Perovskite solar production

Mellow Energy has announced the launch of what it refers to as "the world’s largest integrated flexible perovskite photovoltaic (PV) module" from its 100MW-scale production line. The module measures 1.2×1.6 square meters and weighs approximately 2.04 kilograms.

According to Mellow Energy, tests conducted by TÜV Rheinland, an internationally renowned testing and certification body, have confirmed that the 1.2×1.6-square-meter double-glass module achieves a full-area efficiency of 17.9% under standard testing conditions.

Huasun Energy (Ningxia Huasun New Materials Technology) has marked the production of its first monocrystalline silicon rod at its 20 GW Heterojunction (HJT) Monocrystalline Silicon Smart Factory (Phase 1). The project is said to progress quickly, achieving milestones that include the successful completion of construction, equipment installation, and the commencement of production, setting a new benchmark for industrial development in Yinchuan, the capital city of Ningxia Province, Northwest China. 

Jin Wang, Senior Vice President of Huasun Energy, emphasized that the successful rollout of the first silicon rod underscores the successful completion of Huasun’s fully integrated HJT solar industry chain, spanning from silicon ingot and wafer to HJT cell and module. Huasun is committed to driving innovation in HJT technology and accelerating the industrialization of HJT-perovskite tandem technology to further reduce costs and enhance efficiency.

Kunshan GCL Optoelectronic Material, a perovskite optoelectronic technology company under GCL Technology Holdings, has recently completed the C1 round of financing led by Goldstone Investment, involving nearly RMB500 million (around USD$68,850,000).

This round of financing introduced institutions such as Kunshan High-Tech Group and HongShan to participate in the investment, and the proceeds will be used to build Kunshan GCL Optoelectronic Material's Kunshan gigawatt perovskite Ore stacked production line, which is expected to be put into operation in 2025. 

SEI Energy Technology (Jiaxing), a joint venture in China between Solaires Enterprises (Victoria BC, Canada) and Genesis Technologies (Shanghai), has announced the successful trial production of its perovskite modules from its mass production line. The companies view the success of this trial production as a significant breakthrough that demonstrates the potential of this production line, that lays a foundation for the large-scale commercialization of perovskite materials and solar modules. 

Solaires is focused on research and application development in the field of indoor light power generation. Its third party tested conversion efficiency reportedly exceeded 35% in 2024. In addition, SEI’s manufacturing process of perovskite materials is relatively simple, which can greatly shorten the production cycle and improve production yield. The raw materials used are environmentally friendly and have significant cost advantages. 

 Verde Technologies has opened a new research lab and pilot production facility in Waterbury Center, Vermont, which will aim to allow the company to build out its pilot lines and start producing larger thin-film solar cells for upcoming pilot projects with local and national partners. 

The research center is located in the former Suss Microtec facility. Verde's lead investor is VCET's Vermont Seed Capital Fund. Founded in Burlington by University of Vermont alums and researchers, Verde Technologies manufactures thin, lightweight and flexible perovskite solar panels. The Company says that "these American-made and manufactured panels are ten times lighter than traditional silicon solar panels and use a peel-and-stick installation method making them much more accessible and affordable". Verde’s technology will allow them to repower older solar fields to increase their output and utilize existing infrastructure.

Researchers from China's Dongguan University of Technology and Xi'an Jiaotong University have developed a spontaneous cooling strategy with a hot-pressing technique that enables the production of high-purity, wafer-scale, pinhole-free perovskite wafers with a reflective surface. 

This method can, according to the team, be extended to a variety of perovskite wafers, including organic-inorganic, 2D, and lead-free perovskites. The size of the wafer (with diameters of 10, 15, and 20 mm) can be tailored by changing the mold.

Global PV project developer and panel manufacturer, Renesola, recently held a groundbreaking ceremony for its 3GW PV module production factory in Longan District, Anyang City, Henan Province. The total investment for the project is approximately 3 billion yuan (almost USD$422 million).  

The first phase of the project will establish a 3GW photovoltaic module production line, along with essential production equipment such as frames, brackets, and welding strips, with the goal of creating a comprehensive photovoltaic industry chain. While this plant is not focused on perovskite-based PV, it is important to note that the second phase of ReneSola's Anyang base plans to establish a 2 GW Perovskite solar modules production line, covering an area of approximately 40,000 square meters. 

Hefei BOE Solar Technology has announced the successful production of the first 1.2m*2.4m perovskite solar module (in a line that was said to be completed in 38 days).

BOE said that its three major R&D platforms have all entered the first-class echelon of the industry, realized independent debugging of fully automatic intelligent production lines, and mastered the dry coating process. Currently, its glove box champion efficiency is 25.6%, and the experimental line champion efficiency is 20.63%.

Jiangsu Xiehang Energy Technology (Fellow Energy/Xiehang Energy), a holding company of Turkey’s Chen Solar photovoltaic module and smart device manufacturer, has announced its plan to build a perovskite solar cell and module factory in Sichuan Province, China.

Fellow Energy had negotiated with the local government of Dechang County, Sichuan Province, for the construction of the project. It plans to build a solar cell factory to produce 2GW of perovskite-silicon tandem solar cells and 5GW of high-efficiency solar modules annually upon completion of the facility.

Reports suggest that a number of renewable-related projects have recently been signed in Shanghai, China, including a 1GW perovskite module factory.

The perovskite solar module factory will be initiated by Wuxi UtmoLight Technology (UtmoLight), a China-based technology development company working towards perovskite commercialization, with a total investment of 1.5 billion yuan ( around USD$212,221,000), The new facility will be located in Heze City, Shandong Province.
