Perovskite solar panels developers

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.

Flexell Space is South Korea's Hanwha Systems' in-house venture. 

It aims to develop solar cells for space, with high efficiency, low cost, extreme durability and more. It seems that it's products are CIGS/Perovskite tandem cells. Its key technology, according to the Company's website, is based on radiation resistance and self-curing capabilities to maintain performance until End-of-Life. 

In August 2024, Flexell Space signed a letter of intent (LOI) with Germany's Airbus Defense and Space to develop next-generation space solar cell modules.

In August 2025, KIER and Flexell Space signed a technology transfer agreement for aerospace solar cells.

Golden Solar New Energy Technology Holdings Limited (Originally Baofeng Modern International Holdings Company Limited) is an investment holdings company listed on the Main Board of the Stock Exchange of Hong Kong Limited (Stock Code: 1121). 

Earlier on, Golden Solar’s subsidiary, Quanzhou Baofeng Shoes Co., Ltd. engaged in the manufacture and sale of slippers, flip-flops, sandals and casual footwear for Original Equipment Manufacturer customers and design and manufacture of slippers under its own brands of Boree and Baofeng in China.

The Company set out to transform its business model. In addition to completing the acquisition of technological know-how in graphene materials technology, Golden Solar has been selectively hiring scientists and researchers. The company had since then successfully commercialized the graphene materials technology and its application in footwears and air purification devices, and thus re-positioned itself from a traditional manufacturing company to a materials science company.

Guosheng Shian Technology Co., Ltd. ( aka “Grand Sunergy Tech”, Shanghai Stock Exchange Code: 603778) specializes in ecological governance and has established a broad spectrum of professional services including project planning, architecture, landscape, tourism, municipal services, and ecological/environmental protection.

Grand Sunergy Tech primarily concentrates on the production of high-efficiency HJT cells and modules, as well as investment and operation in the upstream and downstream industrial chain. However, in August 2025, Grand Sunergy announced it is expanding into the perovskite tandem solar cell module sector and energy storage manufacturing. 

The company has signed an agreement with the local government of Tieling, Liaoning Province, to build a new energy industrial park with a total investment of RMB 3 billion ($416.67 million).

Founded in Eugene, Oregon and established in 2009, Grape Solar is a retail solar brand with over a decade of experience providing grid-tied, grid-interactive and off-grid solar systems to businesses and individuals. 

In September 2023, it was announced that Grape Solar appointed Dr. Leon Dong to Spearhead R&D Effort of Perovskite Solar Technology, as the Company is entering the field of perovskite solar R&D.

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.

Halocell Energy is focused on developing perovskite solar cell technology. Halocell Energy was renamed in 2023 from Greatcell Energy.

Halocell is dedicated to advancing the performance, stability, and scalability of perovskite solar cells to make them a viable and competitive alternative to traditional silicon-based photovoltaics.

Halocell uses halide elements in its perovskites along with many other aspects of cutting-edge materials science to harvest light across various settings and commercial applications. It develops products for indoor devices, outdoor devices and industrial assets.

Hangzhou Kelin Electric (KLEC) is a China-based power product manufacturer established in 2002.

In March 2025, KLEC announced plans to issue A-shares to raise up to RMB 1.46 billion ($201.65 million), part of which to be allocated to a 1 GW high-efficiency perovskite solar module plant and the remainder for working capital. The project, to be executed by its subsidiary Keneng New Energy, will be constructed in Hangzhou City, Zhejiang Province, with a 48-month construction period.

KLEC emphasizes its established partnerships with major utilities such as State Grid and China Southern Power Grid, ensuring demand for the facility’s future production capacity.
