A new and effective planar D-π-A configured small organic molecule (SOM) of 2-5-(3,5-dimethoxystyryl)thiophen-2-yl)methylene)-1H-indene-1,3(2H)-dione, abbreviated as DVB-T-ID, was synthesized using 1,3-indanedione acceptor and dimethoxy vinylbenzene donor units, connected through a thiophene π-spacer. The presence of a dimethoxy vinylbenzene unit and π-spacer in DVB-T-ID significantly improved the absorption behavior by displaying maximum absorbance at ~515 nm, and the reasonable band gap was estimated as ~2.06 eV. The electronic properties revealed that DVB-T-ID SOMs exhibited promising HOMO (−5.32 eV) and LUMO (−3.26 eV). The synthesized DVB-T-ID SOM was utilized as donor material for fabricating solution-processed bulk heterojunction organic solar cells (BHJ-OSCs) and showed a reasonable power conversion efficiency (PCE) of ~3.1% with DVB-T-ID:PC61BM (1:2, w/w) active layer. The outcome of this work clearly reflects that synthesized DVB-T-ID based on 1,3-indanedione units is a promising absorber (donor) material for BHJ-OSCs.

An organic nanocomposites, based on a conjugated polymer (MEH-PPV) as electron donor material and carbon nanopearls (CNPs) as electron acceptor material, have been elaborated and optoelectronically studied. The effect of CNPs concentration on the electric and photoelectric properties in these blends has been investigated. Dielectric measurements demonstrate that the blend conductivity displays a dramatic increase, reaching 0.6 S/m for a CNPs concentration about 1 wt.%. The elaborated organic nanocomposites were used as photoactive materials in organic solar cells.
