Schematic of the (a) spectrum-splitting system and (b) wedge-shaped photonic crystal; (c) absorptance of the GM-PV cell in the wedge-shaped microcavity (inset: thickness variation of the defect layer with varying position coordinates); (d) absorptance of the GM-PV cell in the split wedge-shaped microcavity (inset: shoulder-to-shoulder wedge-shaped microcavity).
