New class of solar cells, using lead-free perovskite materials

Lead-based perovskites are promising materials for low-cost and high-efficiency solar cells. However, the intrinsic instability and the toxicity of lead (Pb) have raised serious concerns of the viability of Pb-based perovskites, ...

New light shed on intensely studied material

The organic polymer PEDOT is one of the world's most intensely studied materials. Despite this, researchers at Linköping University have now demonstrated that the material functions in a completely different manner than ...

Power stations driven by light

Green plants, algae and some bacteria use sunlight to convert energy. The pigments in chlorophyll absorb electromagnetic radiation, which induces chemical reactions in electrons. These reactions take place in the nucleus ...

Scientists develop promising new type of polymer

Organic polymers are used in solar cells, sensors, LEDs and in many other devices. One specific type of polymer, S-PPV, was previously regarded as promising in theory, but almost impossible to produce from a technical perspective. ...

Doubling the efficiency of organic electronics

Researchers from Chalmers University of Technology, Sweden, have discovered a simple new tweak that could double the efficiency of organic electronics. OLED-displays, plastic-based solar cells and bioelectronics are just ...

A solution to fracture for durable solar cells

Micro cracks in solar cells are a frequent challenge for manufacturers of solar photovoltaic modules. EU-funded researchers introduced an innovative pre-stressing technique to retard the growth of cracks and make durable ...
