Tuning Recombination and Charge Separation in a n/p/p Heterojunction Solar Cell with CZTS, Ag3SbS3 and a Carbon Interlayer

An n/p/p heterojunction solar cell taps the synergy between the photosensitizers: CdS (n-type) and CZTS (p-type) nanocrystals and Ag 3 SbS 3 (p-type) quantum dots to yield an efficiency of 9.76%.
