The periodic nanoisland structure on front surface of thin film silicon with an aluminum back-reflector. (a) SEM image of periodically arranged polystyrene spheres in a hexagonal lattice, (b) the remaining nanoislands after titanium dioxide (TiO2) deposition and nanosphere lift-off, and (c) the calculated short-circuit current density Jsc (mA/cm2) for a 2-μm-thick thin film crystalline Si as a function of structural parameters.
