چکیده
Synthesis of fullerene oxides[C70(O)n] (n=1~3 or n=1) by fullerene [C70] and several oxidants such as 3-chloroperoxy benzoic acid, chromium(VI) oxide, benzoyl peroxide, trichloroisocyanuric acid take place under microwave irradiation. The MALDI-TOF MS, UV-visible spectra and HPLC analysis confirmed that the products of fullerene oxidation are [C70(O)n] (n=1~3 or n=1).

To model the active layer in the hetero-junction solar cells, the C60, C70, PC60BM, PCBDAN fullerenes as acceptor, and (OS)n=1) oligoselenophenes as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM, and (OS)n=14/PCBDAN blends as a model of the active layer in the BHJ solar cell were chosen, and the optoelectronic properties were studied. The calculated efficiency of these ...
