The surface plays an important role in thin silicon solar cells, especially with regard to the surface state and interface electronic properties that influence the electron and hole to recombine. In order to keep the recombination loss at a tolerable minimum and avoid an unacceptably large efficiency loss when moving towards thinner silicon materials, the surface must be electronically wellpassivated. Passivation is the most significant step for the functionalization of silicon. In this study, Si functionalization with a dye molecule might increase the absorption of light that acts as light-harvesting material on the silicon surface. Two types of dye molecular were used; DiL (λpeak = 549 nm) and DiO (λpeak = 484 nm). Both dyes were deposited using a spin-coating technique. These dye layers on the silicon surface were characterized using a Kelvin probe (KP) and photoluminescence (PL) spectroscopy. A different mechanism of slow charge trapping and detrapping was observed using KP meas...
