Perovskite Manhole Cover
(REF: S-2025) |
| Trial Project |
|
| Solution Feature |
- Integrates perovskite PV with manholes to solve sensor power issues; single manhole generates 50-80kWh annually.
- Innovative seed-induced growth technology enables the efficiency of 300×300mm² perovskite modules to exceed 20%.
- Interface copolymerization enhances stability; efficiency retention >90% at 85℃/85%RH for 1000h.
- Micro-nano texture layer balances R9/R12 slip resistance and power efficiency for manhole scenarios.
- Modular integrated power supply system can support the 24-hour operation of 3-5 sensors without the need for battery replacement.
|
| Trial Application and Expected Outcome |
- Produce 515×1040 mm² manhole prototypes at HKUST and Hong Kong Science Park labs via pilot platform.
- Conduct accelerated aging per IEC 61215 to verify 3000h performance under Hong Kong’s climate.
- Install prototypes at EMSD-designated roads; test for 2 months to monitor power-sensor compatibility.
- Commission HKAS for electrical/slip/fire safety certifications to meet Hong Kong road standards.
- Standardize parameters and use automated equipment to control batch errors for stable module production.
