The evolution of the solar Photovoltaic (PV) industry so far has been remarkable, with several milestones achieved in recent years. Intensive research is searching for high efficiency solar cells with low-cost fabrication. The main problem for solar cell is relatively low efficiency of absorption of solar light. This work reports on a method concerning the improvement of the performance of Dye Sensitized Solar Cell (DSSC) power conversion efficiency (PEC) by using gold nanoparticles (NPs) as an additive to the natural dye extracted from blue honeysuckle berries (BHBs) (Lonícera caeruléa) to increase absorption of solar light. The optical absorption spectra of reversed micellar solutions (RMS) NPs gold (Au) and dye from BHBs are obtained and studied. The solar cell’s performance in terms of efficiency (voltage vs. current) was tested under an indoor room light and fluorescent lamp. Absorption spectrum from UV-Vis spectrophotometer shows that RMS NPs Au solution with a BHBs dye (with a volume proportion of 1: 1) the intensity of a narrower band with an apparent λmax ~ 540 nm increases significantly, which is significantly greater than 10 times the intensity of optical absorption of the entire volume of RMS NPs Au. The DSSC with RMS AuNPs solution with a BHBs dye exhibited 47.48% increase in PEC as compared to DSSCs without RMS AuNPs.. The experimental results presented in this paper demonstrate that DSSCs prepared with AuNPs possess the higher efficiency than DSSCs without NPs.
