How 'doping' boosts next-gen solar cells towards commercialisation

An international team of researchers has brought a new generation of solar cells a step closer to commercialisation, by showing how sunlight can trigger a 'healing process' in the cells to improve their efficiency and stability.

Fullerenes bridge conductive gap in organic photovoltaics

Organic photovoltaics have achieved remarkably high efficiencies, but finding optimum combinations of materials for high-performance organic solar cells, which are also economically competitive, still presents a challenge. ...

Colloidal quantum dots make LEDs shine bright in the infrared

The ideal optoelectronic semiconductor material would be a strong light emitter and an efficient charge conductor to allow for electrical injection in devices. These two conditions, when met, can lead to highly efficient ...

Ion drive space engine used on aircraft for first time

Imagine an aircraft engine that has no moving parts, produces no harmful exhaust and makes no noise. That's what researchers at the Massachusetts Institute of Technology (MIT) in the US have created by adapting a technology ...

Enhanced power devices open the way for high-voltage applications

Power semiconductors play an important role in power conversion in a wide range of electronic equipment we use in our everyday lives, from smartphones and computers to photovoltaics and electric vehicles. Given the extensive ...
