“…Generally, semiconducting behavior is observed for most p-type TCs such as delafossites (7,8,18), layered oxychalcogenides (12), and perovskite Sr-doped LaCrO 3 (19), which show thermally activated conductivity near room temperature and variablerange hopping at low temperatures due to the strong localization of carriers. In contrast, the transport properties of the p-type CuI thin films reported here are quite unusual, as can be seen from the temperature (T) dependence of the conductivity (σ) in Fig.…”

“…A larger value of FOM indicates better performance of the TC. Due to the absent R values in most studies, the FOM is usually simplified by the approximation R = 0 and using FOM ∼ −1/(R s lnT vis ) (19). As shown in Fig.…”

“…To date, the highest conductivity of a p-type TC is ∼220 S/cm for Mg-doped CuCrO 2 , however at the cost of low visible transmittance down to ∼30% (18). Recently, perovskite Sr-doped LaCrO 3 has been reported as a novel p-type TC, exhibiting a moderate conductivity of ∼54 S/cm; however, the transmittance of 42.3% is still fairly low (19). Results on p-type TCs from the literature are summarized in Table S1.…”

A degenerate p-type conduction of cuprous iodide (CuI) thin films is achieved at the iodine-rich growth condition, allowing for the record high room-temperature conductivity of ∼156 S/cm for asdeposited CuI and ∼283 S/cm for I-doped CuI. At the same time, the films appear clear and exhibit a high transmission of 60-85% in the visible spectral range. The realization of such simultaneously high conductivity and transparency boosts the figure of merit of a p-type TC: its value jumps from ∼200 to ∼17,000 MΩ −1 . Polycrystalline CuI thin films were deposited at room temperature by reactive sputtering. Their electrical and optical properties are examined relative to other p-type transparent conductors. The transport properties of CuI thin films were investigated by temperature-dependent conductivity measurements, which reveal a semiconductor-metal transition depending on the iodine/argon ratio in the sputtering gas.copper iodide thin film | p-type transparent conductor | figure of merit | reactive sputtering | room-temperature growth

“…In related work cationic and anion substitution and the role of Cr vacancies in this material has been studied. [66,67] High conductivity has also been shown experimentally in non-Cu metal oxides, most notably spinel-structured TCOs, such as NiCo 2 O 4 , [68,69] perovskites-structured TCOs, such as SrIn x Ti 1-x O 3 and Sr x La 1-x CrO 3 , [70,71] and amorphous or composite oxides, such as ZnO·Rh 2 O 3 and In:MoO 3 . [72,73] Other oxides, such as doped Cr 2 O 3 and Ba 2 BiTaO 6 , have promise but remain to be synthesized with high conductivities.…”

With the development of new generations of optoelectronic devices that combine high performance and novel functionalities (e.g., flexibility/bendability, adaptability, semi or full transparency), several classes of transparent electrodes have been developed in recent years. These range from optimized transparent conductive oxides (TCOs), which are historically the most commonly used transparent electrodes, to new electrodes made from nano‐ and 2D materials (e.g., metal nanowire networks and graphene), and to hybrid electrodes that integrate TCOs or dielectrics with nanowires, metal grids, or ultrathin metal films. Here, the most relevant transparent electrodes developed to date are introduced, their fundamental properties are described, and their materials are classified according to specific application requirements in high efficiency solar cells and flexible organic light‐emitting diodes (OLEDs). This information serves as a guideline for selecting and developing appropriate transparent electrodes according to intended application requirements and functionality.

A solid‐state photoelectrochemical cell is operated between 400 and 500 °C under 365 nm UV light. The cell consists of a photovoltaic part, based on a La0.8Sr0.2CrO3/SrTiO3 junction, and an electrochemical part including a zirconia solid electrolyte with a shared (La,Sr)FeO3 electrode. The photovoltaic cell part leads to open circuit voltages up to 920 mV at 400 °C. Upon UV light, this driving force is used in the electrochemical part of the cell to pump oxygen from low to high partial pressures, i.e., to convert radiation energy to chemical energy. This demonstrates the feasibility of high‐temperature photoelectrochemical cells for solar energy storage. The detailed characterization of the different resistance contributions in the system by DC and AC methods reveals the parts of the cell to be optimized for finally achieving high‐temperature photoelectrochemical water splitting.
