Hybrid Solar Cells From Silicon Nanocrystals and Conductive Polymers
Keyword(s):
Hybrid solar cells based on blends of a conjugated polymer, poly-3(hexylthiophene) (P3HT), and silicon nanocrystals (Si NCs) have been developed and characterized. The properties of composite Si NCs/P3HT films which were spun from 1, 2-dichlorobenzene were studied. Under A.M. 1.5 direct illumination conditions (100mW/cm2), devices made with 50wt% 3–5nm Si NCs showed 1.33% power conversion efficiency (PCE) and had a 30% incident-photon-to-current conversion efficiency at 470 nm.
