Remote Trap Passivation in Colloidal Quantum Dot Bulk Nano-heterojunctions and Its Effect in Solution-Processed Solar Cells

More‐efficient charge collection and suppressed trap recombination in colloidal quantum dot (CQD) solar cells is achieved by means of a bulk nano‐heterojunction (BNH) structure, in which p‐type and n‐type materials are blended on the nanometer scale. The improved performance of the BNH devices, comp...

description More‐efficient charge collection and suppressed trap recombination in colloidal quantum dot (CQD) solar cells is achieved by means of a bulk nano‐heterojunction (BNH) structure, in which p‐type and n‐type materials are blended on the nanometer scale. The improved performance of the BNH devices, compared with that of bilayer devices, is displayed in higher photocurrents and higher open‐circuit voltages (resulting from a trap passivation mechanism).
