Background

Perovskite and tandem cells are expected to dominate the next generation of photovoltaic technologies. Perovskite single-junction solar cells, with advantages such as semi-transparency, flexibility, and indoor power generation capabilities, hold broad application prospects in fields like BIPV, consumer electronics, wearable devices, and new energy vehicles. Perovskite-perovskite tandem cells and perovskite-Si tandem cells, due to their significantly higher efficiency compared to single-junction cells, are particularly suitable for centralized power station.

Driven by the collaborative efforts of global enterprises and research institutions, perovskite solar cells continue to advance in terms of efficiency, cost, yield rate, stability, and large-scale production. In May 2025, the steady-state power of a 2.82m² perovskite module produced by Utmolight GW-scale production line reached 480.5W, with an efficiency of 17.04%. In September 2025, RenShine Solar's 30cm*40cm flexible perovskite module achieved a steady-state efficiency of 20.84%. In October 2025, GCL Perovskite's GW-scale perovskite production line officially produced its first 1150×2400mm perovskite module.

Perovskite industry leaders and crystalline silicon giants are actively engaged in the research and development of tandem cells. In April 2025, Longi's independently developed perovskite-Si 2T tandem cell achieved an efficiency of 34.85%. In June 2025, Trina Solar's perovskite-Si 2T tandem module once again broke the world record for power output, reaching 841W. In August 2025, the "Square-Meter Class Perovskite/TOPCon 4T Tandem Module and Its Hundred-Megawatt-Level Production Process", developed with the participation of Microquanta, was included in the public announcement list for the fifth batch of the "First Set" Major Technology Equipment in the energy sector.

Tandem cells face more technical challenges compared to single-junction perovskite cells, requiring continuous R&D investment and process optimization. 4T tandem cells have good compatibility and lower manufacturing difficulty, and are expected to achieve mass production first. However, their structure is complex and cost is higher. 2T tandem cells have the compact structure, lower cost and smaller optical losses. Yet, their manufacturing process is more challenging, and issues like current matching still need to be resolved. Meanwhile, perovskite-BC 3T tandem cells, with their unique performance characteristics, are beginning to attract significant industry attention.

8^th Perovskite & Tandem Solar cell Forum 2026 will be held on April 15-16th in Changzhou, Jiangsu, China. The conference will address the following topics: Outlook for the PV industry and market analysis of perovskite & tandem solar cells. Material systems, manufacturing processes, and key equipment for large-area perovskite solar cells. Research on yield and efficiency improvement, cost reduction, and stability of perovskite and tandem Solar Cells. Technology R&D and structural design of tandem solar modules. Applications of perovskite and tandem solar cells in BIPV, consumer electronics, wearable devices, new energy vehicles, distributed and centralized power plants.
