Photo voltaic panel innovator LONGi lately reached two know-how milestones. First, its hybrid interdigitated-back-contact (HIBC) photo voltaic cell was licensed by the Institute for Photo voltaic Vitality Analysis Hamelin (ISFH) in Germany, reaching a photoelectric conversion effectivity of 28.13%. Second, modules utilizing HIBC photo voltaic cells have been licensed by the U.S. Nationwide Laboratory of the Rockies (NLR), with effectivity reaching 26.4%.
Each are record-breaking efficiencies for silicon-based photo voltaic cells and panels.
As the last word answer for single-junction crystalline silicon cell know-how, the HIBC cell developed by LONGi’s Central R&D Institute launched core applied sciences resembling in-situ Patterned Edge Passivation (iPET) and Laser-Induced Crystallization modification (LIC). Via systematic optimization of structural design, materials choice and fabrication processes, LONGi says it has achieved a number of breakthroughs in optical efficiency, interface passivation high quality, and cost transport effectivity, paving a mature pathway for the business deployment of ultra-high-efficiency crystalline silicon cells.
LONGi had previously described its HIBC cells as incorporating heterojunction technology, which mixes the very best qualities of crystalline silicon with these from amorphous silicon thin-film to supply a high-power hybrid cell.
