Perovskite solar panels developers

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.

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.

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.

China-based BOE is a large display maker. In March 2024, BOE established a new company called Hefei BOE Solar Energy Tech and started its research on solar cells with perovskite materials.

Hefei BOE Solar Energy is located in BOE's B9 factory and plans to have an R&D lab with total investment around CNY 91 M. This project gained green light from local government in May 2024 and is working to build a 300mm x 300mm R&D line which is able to produce 22500 sheets annually. 2 months later, in  July 2024, a 2nd construction was announced as an expansion plan with total cost around CNY 871 M. According to the official announcement, a pilot line will be built in the expansion plan with designed capacity around 912500 sheets of solar cell annually.

Although the Company is planning significant solar cell capacity, BOE claimed those solar cells are merely for R&D and exhibition use without any external sales.
