The compound that makes chili peppers spicy also boosts perovskite solar cell performance
Research publishing January 13 in the journal Joule, determined that sprinkling capsaicin, the compound that makes peppers spicy, into the precursor of methylammonium lead triiodide (MAPbI3) perovskite during the manufacturing process led to a greater abundance of electrons (instead of empty placeholders) to conduct current at the semiconductor's surface. The addition resulted in polycrystalline MAPbI3 solar cells with the most efficient charge transport to date. (2021-01-13)

Most distant quasar discovered sheds light on how black holes grow
A team of astronomers led by the University of Arizona has observed the most distant quasar to date.

A polarization-driven guide to making high-performance, versatile solar cells
When solar cells are exposed to sunlight, certain bound ''charge pairs'' are generated in its components, which need to be separated for photocurrent generation. Ferroelectric materials, due to their spontaneous electric polarization, are highly efficient at charge separation but do poorly in light-to-electricity conversion. Now, scientists from Korea have demonstrated using theoretical calculations that antiperovskite oxides, a class of ferroelectric materials, show large absorption of sunlight, making them suitable photoabsorbers for thin film solar cells.

In plants, channels set the rhythm
Like animals, plants have 'molecular switches' on the surface of their cells that transduce a mechanical signal into an electrical one in milliseconds. In animals, sound vibrations activate 'molecular switches' located in the ear. French scientists have found that in plants, rapid oscillations of stems and leaves due to wind may activate these 'switches' very effectively. They could allow plants to 'listen' to the wind.
