LONGi Sets New World Record with Over 28 Percent PV Cell Efficiency

The global solar energy landscape is witnessing a historic milestone as Chinese photovoltaic giant LONGi Green Energy Technology has achieved a groundbreaking power conversion efficiency of 28.13 percent with its silicon solar cells. This technological breakthrough, powered by their proprietary Hybrid Interdigitated Back-Contact technology, commonly known as HIBC, has also enabled the corresponding solar modules to surpass an unprecedented 26 percent efficiency mark. This achievement sets a new world record for both single-junction solar cells and modules, pushing the practical limits of silicon-based photovoltaics closer to their theoretical maximums.

To understand the significance of this development, it helps to examine the underlying architecture. The HIBC technology is a highly sophisticated combination that merges Heterojunction technology with Back-Contact architecture. By integrating a composite passivation layer with a back-contact structure, LONGi has successfully eliminated front-side electrode shading. This structural innovation allows the cell to absorb a significantly higher volume of sunlight. Simultaneously, the advanced passivation layers minimize electron recombination, maximizing the overall electrical output.

The industry implications of this breakthrough are profound. As the solar sector transitions away from standard Tunnel Oxide Passivated Contact cells, LONGi's HIBC technology positions itself as a dominant next-generation contender. Higher cell and module efficiency translate directly into greater power output per square meter. For utility-scale and distributed solar installations alike, this means reduced balance-of-system costs, including land use, wiring, and structural support, thereby lowering the levelized cost of electricity and accelerating the global transition toward sustainable energy.
