A major breakthrough has been achieved in the solar cell efficiency race. A leading domestic photovoltaic company announced today that its independently developed perovskite-crystalline silicon tandem solar cell has achieved a conversion efficiency of 33.7% under laboratory conditions, once again breaking the world record for similar cells.
This efficiency level far exceeds the ceiling of traditional monocrystalline silicon PERC cells (approximately 24%) and TOPCon cells (approximately 26%). The company stated that it has built a 100-megawatt-scale perovskite pilot line and expects to achieve GW-level mass production by 2027.
Perovskite technology is considered a core direction for next-generation photovoltaics. Its advantages lie not only in high efficiency but also in short process flow, low material cost, and the ability to fabricate flexible modules. However, the industry is also generally concerned about challenges such as long-term stability and uniformity in large-area fabrication. This efficiency breakthrough undoubtedly injects strong confidence into the photovoltaic industry, will further reduce the cost of photovoltaic electricity, and accelerate the transition from “grid parity” to “low-cost grid connection.”
