Enhanced charge transport in low temperature carbon-based n-i-p perovskite solar cells with NiOx-CNT hole transport material

Multi-dynamics and emission tailored fluoroperovskite-based down-conversion phosphors for enhancing the current density and stability of the perovskite solar cells

“…This phenomenon is attributed to stream extra photo-generated carriers from the perovskite absorber, which in turn improved the current density of the device from 21.56 to 23.54 mA cm −2 . Moreover, although numerous studies on PSCs claim the current density of 20 ± 2 mA cm −2 , 14,20,21 our synthesized fluoroperovskite-based DC phosphors enhanced the device current density to 23.54 mA cm −2 , which is 86.5% of the theoretical maximum J sc (27.2 mA cm −2 ). 22 Furthermore, we achieved that the incorporation of RbCaF 3 :Eu 3+ into TiO 2 protects the devices well from UV-oriented degradation, and it is discussed elaborately.…”

Upscaling of Carbon-Based Perovskite Solar Module

“…Formamidinium-based perovskite coupled with Spiro-OMeTAD and pressed LTCE foils demonstrate the biggest efficiency for these devices, above 20% with 1000 h of shelf life stability [ 83 ]. Metal phthalocyanine [ 84 , 85 ], CuSCN [ 86 ], P3HT/NiO x -CNT [ 76 , 87 ], NiO nanoparticles [ 88 ], Cu 2 ZnSnS 4 [ 89 ], and TPDI [ 90 ] are new relevant examples of HTMs employed with a low-temperature carbon electrode. Lately, low-dimension perovskite layers employing large cations like phenethyl ammonium iodide (PEAI) and octyl ammonium iodide (OAI) were used on top of 3D perovskite with LTCEs for interfacial engineering and 2D perovskite growth, with promising efficiencies of 15.6 and 18.5% ( Figure 3 C,D), respectively [ 91 , 92 ].…”

Enhanced electrochemical performance of 3‐D microporous nickel/nickel oxide nanoflakes for application in supercapacitors

“…NiO materials were synthesized by different processing techniques, such as electron beam evaporation, [ 22 ] hydrothermal, [ 24 ] chemical bath deposition, [ 25 ] sol‐gel process, [ 26 ] chemical precipitation, [ 27 ] microwave mediated synthesis, [ 18 ] and electrochemical deposition. [ 28 ] Compared to other processing methods, electrodeposition has multiple advantages, namely, the low cost and precise control on the resulting nanostructures' shape, size, thickness, and mass loading. [ 29–32 ]…”
