Product Name: N Type 9bb Mono Bifacial Hjt Solar Cell Model NO.: DS-SC-NHJT09 Material: Monocrystalline Silicon Certification: EST, UL, ISO, CB, CE Condition: New Application: Solar Panel Manufacturing Number of Cells: 1 Piece Warranty: 10 Years Size: 156.75 * 156.75 mm Thickness: 190 +-30 Um Certificate: ISO9001/14001, Ce/TUV Efficiency: 23.2 ~ 23.7 % Trademark: OEM Transport Package: Cartons Specification: HJT Mono Origin: China HS Code: 38180011 Product Description N type 9BB mono bifacial HJT solar cellProduct DescriptionSilicon Hetero Junction Technology (HJT) is based on an emitter and back surface field (BSF) that are produced by low temperature growth of ultra-thin layers of amorphous silicon (a-Si:H) on both sides of very well cleaned mono silicon wafers, less than 200 μm in thickness, where electrons and holes are photogenerated.The cell process is completed by the deposition of transparent conductive oxides that allow for an excellent metallization. The metallization can be done by a standard screen printing which is widely used in industry for the majority of cells or with innovative technologies.Hetero Junction Technology (HJT) silicon solar cells have attracted a lot of attention because they can achieve high conversion efficiencies, up to 25%, while using low temperature processing, typically below 250 °C for the complete process. Low processing temperature allows handling of silicon wafers of less than 100 μm thick while maintaining a high yield.Key featuresHigh Eff and high VocLow temperature coefficient 5-8% power output gainBifacial structuresMore detailsRelated products
