R&D on High-Stability 2D/3D Hybrid Perovskite Solar Cells and Their Application in Smart Manhole Cover Power Supply Systems

I&T Solution	R&D on High-Stability 2D/3D Hybrid Perovskite Solar Cells and Their Application in Smart Manhole Cover Power Supply Systems (REF: S-2026)
Trial Project
Solution Feature	2D/3D perovskite structure mitigates moisture- and heat-induced degradation. Hydrophobic cation protection + efficient interfacial transport enhance stability. Manhole encapsulation + anti-slip design integrate PV with ground (R9/R12). Adapted for manhole PV: low height, traffic load, underground humidity. Smart sensing + energy management enable monitoring, perception, wireless safety.
Trial Application and Expected Outcome	Successfully fabricated 2D/3D perovskite modules operating >2000 h (85% RH, 60 °C). Encapsulation meets manhole anti-slip R9/R12; PV prototype tested outdoors. Provides clean energy for manhole sensors, reducing battery and power costs. Enhances public facility intelligence and drives perovskite PV industrialization. Aligns with Hong Kong’s “carbon neutrality” and “energy efficiency” targets.
