Researchers at the Politecnico di Torino in Italy have sought to quantify the potential positive effects of radiative coolers made of cement paste on the performance of photovoltaic cells. These ...

Researchers from The Hong Kong Polytechnic University (PolyU) have achieved a breakthrough power-conversion efficiency (PCE) of 19.31% with organic solar cells (OSCs), also known as polymer solar ...

Ionization and dielectronic recombination are pivotal processes in the study of highly charged ions, underpinning much of modern plasma physics and astrophysics. Ionization involves the removal of one ...

Hong Kong Polytechnic University researchers have developed a binary organic solar cell (OSC) with a record power conversion efficiency of 19.31%. They invented a non-monotonic intermediate state ...

The absolute internal quantum efficiency (IQE) of indium gallium nitride (InGaN) based blue light-emitting diodes (LEDs) at low temperatures is often assumed to be 100%. However, a new study has found ...

Bipolar high-voltage devices based on silicon carbide (SiC) have been earmarked as the next big step in the development of more efficient power systems. The efficiency of these devices is largely ...
