Summary: The main bottleneck in the development of kesterite Cu2ZnSn(S,Se)(4) (CZTSSe) solar cells is their very low V-OC due to severe carrier recombination. By implementing Cd gradient doping near the front interface during selenization, interface recombination can be significantly reduced, leading to an improved V-OC and higher photovoltaic conversion efficiency.

Summary: This paper reviews the significance of solar photovoltaic (PV) technology and the challenges it faces, such as improving energy efficiency and reducing the use of active materials. The dynamic photo-thermal effect and the optical to electrical energy gap are important issues, which can be addressed through the use of transparent passivation contact materials and thin active layers. It is also crucial to understand how to reduce the near infrared band optical and thermal influence. Several advancement pathways, such as thin wafer-based Si, thin film CdTe, organic and perovskite PV technologies, are reported to minimize energy loss and improve efficiency.

Summary: This study focuses on the hydro-abrasive erosion of the Pelton turbine injector in sediment-laden water. Computational fluid dynamics coupled with discrete element method simulations were used to model the sediment-laden flows, considering particle rotation and collisions. A semi-empirical erosion model was developed to predict the erosion of the injector, which was calibrated with experimental data for turbine steel. The results showed that the erosion of the injector was asymmetric, and the variation in particle size played a major role in the erosion distribution. The nozzle opening conditions had a significant impact on the erosion distribution and the location of maximum erosion on the spear.

Summary: This study investigates the electrical behavior and lifetime differences of organic photovoltaic (OPV) modules installed inside, on the outside of a polytunnel greenhouse roof, and on a fixed frame next to the polytunnel. The aim is to find an installation location that reduces degradation and prolongs the lifetime of OPV modules in a greenhouse application. The degradation rates of the modules are influenced by exposure to weather conditions, mechanical stresses caused by the movement of the greenhouse plastic sheeting, and dust accumulation. Efficiency and fill factor values decrease for modules on top of the polytunnel, inside the polytunnel, and on frames next to the polytunnel. Installing OPV modules inside a tunnel can increase module lifetimes and overall lifecycle output. Avoiding the stresses caused by film movement can further improve OPV lifetimes.

Summary: In this experimental study, the transport of nanoparticles in convective turbulence was investigated. It was found that the joint action of turbulent effects and large-scale circulations, as well as molecular effects, resulted in the accumulation of nanoparticles at the cold wall of the chamber. The mean number density of nanoparticles was observed to decrease exponentially over time. Numerical simulations provided further insights and were in agreement with experimental results.
