Organic solar cells (OSCs) containing an active layer consisting of a nanostructured blend of a conjugated polymer like poly(3-hexylthiophene) (P3HT) and an electron acceptor have the potential of competing against silicon-based photovoltaic panels.

Carbon Nanopearls

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.

A small organic moleculeCSORG5developed as non fullerene acceptor for BHJ solar cells. The device based on P3HT : CSORG5(1 : 1) spin coated from DIO/THF showed high PCE 2.80% compared to spin coated from THF. The PCE has been further increased to 4.16%, when the TiO2film was inserted between the active layer and Al electrode.
