Solar energy with an' ironclad future'

Solar energy plays an important role in the fight against climate change as a substitute for fossil fuels. Dye-sensitized solar cells promise to be a low-cost supplement to the photovoltaic systems we know today. Their key feature is the dye sensitizers attached to their surface. Researchers continue to improve the performance with sensitizers using iron -- a commonly available and environmentally friendly metal.
