A Chinese research team has investigated impurity and defect levels in solar cells based on mono cast wafers and have found that around 30% of the devices present an "excessive" reduction in power conversion efficiency. The scientists concluded that cast monocrystalline silicon will unlikely capture a meaningful market share in the near future. Researchers from Zhejiang University in China have investigated the impact of impurities and defects on the performance of solar cells built with mono cast silicon (CM-Si) wafers and have found that only around 70% of the cells produced with this material ...Den vollständigen Artikel lesen ...
