Durable, high-performing perovskite solar cells also require durable, high-performing charge-transporting layers. Scientists have developed the first organic hole transporter that does not need a dopant to attain high charge mobility and stability. According to the study published in the journal Angewandte Chemie, this novel hole-transporting layer outperforms reference materials and protects the perovskite organic cell from air humidity.
