France-based Holosolis is a solar developer that was founded by three European entities: EIT Innoenergy, a clean-tech investor based in the Netherlands and financed by the EU; IDEC Group, a real estate developer in France; and TSE, a prominent solar energy producer in France and a leader in agrivoltaics. 

Holosolis is committed to manufacturing energy efficient modules using the latest photovoltaic technologies, with the lowest carbon footprint and highest social standards. It plans to build a state-of-the-art module gigafactory in Sarreguemines, Moselle, France, that will start production in 2025. It aims to produce 10 million PV panels per year.

Holosolis will accelerate innovation across the entire photovoltaic value chain, from raw materials to recycling, with products designed for the following markets:

* Residential rooftops
* Industrial and commercial rooftops
* Agrivoltaics
* Utility scale

In 2023, German silver metallization paste maker Heraeus acquired an unspecified stake in HoloSolis. Also, Germany’s Fraunhofer Institute for Solar Energy (ISE) said that it will support HoloSolis in setting up its planned manufacturing facility.

Founded in 2000, LONGi Green Energy Technology Co., Ltd. (LONGi) is a solar technology that develops solutions for large-scale power plants and for different industries and households with its innovation-focused development. Eventually, it also plans to supply "Green Power + Green Hydrogen" solutions for global zero-carbon development.

Since 2015, LONGi has located its operations in Yunnan, China, and Kuching, Malaysia, to utilize the abundant local hydropower resources to provide clean energy for its facilities. LONGi plans to integrate solar power plants with pumped storage in areas that feature significant elevation differences and abundant sunlight, creating an industrial model for using solar. 

On its website, LONGi states that "the LONGi R&D team has achieved successive breakthroughs in key technologies. These include perovskite thin-film crystal growth on textured silicon substrates, high-efficiency bulk passivation and optical management, and these advancements have led to rapid improvements in the efficiency of silicon-based stacked cells".

Mellow Energy, a China-based perovskite solar module manufacturer, was founded in August 2022. It is also sometimes called Vein Energy. The Company was incubated by the New Energy Technology Research Institute of Jinan University and is led by Professor Mai Yaohua, the dean of the institute.

In November 2022, the Company completed an angel round of financing and began constructing a pilot production line in Foshan High-tech Zone. The production line is used to research and develop key technologies to commercialize large-area perovskite solar cells and modules, as well as to manufacture indoor light energy collection and flexible mobile energy products. By February 2023, the perovskite 100 MW module (30cm x 30cm) pilot line was operational. By December 2023, it is said to be producing PCE = 22.9% modules. This is claimed to be certified by a Chinese 3rd party lab.
