Location >> LONGi Sets New World Record with 35.5% Efficient Perovskite-Silicon Tandem Cell: A New Breakthrough in Solar Technology
Date：2026-07-20
Recently, Chinese renewable energy company LONGi (LONGi Green Energy) announced that its independently developed perovskite-silicon tandem solar cell (Perovskite-Silicon Tandem Cell) has achieved a 35.5% power conversion efficiency, certified by an authoritative testing organization, setting a new world record for this technology route.
This breakthrough represents a major milestone in next-generation high-efficiency photovoltaic technology and provides new opportunities for the future development and upgrading of the solar industry.
What is a Perovskite-Silicon Tandem Solar Cell?
Traditional crystalline silicon solar cells are approaching their theoretical efficiency limits. Tandem solar cells overcome these limitations by combining the advantages of two materials:
1、Perovskite Material: Improves high-energy spectrum utilization
2、Silicon Technology: Maintains mature industrial infrastructure and stable performance
By integrating both technologies, tandem cells can achieve higher solar conversion efficiency and are expected to become one of the key technology pathways for future high-efficiency photovoltaic modules.
Why Does This Matter?
-Increase solar power generation capacity per unit area
-Reduce land requirements for large-scale solar projects
-Drive the PV industry toward higher efficiency and lower costs
-Accelerate integration between solar energy, energy storage, and smart energy systems
Industry Trend: Next-Generation Solar Technologies Are Accelerating
As the global energy transition continues, the photovoltaic industry is moving from large-scale expansion toward technology-driven innovation. The combination of perovskite tandem technology, high-efficiency solar modules, and energy storage systems will become an important direction for the future renewable energy industry.
Industry Link: ASEE 2027
