Dye-sensitized solar cells (DSSCs) have taken up broad interest as a promising low-cost solar cell technology since they were first reported on in 1991.1 DSSCs use specialized materials for specific cell functions such as photon absorption, charge separation, and charge transport. Triiodide then diffuses to the cathode and is reduced back to iodide, which in turn can diffuse back to the photoanode and continue the cycle. A primary reason for the success of the iodide/triiodide mediator is that electron transfer from the photoanode to triiodide is slow, reducing recombination in the solar cell. To advance performance and lower cost, incorporation of new materials and processing techniques is actively pursued. For instance, organic dyes, which avoid the use of rare earth metals, have been developed which have extinction coefficients an order of magnitude greater than the traditional ruthenium complexes.

Embodiments of the present invention relate to graphene-based microphone diaphragms. In one embodiment, a acoustic wave sensor comprises a diaphragm comprised of a graphene-based composition, wherein the diaphragm has a first side at least partially covered with a reflective material. An emitter fiber is positioned proximate to the diaphragm, wherein the emitter fiber transmits light towards the first side. A collector fiber is positioned proximate to the diaphragm, wherein the collector fiber captures at least a portion of light reflected by the first side, wherein the collector fiber is in communication with a detector. A converter is in communication with the detector and converts a signal received by the detector to a digital signal for processing. The portion of light that is captured as a result of diaphragm distortion is different than the portion of light captured in the absence of diaphragm distortion. The graphene-based composition includes graphene sheets.
