Description
Summary:High intrinsic carrier mobility and excellent transparency at visible wavelengths make stannic oxide (SnO2) a material of interest for a variety of optoelectronic applications. Here, we demonstrate a solvothermal route to stabilize gelled dispersions of tin oxide nanoparticles with diameters in the range of 2–4 nm. Small particle dimensions ultimately allow for the deposition of smooth thin films with all of the useful properties that can be expected from this material system. The structural and morphological properties of the deposited films are investigated, and they are demonstrated as an electron collection layer in polymer-based organic photovoltaic cells with promising power conversion efficiencies.
