    • closedAccess   Effect of Light Illumination on Mixed Halide Lead Perovskites: Reversible or Irreversible Transformation 

      Huang, Weixin; YOON, SEOG JOON; Sapkota, Pitambar American Chemical Society (2018)
      One intriguing aspect of mixed halide lead perovskites (e.g., CH3NH3PbBrxI3–x) is halide ion segregation when subjected to visible illumination, but this aspect gives rise to the concerns regarding the influence of halide ...

    • openAccess   Laser-Reduced BiVO4 for Enhanced Photoelectrochemical Water Splitting 

      Barawi Morán, Mariam; Gomez-Mendoza, Miguel; Oropeza, Freddy E; Gorni , Giulio; Villar-Garcia, Ignacio J.; Gimenez, Sixto; de la Peña O'Shea, Víctor Antonio; García-Tecedor, Miguel American Chemical Society (2022-07-27)
      The present study proposes a laser irradiation method to superficially reduce BiVO4 photoelectrodes and boost their water oxidation reaction performance. The origin of this enhanced performance toward oxygen evolution ...

    • openAccess   Role of thermally occupied hole states in room-temperature broadband gain in CdSe/CdS giant-shell nanocrystals 

      Tanghe, Ivo; Llusar, Jordi; Climente, Juan I.; Barker, Alex J.; Paternò, Giuseppe Maria; Scotognella, Francesco; Polovitsyn, Anatolii; Khan, Ali Hossain; hens, zeger; Van Thourhout, Dries; Geiregat, Pieter; Moreels, Iwan Wiley (2022)
      Growing CdSe/CdS nanocrystals from a large CdSe core, and employing a giant CdS shell, a continuous, broadband gain spectrum, covering the spectral range between the CdSe and the CdS band edge, is induced. As revealed by ...

    • closedAccess   Toward Efficient Carbon Nitride Photoelectrochemical Cells: Understanding Charge Transfer Processes 

      Albero, Josep; Barea, Eva M; Xu, Jingsan; Mora-Sero, Ivan; García, Hermenegildo; Shalom, Menny Wiley (2016-06)
      Hole extraction is the key! Charge recombination, electron injection and hole extraction rates between C3N4, TiO2, and several electrolytes in a photoelectrode configuration are studied. It is found that the TiO2/C3N4 ...
