We discuss the integration of quantum dashes (QDashes) into laser simulations using Crosslight Pics3D, outlining the approach for developing a model featuring asymmetrical active regions. The importance of including wetting layers to accurately represent carrier transport is investigated using results obtained for an InAs/InP QDash laser. While leakage current across the active region is unaffected […]

Enormous potential lies in waste-heat recycling for the world’s industrial sector. Portable solid-state modules are a universal low-maintenance method to recycle this waste-heat. One such technology, near-field thermophotovoltaics (NFTPV), relies on a heat source in extreme proximity (<200 nm) to a photovoltaic cell, which then generates electricity. We developed an optoelectronic model where electron-hole pair […]

We investigate the impact of surface texturing on current loss as a function of depth and wavelength in high efficiency bifacial silicon heterojunction solar cells operating at their maximum power output. We couple 3D ray tracing with TMM thin-film boundary conditions for optical simulations and solve Poisson’s drift-diffusion equations to calculate carrier recombination under both […]
