Summary: Organic Photovoltaics (OPV) is a promising technology for powering IoT devices with artificial illumination. OPVs can achieve efficiencies as high as 30.2% under warm white LED light and show remarkable stability under indoor illumination. A study on cost-effective ITO-free cell stack with absorber materials processed from non-halogenated solvents has achieved efficiencies up to 21% with outstanding stabilities. Further efficiency increase can be expected with a wide range of potential organic semiconducting materials.

Summary: The impact of surface modification by insulating polymers on the ultraviolet-enhanced conductivity of non-atomically doped ZnO films is investigated. Polymer modifiers rich in amino and hydroxyl groups are effective in increasing the concentration of oxygen vacancies and the conductivity of the films. The highest conductivity achieved is over 1000 S cm(-1) using polyethylenimine ethoxylated as the modifier for NAD-ZnO films. Replacement of ITO in organic photovoltaic devices with a ZnO/PEIE electrode is successfully realized, and the devices exhibit comparable or better performance than ITO-based devices.

Summary: Semitransparent organic photovoltaics (ST-OPVs) have attracted attention for their high power generation, thermal insulation, and aesthetic features. However, traditional optical evaluation only focuses on transmission properties and ignores reflection behaviors. In this study, an optical microcavity architecture was introduced into ST-OPVs to achieve high transmittance homogeneity and controllable reflection by tuning the thickness of individual layers. A set of parameters was proposed to quantitatively describe the optical characteristics.

Summary: Recently, the power conversion efficiencies of two-component, single-junction organic solar cells processed in a glove-box have exceeded 18%. However, their mass-scale manufacture using roll-to-roll coating techniques in an air-free environment is not practical. From a commercialization perspective, efficient air-processed organic solar cells are of greater interest. By controlling the crystallinity of non-fullerene acceptors, air-processed organic solar cells with outstanding power conversion efficiencies have been achieved.

Summary: Insight into the identity and origin of defects in organic semiconductors is crucial for targeted strategies to overcome them. The study focuses on PM6:Y6 organic solar cells and reveals that defects are formed by a trace constituent in ambient air and O-3. Aging in H2O-saturated compressed air also increases the defect response by modifying the work function of MoO3. Measurement of energy resolved-electrochemical impedance spectroscopy and different cell structures confirm that defects mainly originate from PM6 and are located near the top electrode.

Summary: Photoinduced halide segregation limits the widespread application of three-dimensional mixed-halide perovskites. In this study, we investigate the phenomenon of photoinduced halide segregation in lower-dimensional mixed iodide-bromide perovskites. We find that layered two-dimensional structures exhibit additional stability against halide demixing due to reduced halide mobility, which is supported by solid-state NMR analysis.

However, interfacial materials are typically developed for specific cell architectures. We have demonstrated the exceptional performance of a small molecule as a hole transporting layer (HTL) in both n-i-p and p-i-n perovskite solar cells, thanks to its self-assembling properties. This study highlights the advantages of hydrogen bonded HTLs in terms of charge extraction and recombination, regardless of the cell architecture.
