Perovskite solar cells: Vacuum process may offer a short track to commercialization      (via sciencedaily.com)     Original source 

Which process is best suited for mass production of perovskite solar cells? While solvent-based manufacturing processes are used in laboratories around the world, vacuum vapor-phase deposition processes are still the standard for the production of thin films for photovoltaics or organic light-emitting diodes. A new study that reveals major differences in the scientific discussion of these production processes.

Ancient ice may still exist in distant space objects, researchers find      (via sciencedaily.com)     Original source 

A new paper presents findings about the Kuiper Belt Object 486958 Arrokoth, shedding new light on the preservation of volatile substances like carbon monoxide in such distant celestial bodies. The research uses Arrokoth as a case study to propose that many Kuiper Belt Objects -- remnants from the dawn of our solar system -- could still retain their original volatile ices, challenging previous notions about the evolutionary path of these ancient entities.

How to upcycle low-energy light      (via sciencedaily.com)     Original source 

To combine two low-energy photons into one high-energy photon efficiently, the energy must be able to hop freely, but not too quickly, between randomly oriented molecules of a solid. The discovery provides a much-needed design guideline for developing materials for more efficient PV cells, displays, or even anti-cancer therapies.

You don't need glue to hold these materials together -- just electricity      (via sciencedaily.com)     Original source 

Is there a way to stick hard and soft materials together without any tape, glue or epoxy? A new study shows that applying a small voltage to certain objects forms chemical bonds that securely link the objects together. Reversing the direction of electron flow easily separates the two materials. This electro-adhesion effect could help create biohybrid robots, improve biomedical implants and enable new battery technologies.
