6.I-V Curve & Spectral Response
7.Feature:
HIGH PERFORMANCE The monocrystalline solar cells with the extended 5-inch format are 10% more powerful than polycrystalline solar cells.The results from series production have shown a mean efficiency of 18%. Thus solar cell is one of the the most powerfull solar cells worldwide. Our monocrystalline solar cells are among the most efficient on the market. The cells are manufactured and tested for optimum performance and processing characteristics. Cells are sorted according to very narrow current classes and visual appearance criteria. As well as performance testing and categorisation, our quality ontrol procedures also include checking every single cell for mechanical and aesthetic faults. ELECTRICAL PROPERTIES -Very good long-term electrical stability through crystalline silicon technology -Excellent low light behaviour thanks to parallel resistance
-Excellent low light behaviour thanks to parallel resistance checks on every checks on every cell -Narrowest worldwide current classes -Classification into very narrow current classe
Onward Processing Recommendations
