SC Solar offers turnkey equipment for single-junction perovskite and perovskite-silicon tandem production
Its systems support substrates ranging from 300 × 300 mm to 1.2 × 2.4 m, as well as G12 wafers
The company says it has delivered and obtained acceptance for 7 complete perovskite production lines
SC Solar, known for its solar module production equipment, is expanding its portfolio for single-junction perovskite and perovskite-silicon tandem manufacturing. Michael Li, Director of R&D at SC Solar, presented the company’s latest equipment developments at the TaiyangNews Conference on Cell & Module Production Equipment & Processing Materials 2026.
SC Solar’s 300 × 300 mm single-junction perovskite turnkey line covers glass cleaning, plasma treatment, coating, vacuum drying and crystallization, evaporation, atomic layer deposition (ALD), physical vapor deposition (PVD), laser scribing, testing, and lamination. The company can also provide the bill of materials (BOM), standard operating procedures, automation, and process support.
Material handling can be configured as semi-automatic transfer, fixed automation, or an automated guided vehicle (AGV) system. According to Li, AGV-based transfer gives pilot lines greater flexibility to change the equipment sequence, while fixed automation provides more stable material flow for mass production.
For large-area perovskite production, SC Solar has developed line concepts for 600 × 1,200 mm and 1.2 × 2.4 m substrates. The company says these lines are designed to process approximately one panel per minute. Conveyors and buffer stations balance different processing times and support continuous production.
The company develops key vacuum equipment, including PVD, ALD, evaporation, and vacuum drying and crystallization systems. According to Li, SC Solar’s internally developed vacuum systems account for more than 80% of the equipment value of a typical 100 MW production line. The company works with equipment partners for processes such as coating and laser scribing.
Its PVD portfolio includes vertical and horizontal magnetron sputtering systems for depositing layers such as nickel oxide (NiOₓ), indium tin oxide (ITO), and copper. SC Solar recommends a vertical configuration for large-area single-junction perovskite production and a horizontal design for wafer-based tandem cells. Li explained that tandem production requires different transfer and automation systems because it processes smaller silicon wafers instead of large glass substrates.
The company’s linear evaporation system supports LiF and C₆₀ deposition, as well as multi-source co-evaporation of inorganic perovskite precursors. It provides thickness non-uniformity of no more than 3% and maintains the substrate below 60°C, limiting the thermal exposure of the underlying perovskite films and interfaces.
For large-area modules, SC Solar offers a dual-layer vacuum drying and crystallization system supporting substrates up to 600 × 1,200 mm. It uses rapid evacuation, multi-stage pressure control, and airflow across the film surface to regulate drying and crystallization. Its inline version for perovskite-silicon tandem cells supports G12 wafers and has a reference throughput of around 500 wafers per hour.
At the module level, SC Solar provides an assembly line covering conductive-tape, busbar and insulation-film application, trimming, glass pairing, butyl sealing, lamination, junction-box processing, curing, and testing. Its lamination platform uses interchangeable tooling to process different module formats. The line supports single-junction perovskite modules as well as 2-terminal and 4-terminal tandem modules, with a reference output of one module every 40 seconds.
SC Solar says it has delivered and obtained acceptance for 7 complete perovskite production lines and has exported equipment to Europe and the US. In China, it has delivered a 1.2 × 2.4 m PVD system for NiOₓ deposition to BOE. The company has also supplied large-area PVD and evaporation equipment for GW-scale production.
