Aqueous dispersions of colloidal poly(3-hexylthiophene) gel particles with high internal porosity

► Gel particle dispersions made from P3HT organogels for organic solar cells. ► Size and porosity of particles were dependent on bulk organogel concentration. ► Dispersions found to retain the electronic and optical signatures of parent organogels. ► Organic solar cells produced by spray-coating dispersions with soluble fullerene.
