Paper Abstract

Organically modified silica (ORMOSIL)-coated dye-sensitized solar cells (DSSCs) with improved energy conversion efficiency are demonstrated. ORMOSIL-coated DSSC surfaces exhibit omnidirectional low reflectivity over a broad range of wavelengths (400–800 nm). The short-circuit current density (JSC) is enhanced up to 23% at normal incidence (θ=0  deg) as a result of ORMOSIL coating. In addition, JSC enhancement is even higher at larger angles of incidence; 84% enhancement was observed at θ=30  deg. Moreover, ORMOSIL coating is superhydrophobic with a contact angle of 155 deg.
