A Chinese research team has built an all-perovskite tandem solar cell with a 19.6%-efficient wide bandgap top cell relying on a 2D/3D heterostructure and narrow bandgap bottom cell with a 21.3% ...

and was initially motivated by the desire to create fibres that guided by means of a photonic bandgap effect. The first successful PCF, however, guided because of an effective refractive index ...

We are also interested in functional integration of photonic devices with microfluidic, MEMS, photopolymer, and 2D materials to broaden the scope of chip-scale sensing and imaging devices.
