# Tandem Solar Cells LONGi Sets a New Perovskite-Silicon Efficiency Record By Mursal Rahman | Written with AI assistance | Published 2026-07-28 | Tech Source: Trend Hunter, https://www.trendhunter.com/trends/Tandem-solar-cells References: [engadget](https://www.engadget.com/2218081/chinese-solar-cell-efficiency-35-5-percent/) & [longi](https://www.longi.com/en/news/crystalline-silicon-perovskite-tandem-solar-cell-new-world-efficiency-2026/)  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](https://www.trendhunter.com/trends/rajasthan-updates), reduce balance-of-system costs and enhance the value of [utility-scale, commercial and residential solar projects](https://www.trendhunter.com/trends/utility-solar-projects). As tandem photovoltaic technology moves closer to [mass production](https://www.trendhunter.com/trends/Solar-manufacturing-infrastructure), manufacturers that successfully scale production may strengthen their competitive position while accelerating the global transition to more efficient clean energy systems.
