Abstract

NASA future exploration missions and space electronic equipment require improvements in solar cell efficiency and radiation hardness. Novel nano-engineered materials and quantum-dot (QD) based photovoltaic devices promise to deliver more efficient, lightweight, radiation hardened solar cells and arrays, which will be of high value for the long term space missions. We describe the multiscale approach to the development of Technology Computer Aided Design (TCAD) simulation software tools for QD-based semiconductor devices, which is based on the drift --- diffusion and hydrodynamic models, combined with the quantum-mechanical models for the QD solar cells.
