We report a novel promising semiconductor of Ag3CuS2 serving as absorber material in inorganic-organic solid-state solar cells for the first time, and the device (ITO/ZnO/Ag3CuS2/P3HT/Pt) exhibits a power conversion efficiency of 2.01%. This study opens up an available method to develop various ternary absorber materials for tertiary generation solar cells.

Picosecond pulse propagation through a field-enhanced waveguide bulk semiconductor saturable absorber is studied numerically. Fast switching from unsaturated absorption to delayed strong saturation and gain, as well as the predicted dependence of saturation energy on electric field, is based on intraband carrier kinetics and electric-field dynamics in the absorber and can lead to improved, cont...

The absorption characteristics of porous absorbers in combination with perforated facings was investigated. The effect of the hole size, hole pattern and open area ratio were examined. The absorption coefficients for an absorber of uniform cross-section were compared to those for an absorber with a tapered cross-section for various volumes of absorbent and different perforated facings.

Bicycle configuration is not as large as those of motorcycles or automobiles, while it indeed composes a complicated dynamic system. People’s requirements on comfortability, controllability and safety grow higher as the research and development technologies improve. The shock absorber affects the vehicle suspension performances enormously. The absorber takes the vibration energy and releases it...

ASCA PV observations of the Seyfert 1 galaxy MCG?6?30?15 : rapid variability of the warm absorber. ABSTRACT We present a detailed re-analysis of the two ASCA Performance Veriication observations of the nearby Seyfert 1 galaxy MCG?6?30?15. Connrming the results of Fabian et al. (1994), we nd deenite evidence for the O vii and O viii K-shell absorption edges of the warm absorber and a doubling of...

Hot water supplies account for approximately 30% of energy consumption in residential sectors of Japan; it is therefore important that the energy efficiency of water heaters be improved. Absorption heat pump water heaters are expected to provide greater efficiency than conventional water heaters that use gas. However, the absorption systems have larger volumes and are not widely accepted in the...

We report the results of numerical investigations of the dynamical behavior of a blue-violet InGaN laser with a specially incorporated saturable absorber. We have identified the nature of the bifurcation that occurs in the device dynamics and also the conditions that are necessary for self-pulsating and excitable operations. We also demonstrate the influence of the relevant device parameters on...

This paper investigates the use of an augmented pendulum absorber for damping tower vibrations in monopile-supported wind turbines. A shunted electromagnetic transducer is proposed to replace classic viscous dashpot absorbers, order improve performance and durability absorber. series RCL (resistive-capacitative-inductive) network designed as supplemental shunt transducer, which together with in...
