Summary: The use of a bilayer ZnO/MgO ETL instead of a single ZnO ETL improves power conversion efficiency in organic photovoltaic devices by reducing leakage current and enhancing electron extraction efficiency. Insertion of a thin MgO interlayer in the devices effectively reduces leakage current and increases shunt resistance. This approach increases short circuit current density and fill factor, leading to a 10% increase in power conversion efficiency for organic photovoltaics.

Summary: This study demonstrates experimentally a flexible crystalline silicon solar cell based on dopant-free interdigitated back contacts (IBCs) with a thickness of merely 50 μm for the first time. By using a MoOx thin film to cover the front surface, the power conversion efficiency (PCE) is boosted to over triple that of the uncoated solar cell. The front MoOx film functions for both antireflection and passivation, contributing to the excellent performance.

Summary: Layered semiconducting transition metal dichalcogenides (TMDs) have excellent optoelectronic properties, but practical contacts to TMDs have poor charge carrier selectivity, leading to low open-circuit voltage (V-OC) and limited power conversion efficiency (PCE). A simple MoOx (x approximate to 3) surface charge-transfer doping and passivation method was applied to multilayer tungsten disulfide (WS2) solar cells to address these issues, resulting in lateral p-n junction photovoltaic cells with a record V-OC of 681 mV, the highest among all p-n junction TMD solar cells with a practical design, and leading to record PCE in ultrathin (<90 nm) WS2 photovoltaics.

Summary: Halide perovskite based solar cells have shown great potential due to their easy fabrication technique and low cost. The quality and crystallinity of the perovskite film play a crucial role in the efficiency and performance of the solar cell. Semitransparent perovskite solar cells have attracted attention for their application in tandem solar cells, but face challenges in transparent rear electrodes and optimization techniques. This study fabricates high quality perovskite films using a double-sided sandwich evaporation technique and demonstrates improved photovoltaic performance compared to the traditional spin-coating method.

Summary: Infrared detection technology has been widely applied across various fields. This study explores the application of the hot carrier effect from nanometer thickness of metal for mid-infrared and far-infrared detection. The research findings indicate that the physical characteristics of metal surfaces, such as coverage, thickness, and stress, play a crucial role in the hot carrier optical detection. Higher metal coverage leads to increased optical response, while thicker metal surfaces result in longer conversion time of hot carriers and degradation in signal due to their short lifetime. Additionally, a film with the best hot carrier effect in the Cr/Si structure is able to detect an infrared signal up to 4.2 μm, with a significant improvement in signal-to-noise ratio (SNR) compared to less favorable conditions.

Summary: Silicon-based photodetectors are promising for low-cost and eco-friendly optical sensing, especially in silicon photonics systems. However, extending their optical responsivity to the mid-IR range remains a challenge. In this study, we demonstrate the use of a passivated surface layer to mitigate the Fermi-level pinning effect in metal-insulator-semiconductor contacts, effectively reducing the Schottky barrier height. The resulting devices exhibit high responsivity and detectivity, enabling application development in future silicon photonics integration platforms.

Summary: Measuring specific contact resistivity (pc) is crucial for interface engineering in high efficiency solar cells. The Transfer Length Method (TLM) is commonly used for evaluating layer sheet resistance (Rsheet) and pc, but it is not suitable for metal/Transparent Conductive Oxide (TCO) interface evaluation in silicon heterojunction (SHJ) cells. This study investigates the parameters that restrict current confinement within the TCO, including mid-gap trap density (Dit) at the a-Si:H/c-Si interface and the activation energy (Ea = Ec - EF) variation of a-Si:H contact layers.

Summary: The phenomenon of ribbon lengthening in PV modules exposed to thermal cycling is not well explained in the literature. In this study, a three layers model is proposed to explain this effect, and the predictions of the model are validated through finite element method simulations and experiments. The results show that the model predictions are consistent with the indirect measurements, but not with the direct measurements. Additionally, it is inferred that the encapsulant plays a role after the solder failure.

Summary: This study found that decorating subwavelength arrays with SiO2 quasi-nanolenses (qNL arrays) can enhance the absorption of the solar spectrum. Optical absorption mechanisms in qNL arrays were investigated using near-field scanning optical microscopy (NSOM), revealing that the enhancement is a result of the combination of effective antireflection coating, increased optical interactions between adjacent dielectrics for elevated light trapping, and strong light concentration due to the presence of qNLs.
