The ultra-thin TOPCon solar cell uses dual-sided polysilicon passivated contacts formed by low-pressure chemical vapor deposition. The champion device, with a thickness of only 80 μm, achieved 19.7% efficiency with 719 mV open-circuit voltage and demonstrated strong passivation, optical performance, and mechanical flexibility.

Researchers at NTU Singapore have developed ultra-thin perovskite solar cells about 50 times thinner than conventional designs using a vacuum-based thermal evaporation process.…
