Journal ArticleDOI
Improving carrier extraction in a PbSe quantum dot solar cell by introducing a solution-processed antimony-doped SnO2 buffer layer
Zihan Chen,Zhilong Zhang,Zhilong Zhang,Jianfeng Yang,Weijian Chen,Weijian Chen,Zhi Li Teh,Dian Wang,Lin Yuan,Jianbing Zhang,John A. Stride,Gavin Conibeer,Robert Patterson,Shujuan Huang +13 more
TL;DR: In this paper, a solution-processed trivalent antimony-doped tin oxide buffer layer at the interfaces in the PbSe colloidal quantum dots (QDs) was introduced, which led to significant improvement in the short-circuit current densities.
Journal ArticleDOI
Spectroscopic Insight into Efficient and Stable Hole Transfer at the Perovskite/Spiro-OMeTAD Interface with Alternative Additives.
TL;DR: In this article, the authors investigated charge carrier and mobile-ion dynamics at the perovskite/Spiro-OMeTAD interface, where the Spiro OOmTAD contains different bis(trifluoromethanesulfonyl)imide (TFSI) salts additives (Li-TFSI, Mg-TFI2, Ca-TFSi2, Li-TF SI2) and showed that the hole mobility and conductivity of hole transport layers play an important role in suppressing mobileion accumulation at the interfaces of solar cells.
Journal ArticleDOI
Visualizing the Impact of Light Soaking on Morphological Domains in an Operational Cesium Lead Halide Perovskite Solar Cell.
Thi-Hai-Yen Vu,Weijian Chen,Xiaofan Deng,Cho Fai Jonathan Lau,Shujuan Huang,Anita Ho-Baillie,Baohua Jia,Xiaoming Wen +7 more
TL;DR: This work provides a full picture of the photogenerated process in an operating PSC and therefore guides the design and operation of perovskite-based optoelectronic devices.
Journal ArticleDOI
Manipulating the Fate of Charge Carriers with Tungsten Concentration: Enhancing Photoelectrochemical Water Oxidation of Bi2WO6
Hoi Ying Chung,Hoi Ying Chung,Cui Ying Toe,Weijian Chen,Xiaoming Wen,Roong Jien Wong,Roong Jien Wong,Rose Amal,Fatwa F. Abdi,Yun Hau Ng +9 more
TL;DR: In this article, a plate-like Bi2 WO6 thin film with distinct particle sizes and surface area of different exposed facets is successfully prepared via hydrothermal reaction and it is proposed based on the results from conductive atomic force microscopy that higher tungsten concentration plays a crucial role in facilitating the charge transport of the thin film.
Journal ArticleDOI
Efficient Energy Funnelling by Engineering the Bandgap of a Perovskite: Förster Resonance Energy Transfer or Charge Transfer?
Zhixing Gan,Zhixing Gan,Weijian Chen,Chunhua Zhou,Liyan Yu,Lifeng Dong,Baohua Jia,Xiaoming Wen +7 more
TL;DR: A spectroscopic method is developed to unveil the energy funnelling mechanism by comparing and modelling the photoluminescence spectra excited by pulsed and continuous-wave (CW) lasers and reveals that charge transfer is the dominant mechanism forEnergy funnelling in the FAPbBr3/FAPb(BrxI1-x)3/fAPbI3 sandwich MP.
