Panasonic Module Achieves World's Highest Energy Conversion Efficiency of 23.8%
文章附图
Panasonic Corporation today announced that it has achieved a photovoltaic module conversion efficiency of 23.8% (aperture area : 11,562 cm²) at research level, a major increase over the previous world record for crystalline silicon-based photovoltaic modules.
The previous record for the conversion efficiency of a crystalline silicon-based photovoltaic module was 22.8%. Panasonic has broken the record for the world highest conversion efficiency by a full percentage point. Panasonic holds the world records of conversion efficiency for both crystalline silicon-based solar cells and modules.
Panasonic developed a unique silicon heterojunction structure composed of crystalline silicon substrate and amorphous silicon layers, and has continuously improved its photovoltaic module HIT™ using silicon heterojunction since the start of commercial production. This new record was achieved by further development of Panasonic's proprietary heterojunction technology for high-efficiency solar cells and modules adopting a back-contact solar cell structure.
Going forward, Panasonic will continue to pursue technology development of its photovoltaic module HIT™, aimed at realizing higher efficiency, higher reliability and lower costs, and will work towards mass production.
