GCL Optoelectronic Material
Listed on the Hong Kong Exchange in 2014, GCL Optoelectronic Material (GCL New Energy) is an energy company under the GCL Group. Its primary business is solar power generation, covering development, construction and operations. GCL New Energy focuses on both centralized and distributed PV power plants to provide the society with sustainable green energy that is clean, safe and efficient.
With 14 domestic regional subsidiaries, GCL New Energy operates across China, moreover, it has three regional subsidiaries in North America, Japan, and Africa, and established overseas representative offices in or dispatched developers to key overseas target markets.
While GCL's PV work is not solely focused on perovskites, it does have several directions of development having to do with perovskite materials and technologies. GCL representatives stated that the company’s lab has achieved a conversion efficiency of 16% on a large panel and are confident 18% could be achieved as well.
GCL has an experimental 10 MW perovskite production line in operation, which it intends to ramp up to 100 MW soon and following that with a 1GW fab.

GCL Perovskite completes first end-to-end production run on its GW-scale module line
GCL Perovskite has completed an end-to-end production run on its GW-scale perovskite module manufacturing line, covering the full process from raw-material intake through to large-area module production. The company said commercial module deliveries are gradually increasing as it shifts focus to production stabilization and yield ramp-up, with current priorities centered on equipment stability during continuous operation, overall line yield, material utilization, and reducing unit manufacturing costs.

GCL Perovskite also said its 2 m² single-junction perovskite module has received third-party certification to IEC 61215, while its perovskite-crystalline silicon tandem module has received both IEC 61215 and IEC 61730 certification. The company led drafting of a space perovskite PV module standard last month.
GCL introduces perovskite-BC tandem module and mobile solar system to Latin American market
GCL showcased a perovskite-back contact (BC) tandem photovoltaic module alongside its EcoPower Mate mobile solar system at the Intersolar South America 2026 event, marking the company's entry into Brazil with technologies aimed at diversifying Latin America's solar offering across grid-connected and off-grid applications.
The perovskite-BC tandem module combines GCL's perovskite technology with back-contact cell architecture, in which electrical contacts are positioned on the rear of the cell rather than the front. In a tandem structure, the two materials capture different portions of the solar spectrum to boost overall conversion efficiency. GCL described the product as part of its long-term technology roadmap, following certified efficiency milestones the company has reported for its perovskite-silicon tandem modules, including a 29.51% result for a 2,048 cm² module. No efficiency figures were disclosed for the perovskite-BC tandem product shown in Brazil.
GCL Perovskite partners with Wuhan Lingyun on BIPV curtain walls and PV windows
GCL Perovskite has signed a strategic cooperation agreement with Wuhan Lingyun Building Decoration Engineering, covering perovskite building-integrated photovoltaic (BIPV) curtain walls and PV windows. The partnership spans joint R&D, product supply, EPC contracting, and market development.
Under the agreement, GCL Perovskite will contribute its gigawatt-scale production capabilities and BIPV product portfolio, while Wuhan Lingyun will bring its design, manufacturing, and construction expertise in architectural curtain walls. The two companies plan to jointly develop perovskite PV curtain wall and window products targeted at green-building applications, including low-carbon public buildings and ultra-low-energy buildings.
GCL Perovskite leads drafting of space perovskite PV module standard
GCL Optoelectronic Material (also referred to as GCL Perovskite) is leading the drafting of a group standard for single-junction perovskite solar modules intended for space applications. The Perovskite Industry Branch of the China International Association for Promotion of Science and Technology (CIAPST) organized the first drafting meeting, hosted by GCL.
The standard is meant to establish technical requirements and test methods for single-junction perovskite modules used in space, supporting their transition from technology validation to standardized, industrial-scale application. The move comes as the company continues building out its perovskite manufacturing and certification track record, including its 18.04% efficiency milestone for single-junction perovskite modules and certification for 3x IEC accelerated aging tests.
GCL Optoelectronics raises over US$14 million in D1 financing round, certifies 30.23% efficiency for large-area perovskite tandem module
GCL Optoelectronic Material (Kunshan GCL Optoelectronic Materials), a subsidiary of GCL Group, has completed a D1 financing round exceeding 100 million yuan (over US$14 million), led by Jinxin Capital, with Sequoia China, Xiang'an Venture Capital and Suzhou Asset Management participating. The company says the funds will primarily support the commercial delivery of its ground-mounted photovoltaic power stations and the verification of space photovoltaic applications.
The D1 round follows a Series C2 round completed in July 2025 that raised nearly 200 million yuan. Since its first angel round in May 2020, GCL Optoelectronics has attracted strategic investments exceeding one billion yuan from companies and institutions including CATL, TCL Group, Tencent, Temasek and Sequoia Capital.
