Organic semiconductor-based nanoparticles with long-lasting reactive charges

Due to their advantageous properties, organic semiconductors could be very promising photocatalysts for producing solar fuels. In fact, these materials can be synthetically tuned to absorb visible light, while simultaneously retaining energy levels that are desirable for driving various processes. While photocatalysts based on organic semiconductors have attained promising results, the understanding of the physics underpinning their functioning is still relatively limited.Due to their advantageous properties, organic semiconductors could be very promising photocatalysts for producing solar fuels.

Solar nanowire-nanotube filter offers easy access to clean drinking water

Even today, clean water is a privilege for many people around the world. According to the World Health Organization (WHO), at least 1.8 billion people consume water contaminated with feces, and by 2040, a large portion of the world will endure water stress because of insufficient resources of drinking water. Meanwhile, according to the United Nations Children’s Fund (UNICEF), around 1,800 children die every day from diarrhea because of unsafe water supply, which causes diseases like cholera.Even today, clean water is a privilege for many people around the world.

A bright future: Seeking a third generation of better-performing solar cells

For a greener and more sustainable economy, building better and more powerful solar cells is a key research goal within the clean energy sector. But, in a typical single-junction solar cell, performance is capped at what is called the Shockley–Queisser limit (a theoretical limit for the maximum efficiency that a solar cell can reach). Efficiency determines how much of the light energy (photons) absorbed by the solar cell can be converted into usable electric current. The Shockley–Queisser limit puts the maximum possible efficiency at 33.7 percent for semiconductor-based solar cells.For a greener and more sustainable economy, building better and more powerful solar cells is a key research goal within the clean energy sector.
