Novel methods for the texturing of photovoltaic cells is described, wherein texturing minimizes reflectance losses and hence increases solar cell efficiency. In one aspect, a microstamp with the mirror inverse of the optimum surface structure is described. The photovoltaic cell substrate to be etched and the microstamp are immersed in a bath and pressed together to yield the optimum surface structure. In another aspect, micro and nanoscale structures are introduced to the surface of a photovoltaic cell by wet etching and depositing nanoparticles or introducing metal induced pitting to a substrate surface. In still another aspect, remote plasma source (RPS) or reactive ion etching (RIE), is used to etch nanoscale features into a silicon-containing substrate.
