Si Inverse Opal Solar Cell work highlighted in Nature Photonics

Researchers from Japan and Canada have produced the first ever solar cell containing an integrated 3D silicon photonic crystal. The cell is based on an intrinsic silicon layer with an inverse opal structure — a 3D photonic crystal with an omnidirectional photonic bandgap — sandwiched between n- and p-doped crystalline silicon layers. The cell traps light and prolongs the lifetime of charge carriers, thus reducing leakage current and improving the cell’s fill factor.
