Dye-sensitized solar cells achieve over 10% yields

With a 10.2% energy conversion yield versus 6% for the previous generation, the dye-sensitized solar cells developed by INAC researchers have set a new standard. Their solar cells use organic dyes with an absorption coefficient some three times greater than those used in conventional dye-sensitized solar cells. And their organic dyes don’t contain ruthenium, an expensive rare metal that can generate toxic chemical derivatives.
The 10.2% yield was achieved during tests carried out by two joint venture partners, and places INAC’s dye-sensitized solar cells among the most efficient in the world. They are also remarkably stable, with no observable deterioration after 2,000 hours of accelerated aging.
The researchers also used their dyes in a novel electrode material developed by a South Korean laboratory, with a performance here again close to the state of the art.
