The enhancement effect of optical absorption with core-shell gold nanoparticles on the surface wafer-based silicon photovoltaic devices has been studied. obvious enhanced photocurrent is observed, especially when wavelength above 800 nm, and highest value about 14% around 1100 nm. simulation results indicate that presence dielectric coating shell could improve plasmon based scattering at longer range, which provides a good understanding experiment results.
Drought is one of the main adverse factors affecting growth and development wheat. The molecular regulation pathway Strigolactone (SLs or SL),which induces drought resistance in wheat, needs to be further clarified. In this study, SL Tis (Strigolactone inhibitor) were sprayed on leaves clarify changes wheat their effect antioxidant enzyme activity, photosynthesis other metabolic processes. However, 20 kinds DOF transcription identified by transcriptome metabolome association analysis, they...
