Only ten micrometer thick crystalline silicon solar cells deliver a short-circuit current of 34.5 mA cm-2 and power conversion efficiency of 15.7%. Here, the record performance for a crystalline silicon solar cell of such thinness is enabled by an advanced light-trapping design incorporating a 2D inverted pyramid photonic crystal and a rear dielectric/reflector stack.
