摘要:The LID defect in CZ silicon consists of substitutional boronatom and stagger type oxygen dimer.The LID defect in mc silicon is related to the metalimpurities or their aggregation at the structural defects.Regeneration treatment is a good way to eliminate the LIDdefects.Electronic injection by forward bias is an economicindustrial way for the elimination of LID defects.
摘要:YINGLI PADAN N-PERT bifacial cells have already reachedefficiency of 22.81%, and 20.63% on rear side.YINGLI PANDA module with excellent anti-LID performanceprovides 10% - 30% output gain compared to monofacial moduledepending on ground reflective conditions.The 50MW Top-runner Program project in Datong is developedand constructed by Yingli. The energy yield can be increased by~17%.
摘要:The reflectivity reaches the lowest point at a right texturization time.Both large and small pyramid sizes lead to similar reflectivities.Nonuniform flow leads to nonuniform distribution of pyramid size.Wafer with SDR absorbs greater amount of additive than rough wafer.Enhancing the basicity of solution increases cleaning efficiency.The residue of additive on the textured wafer increases while applying SDR. A possible explanation could be that the wafer with arough surface reacts violently with KOH, releasing a large amount of H2, which hindering the absorption of additive to the wafer surface.
摘要:LoRa technology has been used for many industry.It has lower power consumption and Longer Range (8km).Sky Trackeris the 1sttracker to use LoRa.Base on big data server including weather and topography and so on. Give out the control method for Bifacial tracking system:Sunny day—Current control method;Cloudy day—sun-eye mode;Heavy cloudy day—back+front mode;0.5%~2% yield increase.
