Perovskite: an option that can zero existing assets early
Efficiency already wins; lifetime does not—valuations accrue tech-zero risk
- Jun 2025GCL Kunshan GW tandem line starts (claimed first)
- Dec 20252 m² tandem steady 27.06%; IEC safety cert
- Mar 2026Small-batch production, 98%+ yield, early deliveries
- Jun 2026Large-area tandem certified 30.23%, first through 30%
- Constraint~80% after 1000h light; area scaling tax; shipments still ~100 MW class
Production tandem efficiencies 26.5–28%, certified through 30%. Company cost still ~RMB 1/W above c-Si. 20-year depreciation vs 3–5-year tech life—terminal value untrustworthy, hence low PB.
