Paving the Way for Photovoltaic Innovation
In April 2025, LONGi made a groundbreaking announcement at its Wuhu base in Anhui Province, China, showcasing its Hybrid Interdigitated-Back-Contact (HIBC) crystalline silicon solar cell with an impressive efficiency of 27.81%. This achievement not only pushed the boundaries of monocrystalline silicon photovoltaic cells but also opened a new path for improving the power density of photovoltaic modules. The HIBC cell, which was independently developed by LONGI’s Central Research Institute, boasts a dual breakthrough in optical management and carrier transport efficiency. This innovative design enables the efficient transfer of photons and charge carriers, leading to a significant increase in power output.
- By optimizing the structure and material system, LONGI has successfully improved the optical management and carrier transport efficiency of its solar cells, resulting in a more efficient conversion of sunlight into electricity.
- The HIBC cell’s design allows for better light trapping and collection, reducing energy losses and increasing overall efficiency.
Achieving a New Standard in Photovoltaic Efficiency
LONGI’s remarkable achievement not only surpasses its previous world record of 26.81% efficiency in November 2022 but also surpasses the 27.4%, 27.52%, and 27.63% efficiency records set in May 2024. This remarkable progress underscores LONGi’s commitment to continuous innovation and its dedication to pushing the boundaries of photovoltaic technology.
