GCL Integration’s independently developed flexible crystalline-silicon–perovskite tandem solar cell was certified by the China Photovoltaic Product Quality Inspection and Testing Center (CPVT) at 33.44% power conversion efficiency. The ultra‑thin, bendable device withstands limited flexing without fracturing and delivers device‑level specific power above 2,000 W/kg, giving a clear generation‑per‑mass advantage versus conventional rigid cells and ranking it among industry leaders.

GCL Integration’s independently developed flexible crystalline-silicon–perovskite tandem solar cell was certified by the China Photovoltaic Product Quality Inspection and Testing Center (CPVT) at 33.44% power conversion efficiency. The ultra‑thin, bendable device withstands limited flexing without fracturing and delivers device‑level specific power above 2,000 W/kg, giving a clear generation‑per‑mass advantage versus conventional rigid cells and ranking it among industry leaders. The company says the materials and cell‑structure advances target high-efficiency PV applications in satellites, space stations and deep‑space exploration.
