Panasonic hit solar cells efficiency record
Solar cells HIT (Heterojunction with Intrinsic Thin layer), from Panasonic, reached a new record in terms of energy conversion efficiency â€" 25.6%. The improvement is almost 1%, compared to 24.7% efficiencies attained in February 2013. According to the manufacturer, this is a new record for a crystalline silicon solar cell of "practical".The Panasonic sorts a cell of "practical" as one that has an area greater than 100 square centimetres. The February record of last year was registered to a cell with an area of 101.8 square centimetres. The new record was observed in a device with 143 inches square, referred to Gizmag.However, the Panasonic indicates that this last record is also an improvement over the previous record of 25% efficiency for small cells, about four inches square. Still, these energy efficiency values are below the values recorded for other types of cells, such as the multijunção solar cells and solar cells of triple-compound joint hubs about 38.8% and 44.4% efficiency, respectively.The new record of efficiency achieved by Panasonic was possible due to the development of the properties of hetero-junction technology.Foto: Mountain/\Ash/Creative Commons
