Latest Patent Applications
Erik Gabrielsson has submitted a patent application titled "HIGH EFFICIENCY DYE-SENSITIZED SOLAR CELLS." This application explores the use of cobalt polypyridine complexes as alternative redox mediators for large-scale manufacturing of DSCs. The research examines the impact of steric properties of triphenylamine-based organic sensitizers and cobalt polypyridine redox mediators on electron lifetime and overall device performance. The findings indicate that matching the steric bulk of the dye and redox mediator minimizes recombination and mass transport issues in DSCs. The study highlights that the best efficiency achieved with cobalt(II/III) tris(2,2'-bipyridyl) matches the highest efficiencies obtained with iodide-free electrolytes, reaching a 6.3% overall conversion efficiency under AMI.5 conditions and an efficiency of 7.8% at 1/10 of a sun. This research suggests that organic dyes with high extinction coefficients can replace standard ruthenium sensitizers to create thin-film DSCs, addressing mass transport and recombination limitations associated with cobalt redox couples.
Conclusion
Erik Gabrielsson's work in the field of dye-sensitized solar cells represents a significant advancement in solar technology. His innovative approach to using cobalt polypyridine complexes could lead to more efficient and effective solar energy solutions.
