Ultrafast transient infrared spectroscopy for probing trapping states in hybrid perovskite films
Halide-based perovskite films are popular absorber materials used in solar cells, but undesired effects such as charge recombination and trapping continue to cap record conversion efficiencies. Here, the authors use femtosecond transient mid-infrared spectroscopy to elucidate electron recombination...

| Summary: | Halide-based perovskite films are popular absorber materials used in solar cells, but undesired effects such as charge recombination and trapping continue to cap record conversion efficiencies. Here, the authors use femtosecond transient mid-infrared spectroscopy to elucidate electron recombination and trapping in the conduction bands of various compositions of perovskite thin films. |
