Efficient Solar Cells via Green, and Sustainable Coating Technique

Preparation of CdIn2S4-CdS nanocomposite via a green route and using them in dot-sensitized solar cells for boosting efficiency

In this work In2S3 and CdS nanoparticles were prepared by a simple hydrothermal method and then annealed at 500 °C for 2 h in an Ar gas until CdIn2S4(CdIS)-CdS nanocomposites were formed. Afterwards, efficiency of the as-synthesized CdIS-CdS nanocomposite in quantum dot-sensitized solar cells (QDSSCs) was evaluated. For this purpose, the as-prepared CdIS-CdS nanocomposites were deposited on TiO...

Sustainable and efficient biohydrogen production via electrohydrogenesis.

Hydrogen gas has tremendous potential as an environmentally acceptable energy carrier for vehicles, but most hydrogen is generated from nonrenewable fossil fuels such as natural gas. Here, we show that efficient and sustainable hydrogen production is possible from any type of biodegradable organic matter by electrohydrogenesis. In this process, protons and electrons released by exoelectrogenic ...

Green Concrete: An Efficient and Eco-Friendly Sustainable Building Material

Green concrete is a concept of thinking environment into concrete considering every aspect from raw materials manufacture over mixture design to structural design, construction and service life. Green concrete is a type of concrete which resembles the conventional concrete but the production or usage of such concrete requires minimum amount of energy and causes least harm to the environment. Si...

Printing efficient solar cells

As worldwide demand for fossil fuels depletes reserves, scientists are increasingly focused on generating alternative energy— especially if it can be produced cleanly and inexpensively. Hydroelectric, solar, wind, nuclear, and biomass technologies are replacing coal, oil, and natural gas. Many of these new technologies have similar costs. Yet the availability of materials or existing infrastruc...
