Abstract
- Tin-based perovskites possess the suitable narrow-bandgap for tandem solar cells but their short carrier diffusion lengths limit device efficiency. Here Yang et al. add cadmium ions to increase diffusion length to above 2 µm by reducing the background free hole concentration and electron trap density.
