Highest polymer heterojunctions

X 10 cm (V s ) at Vds= 30 V. These mobilities are the highest balanced mobilities reported so far for solution processed all polymer bulk heterojunction bipolar FETs. The balanced FET mobilities indicate the presence of sufficient percolation pathways for both charge carriers in these polymer blends. 

Xu et al. [78] have synthesized gold (Au)-silica nanorods with shell thickness of 0-10 nm incorporated into the bulk heterojunction of organic solar cell and observed that at optimal (1 wt. %) concentration, Au-silica nanorods with 5 nm shell thickness resulted in the highest power conversion efficiency of 8.29%. A 26% relative enhancement in PCE was observed for a low bandgap polymer fullerene bulk heterojunction (BHJ) device after incorporation of 1% weight ratio of Au-silica nanorods by Xu et al. [79]. A similar enhancement was found when Ag-silica NPs were introduced at the interface of the anode buffer layer and active layer of a polymer fullerene BHJ device by Choi et al. [80]. Yang et al. [81] have developed a novel hole transport layer (HTL) composed of ultrathin two-dimensional, molybdenum disulfide (M0S2) sheets decorated with 20 nm...
