Alkylated Fullerene Derivatives for Solution-Processable Organic Thin-Film Transistors and Bulkheterojunction Solar Cells
In this paper, we report synthesis and characterization of alkylated fullerene derivatives for solution-processable organic thin film transistors and solar cells. Their physical, thermal, and semiconducting properties have been studied. Organic thin-film transistors fabricated from
C60TH-Oc exhibit electron mobilities as high as 3.2×10−2 cm2 V−1 s−1 with 32 V of a threshold voltage. The best power conversion efficiency (PCE) was observed in a layered structure P3HT:C60TH-Oc
(PCE = 0.44%), which was a twice value of P3HT:C60TH-Dd (PCE = 0.23%).
