Scientists here have developed new dye-sensitized solar cells (DSSCs) that get their pink color from a mixture of red dye and white metal oxide powder in materials that capture light.
Currently, the best of these new pink materials convert light to electricity with only half the efficiency of commercially-available silicon-based solar cells -- but they do so at only one quarter of the cost, said Yiying Wu.
