Splet26. jun. 2013 · A selective solvent vapor, i.e., cyclohexanone or isopropyl benzene, which is a poor solvent for poly(3-hexylthiophene-2,5-diyl) (P3HT) and a good solvent for fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester (PCBM), was employed to reduce the size of PCBM aggregates and prolong the formation time of big PCBM aggregates in … SpletThe solubility of lead iodide (PbI 2), Methyl ammonium iodide (MAI), and PCBM in organic solvents is limited, especially after the incorporation of PCBM. Therefore, in the preparation of doping solution, PCBM is stirred first and dissolved with N,N-Dimethyl formamide (DMF) and Dimethyl sulfoxide (DMSO) mixed solvent, and then perovskite ...
PCBM is the common abbreviation for the fullerene derivative [6,6]-phenyl-C61-butyric acid methyl ester. It is being investigated in organic solar cells. PCBM is a fullerene derivative of the C60 buckyball that was first synthesized in the 1990s. It is an electron acceptor material and is often used in organic solar cells (plastic solar cells) or flexible electronics in conjunction with electron donor materials such as P3HT or other conductive polymers. … SpletA series of novel benzo [1,2-b:4,5-b′]-dithiophene (BDT)-based conjugated polymers were synthesized using a Stille cross-coupling reaction.
