چکیده مقاله:
In this work, in order to model the active layer in the bulk hetero-junction solar cells, the fullerene structures such as C60, C70, PC60BM, PCBDAN as acceptor and oligoselenophenes ((OS)n=14) as donor were considered. The (OS)n=14/C60, (OS)n=14/C70, (OS)n=14/PC60BM and (OS)n=14/PCBDAN blends (complexes) as a model of the active layer in the BHJ solar cell were chosen and the opto-electronic properties were studied. Results show the width of the absorption spectrum of all investigated blends in the range of 400-700 nm and maximum wavelength in the range of 516.65 ˗ 536.03 nm. Base on obtained data the calculated efficiency of these blends based on Scharber diagram was obtained namely 8% and 8.2% respectively.
