title: Evaluation of Small Molecules as Front Cell Donor Materials for High-Efficiency Tandem Solar Cells.
abstract: Three small molecules as front cell donors for tandem cells are thoroughly evaluated and a high power conversion efficiency of 11.47% is achieved, which demonstrates that the oligomer-like small molecules offer a good choice for high-performance tandem solar cells.
