Passivation Using Molecular Halides Increases Quantum Dot Solar Cell Performance

© 2015 WILEY-VCH Verlag GmbH & Co. KGaA, Weinheim. Here we report a solution-based passivation scheme is developed featuring the use of molecular iodine and PbS colloidal quantum dots (CQDs). The improved passivation translates into a longer carrier diffusion length in the solid film. This all...

Here we report a solution-based passivation scheme is developed featuring the use of molecular iodine and PbS colloidal quantum dots (CQDs). The improved passivation translates into a longer carrier diffusion length in the solid film. This allows thicker solar-cell devices to be built while preserving efficient charge collection, leading to a certified power conversion efficiency of 9.9%, which is a new record in CQD solar cells. 2018-12-11T02:49:49Z 2019-03-14T08:01:33Z 2018-12-11T02:49:49Z 2019-03-14T08:01:33Z 2016-01-13 Article Advanced Materials.
