Perovskite solar production

LONGi Green Energy has reportedly filed a public environmental impact assessment announcement for a new "Novel Crystalline Silicon-Perovskite Tandem Solar Cell Technology and Equipment Industrialization Project," confirming plans to invest 204 million yuan (about $28 million) in a 100 MW pilot production line for high-efficiency silicon-perovskite tandem solar cells in Xixian New Area, Shaanxi Province.

According to the announcement, the project is classified as a modification and will occupy roughly 4,000 square meters within the existing plant of LONGi's previously registered Phase I Pilot Project at its Central Research Institute. Rather than building new facilities from scratch, LONGi will use the leased factory space and supporting infrastructure already in place, installing key equipment such as perovskite thin-film deposition systems, perovskite rapid crystallization tools and functional-layer thin-film deposition equipment to support R&D and pilot-scale testing of the tandem cells.

JA Solar is set to add 0.6 GW/year of perovskite tandem module capacity at its Yangzhou base, after the Management Committee of the Yangzhou Economic and Technological Development Zone published proposed approval opinions on the environmental impact assessment for the project on July 23, 2026.

The project, filed by JA Solar (Yangzhou) New Energy and titled the JA Solar Yangzhou Base Module Technology Upgrade Project, covers the company's existing facilities at No. 1 Jinhui Road and No. 123 Jinshan Road in the development zone, with a total investment of 210 million yuan (around $29 million). The perovskite tandem work is concentrated at the Jinhui Road plant.

Sunic System has reportedly completed Building A, the first phase of its new production complex in Pyeongtaek Brain City, with the full site expected to quadruple its manufacturing capacity compared with its current headquarters once Building B is completed. The completed facilities include the Building A production plant, office building and ancillary structures. The Pyeongtaek production complex is being developed on a 22,628-square-meter site with a planned total floor area of 15,756 square meters.

The new facility will serve as a key manufacturing base to meet growing demand for vacuum deposition equipment for Generation 8.6 OLED, OLED on Silicon (OLEDoS) and next-generation perovskite applications. Construction of Building B is targeted for completion in October, after which the company plans to begin operations at the Pyeongtaek site.

Hanwha Solutions’ Qcells division has reportedly completed the solar cell production line at its Cartersville factory in Georgia, paving the way for mass production to begin as early as this July.

This milestone finalizes the company’s U.S. “Solar Hub”, a vertically integrated manufacturing base that covers the full value chain from ingots and wafers through cells to finished modules, all produced domestically. Once ramped, the hub is expected to support several gigawatts of annual ingot, wafer and cell output, alongside 8.6 GW of module capacity.

Perovskite solar cells have made rapid gains in efficiency, with both single-junction and tandem configurations continuing to set new performance records. As the industry moves toward commercial-scale production, thermal evaporation has emerged as a leading deposition method for many of the layers in the perovskite device stack. This includes the perovskite absorber itself (via co-evaporation of precursors such as PbI₂, CsBr, and MAI), metal contacts, hole and electron transport layers, and buffer layers.

For manufacturers accustomed to chemical vapor deposition and solution-based processes, thermal evaporation introduces a different set of process control requirements. Deposition rates in perovskite manufacturing are often very low, materials can be exotic with poorly characterized physical properties, and multi-source co-evaporation demands simultaneous rate control of each material. The technology that addresses these requirements is quartz crystal microbalance (QCM) monitoring. QCM has decades of proven use in optical coating and OLED manufacturing but is relatively new to the solar industry. Understanding how it works and what it enables is becoming essential as perovskite fabs scale up.

This is especially relevant given one of the central challenges facing perovskite solar today. Long-term cell stability remains an active area of development for the industry. Perovskite devices are sensitive to the thickness and composition of each layer in the device stack. Variations in absorber thickness, transport layer uniformity, or buffer layer coverage can accelerate degradation mechanisms that shorten cell lifetime in the field. Accurate deposition control is not just a manufacturing efficiency concern. It directly affects how long the finished solar cell will perform at its rated output.

TandemPV has announced the opening of its commercial demonstration factory in Fremont, California. The facility marks a step toward commercializing U.S.-manufactured next-generation solar panels for utility-scale projects.

As electricity demand rises, driven in part by data centers and AI workloads, utilities are moving quickly to add new capacity. Tandem PV’s Fremont factory supports efforts to reshore advanced solar manufacturing and reduce reliance on overseas supply chains. The line is designed to demonstrate that perovskite-silicon tandem panels can be manufactured reliably in the United States at scale with high power density, durability, and lower costs.

According to recent reports, Italian company New Time has announced a four-phase plan to advance perovskite solar cell production in Italy. The roadmap was presented following a strategic meeting held in Forlì, in the Emilia-Romagna region. In late 2025, it was reported that Italian architectural solutions company New Time is working with China's Huasun to bring perovskite panel production to Italy.

During the first year, New Time plans to focus on refining the perovskite formula and identifying stabilizing materials to improve performance and durability. The second phase will introduce limited-scale production aimed at obtaining product certification. In the third year, the company intends to establish a full industrial manufacturing solution, followed by large-scale production in the fourth year. Pilot-scale output is expected within three years.

According to reports, China Construction Second Engineering Bureau is working on a major renewable energy project in Baisha Industrial Park, Jiangjin. The company is building a 3GW perovskite solar cell module base.

As a large perovskite solar cell module production base in Southwest China and a core element of the Jiangjin photovoltaic industry chain, the project has recently completed the key phase of installing the metal roof on the steel structure factory building. Decoration and finishing works are now in full progress, with completion and delivery expected by the end of October 2026.

PV equipment manufacturer Shenzhen S.C New Energy has shipped its first mass-production turnkey line for flexible perovskite solar modules, expanding from standalone equipment supply to full-line delivery in this segment.

The production line covers core manufacturing processes for flexible perovskite modules, including high-precision cleaning systems; laser scribing equipment for cell isolation and interconnection; multifunctional coating and deposition tools supporting both solution-based and dry processes; and downstream lamination and IV solar simulation testing systems.

Perovskite solar technology represents a quantum leap in photovoltaics with efficiencies that exceed conventional limits. For the production of efficient thin-film modules, precise structuring of large-area layer systems into serially interconnected cell segments is essential.
