Superabsorbing fullerenes

Fullerene bisadducts are promising electron-accepting materials because of the increased open-circuit voltage of BHJSCs based on these compounds compared with those based on PCBM. That led researchers to synthetize C60 bisadducts connected with the strong absorber perylenediimide (PDI) in a cyclic fashion.

Scientists produce a novel form of artificial graphene

A new breed of ultra thin super-material has the potential to cause a technological revolution. 'Artificial graphene' should lead to faster, smaller and lighter electronic and optical devices of all kinds, including higher performance photovoltaic cells, lasers or LED lighting.

The ultimate miniaturization of lamps: a single-molecule LED

The ultimate challenge in the race to miniaturize light emitting diodes (LED) has now been met: researchers have developed the first ever single-molecule LED. The device is formed from a single polythiophene wire placed between the tip of a scanning tunneling microscope and a gold surface. It emits light only when the current passes in a certain direction.

Light-induced degradation in amorphous silicon thin film solar cells

Researchers have taken a leap forward towards a deeper understanding of an undesired effect in thin film solar cells based on amorphous silicon - one that has puzzled the scientific community for the last 40 years. The researchers were able to demonstrate that tiny voids within the silicon network are partly responsible for reducing solar cell efficiency by some 10 to 15 percent as soon as you start using them.
