General description

Coumarin 30 (C30) is a laser dye that has a fluorescence yield that tends to unity, which can be potentially used in optical communications and sensors. It is highly stable on the spin coating and shows high quantum efficiency upon low concentration doping.

Application

C30 can form a thin film on p-silicon (p-Si) semiconductor, which can be used to fabricate the aluminum/C30/p-Si based diodes. It can be used as a donor with fluorescein as an acceptor to study the time resolved fluorescence resonance energy transfer (FRET).

Dye-sensitized solar cells (DSCs) are 3rd generation solar cells combining the promise of high efficiency with low production costs.

While dye sensitization as the basis for color photography has been accepted for a very long time,1 attempts to use this principle for the conversion of solar light to electricity generally had resulted only in very low photocurrents, below 100 nA/cm
