TL;DR: In this paper, a comparative study has been performed on two ex-situ and one in-Situ doping of titania photoanodes with reduced graphene oxide, and it was found that in-suite doping, i.e. introduction of graphene oxide in solution together with titania precursor was the most performant case of graphene doping.

TL;DR: In this paper, structural evolution of zirconia (ZrO2) thin films which are produced by a sol-gel dip coating process on the 316L stainless steel substrates were investigated at different temperatures.
Abstract: In this paper, structural evolution of zirconia (ZrO2) thin films which are produced by a sol–gel dip coating process on the 316L stainless steel substrates were investigated at different temperatures. Microstructural features and phase transformations of the synthesized thin films were characterized by Fourier transform-infrared spectroscopy (FT-IR), thermogravimetric/differential thermal analysis (TG/DTA), X-ray diffractometry (XRD), scanning electron microscopy (SEM) and atomic force microscopy (AFM). The FT-IR, TG/DTA and XRD analysis results, in a good agreement, indicated that the adopted production route led to the formation of a surface tetragonal zirconia (t-ZrO2) film with high crystallinity at 700 °C. The formed tetragonal phase was transformed to monoclinic zirconia phase (m-ZrO2) at 900 °C. Corrosion performance of the heat treated ZrO2 films was evaluated through potentiodynamic polarization tests and electrochemical impedance spectroscopy (EIS) in 1-M H2SO4 solution at 80 °C. The results demonstrated that the treated thin film at 500 °C had the strongest corrosion barrier performance on the 316L stainless steel. The SEM images showed a crack-free uniform film with an average thickness of 155 nm on the surface can be obtained. Moreover, AFM investigations also showed that the average roughness of the coated films increased with the rising heat temperature.

TL;DR: The "graphene interface engineering" (GIE) strategy enables MAPbI3-based PSCs to achieve a PCE up to 20.12% (average PCE of 18.8%) and the possibility to combine quantum and chemical effects into GIE, coupled with the recent success of graphene and GRMs as interfacial layer, represents a promising approach for the development of next-generation P SCs.
Abstract: Interface engineering of organic–inorganic halide perovskite solar cells (PSCs) plays a pivotal role in achieving high power conversion efficiency (PCE). In fact, the perovskite photoactive layer needs to work synergistically with the other functional components of the cell, such as charge transporting/active buffer layers and electrodes. In this context, graphene and related two-dimensional materials (GRMs) are promising candidates to tune “on demand” the interface properties of PSCs. In this work, we fully exploit the potential of GRMs by controlling the optoelectronic properties of molybdenum disulfide (MoS2) and reduced graphene oxide (RGO) hybrids both as hole transport layer (HTL) and active buffer layer (ABL) in mesoscopic methylammonium lead iodide (CH3NH3PbI3) perovskite (MAPbI3)-based PSCs. We show that zero-dimensional MoS2 quantum dots (MoS2 QDs), derived by liquid phase exfoliated MoS2 flakes, provide both hole-extraction and electron-blocking properties. In fact, on one hand, intrinsic n-typ...

TL;DR: In order to improve the stability of PCSs, various inorganic hole transporting materials (HTMs) have been developed and applied into PSCs, which has achieved a certified PCE of 22.7% as mentioned in this paper.
Abstract: Organic–inorganic hybrid perovskite solar cells (PSCs) have received considerable attentions due to their low cost, easy fabrication, and high power conversion efficiency (PCE), which achieved a certified PCE of 22.7%. To date, most of high efficiency PSCs were fabricated based on organic hole transporting materials (HTMs) such as molecular spiro-MeOTAD or polymeric PTAA. However, poor stability of PSCs limits its large scale commercial application because of use of additives like tert-butylpyridine (t-BP) and lithium salt. Moreover, relatively low-temperature degradation of organic HTMs is responsible for poor thermal stability of PSCs. Consequently, HTM play a crucial role in realization of efficient and stable PSCs. In order to improve the stability of PCSs, various inorganic HTMs have been developed and applied into PSCs. Recently, the devices based on CuSCN and Cu:NiOx HTMs have demonstrated PCEs over 20%, which is comparable to PCEs of devices based on organic HTMs. Most importantly, stability of PC...
