Novel Polymer Can Boost Performance of Organic and Perovskite Solar

As the world tries to transition to clean and renewable energy, such as solar power, scientists are working on making solar cells more efficient at producing electricity. Among the promising approaches are two rapidly developing photovoltaic technologies with potential for inexpensive sustainable solar energy generation: organic solar cells and lead-halide perovskite solar cells.

6G Communications Curious Progress

6G Communications promises between ten to one hundred times the download speed for operating unpowered devices, remote holographic surgery and much more, but it will depend on how high a frequency is chosen and how much infrastructure investment is made.

Will it be Safe for Humans to Fly to Mars?

Sending human travelers to Mars would require scientists and engineers to overcome a range of technological and safety obstacles. One of them is the grave risk posed by particle radiation from the sun, distant stars and galaxies.

Neural Model Seeks 'Inappropriateness" in Chatbots

Researchers have introduced the notion of inappropriate text messages and released a neural model capable of detecting them, along with a large collection of such messages for further research. Among the potential applications are preventing corporate chatbots from embarrassing the companies that run them, forum post moderation, and parental control.

Neural networks will help manufacture carbon nanotubes

Thin films made of carbon nanotubes hold a lot of promise for advanced optoelectronics, energy and medicine, however with their manufacturing process subject to close supervision and stringent standardization requirements, they are unlikely to become ubiquitous anytime soon.

Organic solar cells will last 10 years in space

Over the past two decades, organic solar cells have garnered much attention thanks to their light weight, flexibility and unprecedented energy-to-weight ratios of 10 to 20 W/g, which make them a promising candidate for space applications, although their radiation stability is still poorly

Increasing energy sources for portable electronics

Scientists have proposed a new approach to replacing carbon atoms with nitrogen atoms in the supercapacitor's crystal lattice and developed a novel capacity enhancement method based on carbon lattice modification with the aid of plasma. Their findings can help create the next generation of power sources for portable electronics.

Unleashing perovskites' potential for solar cells

Researchers have been able to decipher a key aspect of the behavior of perovskites made with different formulations: With certain additives there is a kind of "sweet spot" where greater amounts will enhance performance and beyond which further amounts begin to degrade it.
