Metallodieletric photonic crystal are being a great booster in development of light
managing materials. Inverted silica, alloy(Au-Ag) had potential in increasing light
trapping in solar cell. This composite was prepared through self-assembly method
which is simple, fast and low cost that able to fabricate bigger surface area of photonic
crystal. PMMA used as crystal template and hydrolysed TEOS act as cementing
component. MMA monomer is completely undergo polymerization reaction to form
PMMA due to absent of C=C bond around 1639.83 cm -1 characterized by IR
spectroscopy. Alloy(Au-Ag) nanoparticle has good ability to absorb light where UV-Vis
analysis shows the absorption of this nanoparticles at wavelength 437nm. The removal
of PMMA template from Si-Alloy(Au-Ag)-PMMA composite produce inverted structure
where it has hole skeleton structure show by SEM image. The performance of
composite inverted Si-alloy(Au-Ag) was test by using dye sensitive solar cell (DSSC)
where the reading of voltage was increased.
