Perovs, commercially registered as Hangzhou Zhongneng Optoelectronic Technology Co., Ltd., is a high-tech Chinese enterprise specializing in the industrialization of third-generation photovoltaic technologies. Founded in 2015 and headquartered in Hangzhou, Zhejiang Province, the company has established itself as a pioneer in the field of Perovskite Solar Cells (PSCs) and Organic Photovoltaics (OPV).
Unlike many solar entities that focus solely on panel manufacturing, Perovs operates on a "Two-Wheel Drive" strategy: it simultaneously develops high-efficiency perovskite solar modules and the specialized manufacturing equipment required to produce them. This dual approach allows the company to iterate its production processes rapidly, serving both as a materials innovator and a critical equipment supplier to the broader thin-film solar industry.
The company was founded by a technical team with roots in Tsinghua University and Huazhong University of Science and Technology. It has been recognized as a National High-Tech Enterprise and maintains a significant R&D footprint, focusing on solving the scalability and stability challenges inherent in converting perovskite technology from laboratory scale to mass production.
Core Products and Technology
Perovs? business model allows it to offer comprehensive solutions ranging from individual lab instruments to complete pilot production lines.
1. Advanced Manufacturing Equipment
Perovs is a leading domestic supplier of "turnkey" solutions for perovskite production. They design and manufacture the complex machinery required to deposit nanometer-thin layers of materials on glass or flexible substrates.
Slot-Die Coating Systems: The company?s flagship product line. Slot-die coating is the industry-preferred method for depositing perovskite inks over large areas with high uniformity. Perovs offers systems ranging from small-scale lab coaters to large-area automated production tools compatible with Roll-to-Roll (R2R) or Sheet-to-Sheet (S2S) processes.
Laser Scribing & Etching Machines: Precision laser tools used for the monolithic interconnection of solar cells. These machines perform the P1, P2, and P3 scribing steps necessary to connect individual cells in series within a module, a critical step for maximizing voltage and efficiency.
Vacuum Deposition Equipment (PVD): For layers that cannot be solution-processed (such as metal back electrodes or specific transport layers), Perovs manufactures thermal evaporation and magnetron sputtering systems tailored for delicate organic/perovskite materials.
Crystallization & Drying Systems: Specialized VPD (Vacuum Flash Drying) and gas-quenching tools designed to control the crystallization kinetics of perovskite films, ensuring dense and defect-free light-absorbing layers.
2. Perovskite Solar Modules (PSMs)
While a major portion of their business is equipment, Perovs actively develops and certifies its own solar modules to validate its machinery and proprietary processes.
Rigid Modules: The company produces large-area perovskite modules on glass substrates. They have achieved notable third-party efficiency certifications (e.g., reaching steady-state efficiencies >18% on commercial-size sub-modules).
Flexible Modules: Leveraging their Roll-to-Roll equipment capabilities, Perovs develops lightweight, flexible solar films suitable for BIPV (Building Integrated Photovoltaics) and portable electronics.
Technology Roadmap: The company is actively transitioning from MW-scale pilot lines to GW-scale mass production, with planned production bases (such as in Xining, Qinghai) aimed at large-scale commercial deployment.
Research and Development Services
Perovs acts as an incubator and partner for academic and industrial researchers.
* Turnkey Lab Solutions: They provide universities and research institutes with complete "Perovskite Labs," delivering installed and calibrated production lines that allow scientists to focus on material chemistry rather than equipment engineering.
* Process Consulting: Leveraging their internal pilot lines (100-500kW capacity), the company offers process optimization services, helping clients scale their recipes from spin-coating (lab scale) to slot-die coating (industrial scale).
Strategic Significance
Perovs plays a critical role in the "six bases" of China?s advanced basic process field. By domesticating the supply chain for perovskite manufacturing equipment, the company reduces the industry's reliance on imported tools and lowers the capital expenditure (CAPEX) required to build new solar factories. Their work accelerates the timeline for perovskite solar cells to compete directly with traditional silicon panels in the energy market.
