For all the promise they are showing in converting sunlight into electricity at ever-improving efficiencies, perovskite solar cells still have some flaws that must be addressed for them to enter ...

Photo of ultrathin on-chip solar cells. The cells are the green squares and include an ultrathin layer of light-absorbing GaAs, which is key to their radiation tolerance. The surface of each green ...

Researchers at the Ningbo Institute of Materials Technology and Engineering (NIMTE) at the Chinese Academy of Sciences have found a new way to stick different layers of tandem solar cells and achieved ...

Favoring light emission instead of heat dissipation after light absorption.

Some people like to say outer space is a starry frontier of vast emptiness, but clearly they’ve never tried launching a satellite. Sixty-five years after Sputnik, some 8,000 low-Earth orbit (LEO) ...

PV cells are primarily composed of semiconductor materials that have a higher conductivity than insulators. However, these materials are not good conductors of electricity like metals. Different types ...

A new cancer therapy developed by Purdue University researchers attacks tumors by tricking cancer cells into absorbing a snippet of RNA that naturally blocks cell division. As reported Monday (Sept. 4 ...

WASHINGTON, Nov. 8, 2022 – Most space satellites are powered by photovoltaic cells that convert sunlight to electricity. Exposure to certain types of radiation present in orbit can damage the devices, ...

As low Earth orbit becomes more cluttered, it becomes increasingly necessary to use middle Earth orbits, and radiation-tolerant cell designs will be needed. Making photovoltaics thinner should ...
