Impacts of the Mn-ion in the ZnSe Passivation on Electronic Band Structure for High Efficiency CdS/CdSe Quantum Dots Solar Cells

03-Jul-2018 | Shuqi Lu; Shanglong Peng; Zhiya Zhang; Yunlong Deng; Tianfeng Qin; Juanjuan Huang; Fei Ma; Juan Hou; Guozhong Cao, Dalton Transactions, 2018

The surface passivation in quantum dot sensitized solar cells (QDSSCs) plays a very important role in preventing surface charge recombination and thus enhancing the power conversion efficiency (PCE). ZnSe passivation with dopant in CdS/CdSe co-sensitized QDSSCs has been demonstrated an effective ...

Slow surface passivation and crystal relaxation with additives to improve device performance and durability for tin-based perovskite solar cells

26-Jun-2018 | Efat Jokar; Cheng-Hsun Chien; Yu-Hao Chang; Amir Fathi; Mohammad Rameez; Eric Wei-Guang Diau, Energy & Environmental Science, 2018

We investigated the doping effect of bulky organic cations with ethyl diammonium diiodide (EDAI2) and butyl ammonium iodide (BAI) as additives to passivate the surface defects, to control the film morphology and to improve the crystallinity for the inverted planar FASnI3 perovskite solar cells. ...

Potential for improved transport in core–shell CuInS2 nanoparticle solar cells from an Ag surface termination

05-Jun-2018 | Yicong Hu; Rob Patterson; Robert Lee-Chin; Jianghui Zheng; Ning Song; Long Hu; Gavin Conibeer; Shujuan Huang, CrystEngComm, 2018

A major factor limiting the performance of nanostructured CuInS2 photovoltaic devices is the current density, pointing to poor charge carrier transport in CuInS2 nanoparticle films. In a typical CuInS2 core/shell structure synthesis, ZnS is typically chosen as a shell material for CuInS2 core ...

Tunable electronic properties of partially edge-hydrogenated armchair boron–nitrogen–carbon nanoribbons

27-May-2018 | Naresh Alaal; Nikhil Medhekar; Alok Shukla, Physical Chemistry Chemical Physics, 2018

We employ a first-principles calculations based density-functional-theory (DFT) approach to study the electronic properties of partially and fully edge-hydrogenated armchair boron–nitrogen–carbon (BNC) nanoribbons (ABNCNRs), with widths between 0.85 nm to 2.3 nm. Due to the partial passivation of ...

Hybrid perovskite films approaching the radiative limit with over 90% photoluminescence quantum efficiency

30-Apr-2018 | Ian L. Braly; Dane W. deQuilettes; Luis M. Pazos-Outón; Sven Burke; Mark E. Ziffer; David S. Ginger; Hugh W. Hi ..., Nature Photonics, 2018

Reducing non-radiative recombination in semiconducting materials is a prerequisite for achieving the highest performance in light-emitting and photovoltaic applications. Here, we characterize both external and internal photoluminescence quantum efficiency and quasi-Fermi-level splitting of ...
