Perovskite Photovoltaics: Hope for Next-Generation Solar Technology
Perovskite solar cells, with their excellent potential for photoelectric conversion efficiency and low manufacturing costs, are regarded as strong contenders for next-generation photovoltaic technology. In 2026, perovskite PV modules are transitioning from laboratory to industrialization.
Continuous Efficiency Breakthroughs
Single-junction perovskite cell lab efficiency has exceeded 26%, while perovskite-silicon tandem cells have surpassed 33.9%. Domestic companies like GCL Perovskite, Microquanta, and UtmoLight have made significant progress in large-area module efficiency, with 100cm²-level modules exceeding 18% efficiency.
Core Challenges for Commercialization
Stability Issues: Perovskite materials are sensitive to moisture, oxygen, light, and heat; long-term stability remains the biggest bottleneck. The industry goal is to extend module lifespan to over 25 years through encapsulation materials and interface engineering.
Large-Area Fabrication: There is a significant efficiency gap between lab-scale devices and large-area modules (efficiency cliff effect). Scaling up processes like slot-die coating and vacuum evaporation is key to industrialization.
Lead Leakage Risk: Perovskites contain lead, raising environmental safety concerns. Lead-free perovskite (e.g., tin-based) R&D progress is slow; encapsulated barrier solutions are the current mainstream approach.
Supply Chain Opportunities
The perovskite PV industry chain upstream materials include perovskite precursors (lead iodide, methylammonium iodide, etc.), TCO conductive glass, water/oxygen barrier encapsulation materials, POE/EVA encapsulants, etc. Among these, TCO glass and barrier encapsulation materials have high technical barriers and represent weak links in the domestic supply chain.
