Dynamics of SiC-nc:Polymer Blend Formation for Hybrid PVs Hybrid solar cells, whose photoactive layer comprises a mixed structure of an organic electron donor and an inorganic electron acceptor, have become of considerable interest as a low cost option for solar energy harvesting. According devices offer the benefits of solution processability, while utilizing the excellent charge transport properties of a crystalline inorganic semiconductor. Silicon carbide nanocrystals (SiC-nc) are an interesting candidate for hybrid photovoltaics. However, due to the specific inert surface, the preparation of stable colloidal solutions involving this material is challenging. Here, we present results on our investigations regarding the stability of dispersed SiC-NCs in polymer solutions, depending on solvent, polymers and their molecular weight. Further, we will show characteristics of resulting thin film formation in terms of film homogeneity, morphology, nanocrystal distibution and optical properties. |
