Enhancing the electrical performance of formamidinium perovskites through WS2 nanotubes incorporation
Formamidinium-rich lead-halide perovskites combine strong optical absorption with low-temperature solution processing, but limited electrical conductivity can hinder charge extraction in optoelectronic devices. We investigate a composite approach in which hollow tungsten disulfide (WS2) nanotubes synthesized by a high-...
