From September 23 to 27, 2025, the 18th National Conference on Solar Photochemistry and Photocatalysis was successfully held in Tianjin. Co‑organized by Tianjin University and the Chinese Society for Renewable Energy, the conference was jointly chaired by Academician Ye Jinhua of the European Academy of Sciences and Professor Gong Jinlong. Under the theme “Harnessing the energy of the dual‑carbon goals to bestow a new light of quality,” the meeting brought together more than 1,400 delegates from over 330 universities, research institutes, and companies at home and abroad to carry out in‑depth and wide‑ranging academic exchanges on frontier issues in solar photochemistry and photocatalysis. As a premier sponsor of the conference, Beijing Perfectlight Technology Co., Ltd. was honored to participate and witness the important outcomes and collaborative opportunities presented at this event.

During the conference, Perfectlight hosted an exhibition booth and conducted multiple equipment demonstrations and technical exchanges. Dr. Cai, Spectral Optical Technology Manager of the company, delivered a presentation titled "Instrument Development for Research on New Methods of Photocatalytic Conversion: Multi‑field Coupling + Process Optimization + Application Validation", outlining Perfectlight’s practical approaches in instrument development, engineering scale‑up, and application validation. The talk focused on frontier research in photocatalytic conversion—centering on multi‑field coupling mechanism exploration, process optimization (e.g., continuous flow, high‑throughput screening), and real‑world application challenges—which urgently require professionally matched instruments. Addressing shortcomings in traditional devices regarding integration, controllability, and application matching, Dr. Cai introduced the company’s recent progress in a series of novel reaction and testing systems, typically including: a multi‑channel cascade reactor system for studying photo‑thermal catalytic elementary processes and multistage reactions; a dual‑axis tracked flat‑plate reactor system for outdoor solar photothermal (and photoelectro) validation; a continuous‑flow photoelectrochemical testing system for precise characterization and process scale‑up of photoelectrocatalysis; and several systems for exploring new reaction paradigms such as photo‑plasmonic synergy and gas–liquid–solid multiphase processes. These systems closely address the specific application needs of research into new photocatalytic methods, aiming to provide precise and efficient research tools for revealing reaction mechanisms, optimizing processes, and promoting the translation of laboratory results, attracting high interest and discussion from attending experts and peers.
Perfectlight exhibited several representative products with live demonstrations and exchanges. The main exhibits included:
μGAS1001 Trace Gas Reaction Evaluation System;
PLR STPRS‑O3 Portable Solar Tracking Photoreactor;
PLR PECTS‑L2200 Continuous‑Flow Photoelectrocatalysis Testing System;
Rapid‑heating Multi‑field Fixed‑bed Reactor;
Solar Photothermal Catalysis Simulation Apparatus.
Perfectlight’s booth was crowded, with visitors stopping to watch the equipment demonstrations. Researchers, company representatives, faculty, and graduate students continuously queued to experience and inquire. Engineers and technicians performed live operations and explained data at the demonstration table, providing detailed technical answers and experimental demonstrations on issues such as gas detection with the μGAS1001, the solar tracking performance of the PLR STPRS‑O3, and the photoelectro coupling tests of the PECTS‑L2200. Interaction was lively, and the Perfectlight booth became an important academic‑industry matchmaking hotspot at the conference.
Perfectlight has always taken green, low‑carbon development and technological self‑reliance as one of its corporate missions. This conference deepened the company’s understanding of technical pathways related to new energy and carbon reduction, and provided new ideas for Perfectlight’s subsequent promotion, demonstration, and industrialization of photochemical and photocatalytic technologies. The company will continue to drive progress through technological innovation, support the application of photochemistry‑related technologies in energy transition and environmental governance, and contribute to the national "dual‑carbon" goals.
Finally, we thank the conference organizers for providing a high‑level academic exchange platform, and express gratitude to the experts, scholars, and partners for their attention and support to the Perfectlight booth and presentation. Going forward, Beijing Perfectlight Technology Co., Ltd. will continue to deepen its R&D and engineering capabilities, promote more equipment and technical services to frontline research and industry, actively participate in collaborative innovation between academia and industry, and jointly advance the sustained development and industrialization of solar photochemistry and photocatalysis.
Institutions, research institutes, and companies interested in cooperation are welcome to contact Perfectlight to discuss technical collaboration and product application support (Consultation hotline: 400-1161-365), together seizing the major opportunities presented by photochemistry and photocatalysis in the green, low‑carbon transition.
