“…Eventually, the presence of the crystallites on the unmodified MoO x surface can lead to a sub-optimal contact between the HTL and the photoactive layer, decreasing the output characteristics (and more specifically J sc ). A similar effect was observed by Qin et al, as they reported a decrease in efficiency and short-circuit current density due to the suboptimal roughness of the ZnO electron transporting layer in an OPV with inverted architecture [52]. In this study, a decrease in output characteristics was observed from the moment the RMS roughness of the interface layer exceeded 7 nm, which is also the case for the unmodified MoO x HTL.…”

The identification, fine-tuning, and process optimization of appropriate hole transporting layers (HTLs) for organic solar cells is indispensable for the production of efficient and sustainable functional devices. In this study, the optimization of a solution-processed molybdenum oxide (MoOx) layer fabricated from a combustion precursor is carried out via the introduction of zirconium and tin additives. The evaluation of the output characteristics of both organic photovoltaic (OPV) and organic light emitting diode (OLED) devices demonstrates the beneficial influence upon the addition of the Zr and Sn ions compared to the generic MoOx precursor. A dopant effect in which the heteroatoms and the molybdenum oxide form a chemical identity with fundamentally different structural properties could not be observed, as the additives do not affect the molybdenum oxide composition or electronic band structure. An improved surface roughness due to a reduced crystallinity was found to be a key parameter leading to the superior performance of the devices employing modified HTLs.

“…Metal oxides, such as zinc oxide (ZnO) and titanium oxide (TiO 2 ), with high electronmobility, efficient electron-extraction, and good hole-blocking capacity, have been widely used as the cathode interfacial layer. [19][20][21][22] Although the operational stability under air has been improved for the inverted PSCs, these cells still suffer from the inherent incompatibility and poor electrical contact at the interface between the inorganic metal oxides and polymer based photoactive layer. 23 In order to further lower the energy barrier for electron-transport and reduce the inherent incompatibility between the metal oxide and conjugated polymer based photoactive layer, the water soluble polymer electrolytes or conjugated polymer electrolytes have been coated on the top of metal oxide layer or blended with the metal oxide, and used as the electron-selective layer of inverted PSCs.…”

“…The ZnO sol‐gel was spined onto Co at different rpms (2000–6000) in the glove box. [ 21,49,50 ] Then, the PTB7‐Th (donor, D) and PC 71 BM (acceptor, A) were purchased from 1‐Material Chemscitech Inc. (Canada). The active layer solutions (D/A ratio 1:1.5) with polymer concentrations of 15 mg mL −1 were prepared in 1,2‐dichlorobenzene (ODCB) with 3% (volume fraction) of 1,8‐diiodooctane (DIO).…”

The inexorable trend of spintronics is to develop efficient spin-control methods. For example, photovoltaic spintronics driven by sunlight has great potential in energy-saving applications. Here, a ferromagnetic/PV heterojunction is prepared on Si-substrate as Ta (4 nm)/Co (1 nm)/ZnO (from 10 to 58 nm)/ PTB7-Th: PC 71 BM/Pt (3 nm) to study how visible light affected magnetic dynamics. A linewidth variation as high as 812.55 Oe is achieved by optimizing the thickness of ZnO film used to enhance the electron transfer. Due to the photovoltaic effect, reversible ferromagnetic resonance (FMR) linewidth switches are displayed, which is attributed to the 3d orbitals occupancy of Co induced the TMS contribution and inhomogeneous broadening. This work proposes a sunlight controllable magnetic damping heterostructure for developing fast, small, energy-efficient spintronics applications.
