AbstractConversion of energy from photons in sunlight to hydrogen through solar splitting of water is an important technology. The rising significance of producing hydrogen from solar light via water splitting has motivated a surge of developing semiconductor solar-active nanostructures as photocatalysts and photoelectrodes. Traditional strategies have been developed to enhance solar light absorption (e.g., ion doping, solid solution, narrow-band-gap semiconductor or dye sensitization) and improve charge separation/transport to prompt surface reaction kinetics (e.g., semiconductor combination, co-catalyst loading, nanostructure design) for better utilizing solar energy. However, the solar-to-hydrogen efficiency is still limited. This article provides an overview of recently demonstrated novel concepts of nanostructure designs for efficient solar hydrogen conversion, which include surface engineering, novel nanostructured heterojunctions, and photonic crystals. Those first results outlined in the main text encouragingly point out the prominence and promise of these new concepts principled for designing high-efficiency electronic and photonic nanostructures that could serve for sustainable solar hydrogen production.

1-(2-Methacryloyloxy)ethyl-3-butylimidazolium bromide, a kind of functional ionic liquid containing ester group, was synthesized by two synthesis methods, denoted as thermal heating method and ultrasonic-assisted method. The optimal synthesis condition of the thermal heating method is discussed. Comparison of the two methods shows that ultrasound significantly enhances the efficiency of the reaction. The ultrasonic-assisted method is quite promising in synthesis of ionic liquids with mild condition and high efficiency.

Transparent Surface

The transparent surface of low-temperature solar devices is insulated with glass or polyethylene. Ensuring more light penetration from such surfaces ensures efficient operation of the device, in other words, the device has a high efficiency. Selecting the device design to allow most of the sunlight falling on the transparent surface to enter the device, keeping the transparent surface clean, reducing the angle of incidence of the light to small values, and so on. In most cases, it depends on the parameters. In this article, we analyze the theoretical and practical solutions of work related to the selection and optimization of the angle of incidence of light on the transparent surface of the device to increase the incidence of sunlight during the day. Light absorption, rotation and absorotion of light into low- temperature solar cells. Mathematical analysis and formulas are given.

Light absorption in single nanowires (NWs) is one of the most crucial factors for photovoltaic applications. In this paper, we carried out a detailed investigation of light absorption in single rectangular NWs (RNWs). We show that the RNWs exhibit improved light absorption compared with the square NWs (SNWs), which can be attributed to the symmetry-breaking structure that can increase the light path length by increasing the vertical side and the enhanced leaky mode resonances (LMRs) by decreasing the horizontal side. We found that the light absorption in silicon RNWs can be enhanced by engineering the horizontal and vertical sides, the photocurrent is significantly increased by 276.5% or 82.9% compared with that of the SNWs with the same side length as the horizontal side of 100 nm or the vertical side of 1000 nm, respectively. This work provides an effective way for designing high-efficiency single NW photovoltaic devices based on the symmetry breaking from the SNWs to RNWs.
