GCL Tech, along with its perovskite cell technology-based product development subsidiary Kunshan Photoelectric Materials Co. Ltd, promoted its latest perovskite product offerings at Intersolar Europe 2024. According to the company statement, Kunshan Photoelectric Materials Co. Ltd is building the world’s first GW-level production base for large-size (1.2 x 2.4 m) perovskite tandem modules.
Perovskite module
Speaking to TaiyangNews at the event, the company showcased its latest PV modules based on perovskite cell technology. The company displayed 2 different versions of perovskite cell-based modules – the Single-Structure Perovskite Solar Module & the Tandem Perovskite Solar Module. GCL’s Single-Structure Perovskite Solar Module, measuring 1,000 x 2,000 mm, boasts an efficiency of up to 19.04%. The company noted that the low synthesis temperature of below 200℃ required for perovskite layer fabrication could cut carbon emissions by more than 90%.
Besides the single-junction perovskite module, the maker promoted its latest perovskite PV module based on the perovskite layer topped on a silicon solar cell or perovskite tandem cell technology. The Tandem Perovskite Solar Module’s conversion efficiency reaches up to 26.36% in module dimensions of 1.71 m². The company claims its perovskite-silicon product has cleared all efficiency stability tests conducted by TÜV Rheinland. The company expects to commercialize a tandem perovskite module with a conversion rate of 27% or above after the inauguration of a 500 MW perovskite stacked module plant in mid-2025.
n-TOPCon module
The company also launched an n-TOPCon cell-based standard dual-glass PV module under the GCL-NT12R/66GDF series. The module, featuring a half-cell matrix consisting 132 pieces of 210 mm cells, boasts a power output of up to 620 W and an efficiency of 23%. This model offers 5 different power classes between 595 W and 620 W. The 2,382 x 1,134 x 30 mm dimension module, laminated with 2 mm thick front and rear glass, is suitable for utility-scale projects and certified for sand abrasion tests, salt mist tests, and ammonia tests. GCL Tech further added that the latest module is certified for up to 2,400 Pa front-side wind load and 5,400 Pa rear-side snow load capacity.
For the GCL-NT12R/66GDF series, the mainstream power classes of 610 W to 615 W are now in mass production. With an ongoing upgrade in technology and production, the 620 W version is expected to be in mass production within the next few months, added the company. GCL-SI offers a 12-year product warranty and a 30-year linear power warranty for this product.
