richards Miller in 2021. With Randall’s expertise in thin films and Richards’ experience in the lab, the two invented a novel solar cell that will accelerate the renewable energy transition. 

Enel Green Power was founded in December 2008 inside the Enel Group to develop and manage power generated from renewable resources worldwide.

The Company manages more than 1,200 power plants on five continents and has assets in operation or under construction in many countries and manages development activities in a further 5 countries. It has over 56 GW of installed renewable capacity from a mix of renewable resources, including wind, solar, hydroelectric and geothermal. It's also one of the founding members of RES4MED – Renewable Energy Solutions for the Mediterranean and Beyond – an association created in 2012 to promote renewable energy and the infrastructure needed to deliver electricity throughout the Mediterranean area.

Enel Green Power is also involved with perovskite solar cell development, with plans to offer more efficient solar modules based on tandem silicon-perovskite cells. The final products are planned to reach efficiencies of around 30%.

Ascent Solar (NASDAQ: ASTI) manufactures flexible thin-film solar solutions that bring electric power to use cases where mass, shape & survivability matter.

Ascent solar films are developed using proprietary CIGS manufacturing processes. Its thin film PV panels are manufactured using CIGS (Copper-Indium-Gallium-Selenide) with patented monolithic integration. The patent-protected processes enable the company to precisely apply layers of these elements on a thin (25micron) polyamide substrate to create resilient and featherweight panels that convert sunlight into electric power.

Ascent Solar is also involved with perovskite solar developement. 

Taiwan Perovskite Technology (TPT) is focused on the field of perovskite solar cells (PSCs), providing integrated solutions and innovative services.

As PSC experts, TPT provides measuring instruments and integrated solutions covering design, research and development, software, sample testing, analysis and management, so that customers can effectively and accurately measure the highest conversion efficiency of PSCs.

QD Solar Inc. is a start-up out of Toronto, Canada, commercializing IP-protected world-leading cutting-edge photovoltaic research out of the University of Toronto.

The team combines perovskites with other solar materials in a tandem configuration to take solar beyond efficiencies achievable using standard silicon technology.

As part of Canada’s effort towards a zero-carbon, zero-waste economy, QD Solar was awarded CAD$5.3 Million in non-dilutive funding by SDTC, Canada’s largest federal cleantech fund

U.S-based Halldata Solar is a printing company that prints a wide range of specialized labels and tags for a variety of specialized applications. It aims to use its 30 years of printing knowledge to manufacture flexible perovskite solar films.

The company has many printing technologies in its 22,000sf facility in eastern Washington State that give it the experience to create perovskite solar cells:

•  Roll-to-Roll Printing
•  Flatbed Screenprinting
•  Flexography
•  Plate Making
•  Convection and UV Curing
•  Conductive Inks
•  Slot Die & Rod Coating

​Halldata wishes to turn university research into working solar cells, and is working to establish a thin film perovskite solar cell manufacturing facility near Hanford, USA.
