Article Synopsis
  • The text discusses the challenges of achieving ideal bandgaps for double-junction tandem solar cells and highlights how Cu(In,Ga)Se (CIGSe) can closely match the desired bandgap of 1.00 eV by adjusting its composition.
  • It describes a method to improve the open circuit voltage by introducing Ga gradients in the absorber layer, which helps mitigate issues like interfacial carrier recombination.
  • The study presents a narrow-bandgap CIGSe solar cell that achieved a record efficiency of 20.26% and emphasizes the importance of controlling gallium diffusion to enhance performance in tandem solar cell applications.
