LD06–Effect of Wetting Layers on Quantum Dash Laser Operation in Crosslight PICS3D

Schaefer S., Obhi R. J. K., Valdivia C. E., Hinzer K.

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 […]

SC03–Modeling Efficiency of InAs-Based Near-Field Thermophotovoltaic Devices

Forcade G., Valdivia C. E., Lu S., Molesky S., Rodriguez A., Krich J., St-Gelais R., Hinzer K.

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 […]

SC04–Impact of surface texture on bifacial silicon heterojunction solar cell carrier loss

Tonita E. M., Valdivia C. E., Hinzer K.

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 […]
