Organic-inorganic hybrid perovskites are viewed as a cost-effective alternative for photovoltaic devices, among other applications. Solution and low-temperature processin[...]

Random anti-reflection structured surfaces (rARSS) have been reported to improve transmittance of optical-grade fused silica planar substrates to values greater than 99%.[...]

Understanding exciton diffusion is a crucial step in the engineering and fabrication of organic photovoltaic (OPV) devices. We studied a variety of organic dyes in our re[...]

Random anti-reflection surface structures (rARSS) are non-periodic, densely packed, sub-wavelength structures, fabricated on an optical surface. Light incident to such a [...]
