A simple new approach to plastic solar cells

Humankind is in the midst of a massive drive to harness solar energy to power our homes, gadgets, and industry. Plastic solar cells, based on blends of conducting organic polymers, are of interest for making lightweight and ...

Killing bacteria by hacking plastics with silver and electricity

Researchers at the Swedish Medical Nanoscience Center at Karolinska Institutet have developed an innovative way of hacking conducting plastics so as to prevent bacterial growth using silver nanoparticles and a small electrical ...

New model for the origin of grid cells

Ludwig Maximilian University of Munich neurobiologists present a new theory for the origin of the grid cells required for spatial orientation in the mammalian brain, which assigns a vital role to the timing of trains of signals ...

X-ray vision reveals how polymer solar cells wear out

Scientists from the Technical University of Munich have used the acurate X-ray vision provided by DESY's radiation source PETRA III to observe the degradation of plastic solar cells. Their study suggests an approach for improving ...

New technique opens up advanced solar cells

In a photovoltaic cell, light generates opposite charges in the active layer. The charges must then be separated as quickly as possible to keep them from recombining. Positive charges are driven by a built-in electric field ...

Scientists find a new dopant for organic electronic devices

A team of the Lomonosov MSU researchers in collaboration with their German colleagues from the Institute of Polymer Research in Dresden (Leibniz Institute) believe a particular molecule could lead to the development of organic ...

Record efficiency with tandem solar cells

On Thursday Alice Furlan receives her PhD for her study in which she experimented with stacking different types of material layers in flexible, thin solar cells. By combining these with a thin layer of silicon into a 'tandem ...
