Fourth generation high-efficiency polycrystalline technology:
After improving the ingot-casting furnace, Hareon Solar reduced the transverse temperature difference, obtained a flatter surface on the wafers, improved the columnar crystal quality, and lowered the dislocation density of the silicon ingots. Concurrently, the special structure of the DS heat convection will increase the liquid convection and reduce the sediment. As a result of improving the ingot casting, the cell’s conversion efficiency has improved by 0.1%.
Conventional Cells & PERC Cells:
As a result of improving the diffusion, coating, and metallization processes combined with the superior structure of PERC cells and black silicon technology, Hareon Solar achieved increases in cell efficiencies of more than 0.5%;
Inkjet Printed Cells:
By integrating inkjet-printing technology, PERC cells can be made with less paste and achieve a conversion efficiency of over 21%.
N-Type Bifacial Cells: By using optimized processes to combine complex materials, Hareon Solar produced n-type bifacial cells with efficiencies of greater than 20.5% and 19% on the front and back side respectively.
High-efficiency module development:
Hareon Solar plans to improve the module power-output by about 5W in 2016 by utilizing new technology, such as increasing back-sheet reflectivity, split PV junction boxes, half-cell PV modules, high-transmittance antireflection glass, multi-main busbar technology, and EVA wavelength conversion.
Targeted Product Development:
Hareon utilized its advanced manufacturing technology and selected appropriate BOMs to create reliable PV modules for specific climatic conditions and applications. For example, nonmetal frame modules can be used in maritime regions where there is higher air humidity and salinity, whereas modules with resistance to wind erosion, ultraviolet aging, and low temperature coefficients are more suitable for desert regions.
