What is it about?
The lifetime of organic (polymer) solar cells is still a hurdle for commercialization. In the case of high efficiency polymer solar cells, their stability is too poor to say about lifetime at the moment. The reason can be ascribed to the degradation of organic components (conjugated polymers) by the UV light included in the sun light. This paper reports that the stability (lifetime) of polymer solar cells can be significantly improved by cutting the UV light.

Why is it important?
The significantly enhanced stability reported here delivers the increased possibility to commercialize polymer solar cells. In addition, this report suggests the state-of-the-art design for plastic solar modules.
Perspectives
We hope that the present result could be usefully applied for other types of next-generation solar cells. We are happy to make collaborations in terms of solar cell stability and device structures as the efficiency is now exceeding >11%.
