24% efficient topcon-based back contacted polyzebra solar cells

HIGHLIGHTS

  • What: The group with improved capping showed higher cell efficiencies, but nevertheless, all results of this study are compared to the control group of last year`s publication. The wafers used in this study were thinner as-delivered with 150 μm compared to 175 μm before. This effect is mostly responsible for the reduction of pFF-to-FF loss between last year`s publication and this study as presented in Figure 3.
  • Who: Jonathan Linke and colleagues from the International Solar Energy Research Center Konstanz e.V. , Rudolf-Diesel-Str., Konstanz , Germany have published the . . .
