A self-powered heart monitor taped to the skin

Scientists have developed a human-friendly, ultra-flexible organic sensor powered by sunlight, which acts as a self-powered heart monitor. Previously, they developed a flexible photovoltaic cell that could be incorporated ...

Introducing high-performance non-fullerene organic solar cells

Organic solar cells (OSCs) has driven their efficiencies to above 10 percent to reach a viable level for commercialization. However, the increase in the photoactive layer thickness has resulted in lower efficiency levels, ...

How to build efficient organic solar cells

Organic solar cells, made from carbon-based materials, present unique advantages compared with other solar cell technologies. For example, they can be manufactured through low-cost printing technologies, and they can be made ...

Future cities could be lit by algae

The way we produce light has changed surprisingly little since Thomas Edison developed the first light bulb in 1879.

Serious shortcomings in aging tests of new solar cell materials

Researchers at Aalto University have found that only a fraction of stability tests done on new types of solar cells meet proper requirements. Tests lack common standards and should have been done in real-world conditions ...
