Experimental demonstration of silicon inverse opal photonic crystals (PhCs) as a wave‐optics‐based back reflector for polycrystalline silicon solar cells is shown. Using a novel S 5 process, crack‐free three dimensional PhCs are fabricated, which are free‐standing and have good optical properties. An efficiency enhancement of 10% is measured for 1.5 μm‐thick commercial silicon solar cells, matching reasonably well with simulations.
