Tandem Solar Cells

LONGi Sets a New Perovskite-Silicon Efficiency Record

Tandem solar cells are advancing photovoltaic performance by combining crystalline silicon with perovskite materials to capture a broader range of sunlight and achieve higher conversion efficiencies than conventional solar cells. LONGi's latest certified 35.5% efficiency milestone demonstrates the continued progress of this next-generation technology, while larger cell and module results indicate growing readiness for commercial-scale production. The company's ongoing improvements highlight the industry's focus on increasing energy output without significantly expanding panel size.

For businesses, higher-efficiency tandem solar cells could improve the economics of renewable energy by generating more electricity from the same installation footprint. This can lower land-use requirements, reduce balance-of-system costs and enhance the value of utility-scale, commercial and residential solar projects. As tandem photovoltaic technology moves closer to mass production, manufacturers that successfully scale production may strengthen their competitive position while accelerating the global transition to more efficient clean energy systems.
