WebAug 13, 2012 · Poly (3-hexylthiophene) (P3HT) (Rieke Metals, average molecular weight: 50 000, Fig. 1 (a) for chemical structure) and PCBM (Solenne BV, Fig. 1 (b) for chemical structure) were dissolved in chlorobenzene (10 mg/ml) separately. Bottom gate, top contact OFET device structure is shown in Fig. 1 (d). Webwas disappeared after spin-coating PCBM as shown in Fig. 2(b).Y. Yang, et al. reported that lower molecular weight P3HT is dissolved by the solvent of PCBM, that is, , and P3HT fine DCM structure disappears [10]. In the report, P3HT with high molecular weight more than 25K g/mol is not dissolved. However, the molecular weight of P3HT WebDec 1, 2011 · For cells prepared from P3HT: PCBM blends, the used weight ratio is mostly close to 1. The solution is thereby less saturated in PCBM and then the solubility is less critical. Mostly, the reported arguments took into account the evaporation rate of solvent during the process of deposition. csu library columbia southern
