Novel hole tranpsort material for Perovskite solar cells

Ulm University

A novel spiro-configured hole transporter was synthesized and developed which contributed to efficiencies over 21% and increased long-term stability in Perovskite solar cells. The results are described in our recent publication in ACS Applied Energy Materials 2020, 3, 7456-7463 with the title „Cyclopentadithiophene-Based Hole-Transporting Material for Highly Stable Perovskite Solar Cells with Stabilized Efficiencies Approaching 21%“.
