英文摘要: Energy consumption plays a key role in human existence and global economics development. Solar cell or photovoltaics technology is one of the most efficient tools in replacing fossil fuels (nonrenewable source of energy), such as coal, natural gas, and oil. The project aims at solving Maxwell's equations and organic semiconductor equations (Poisson equation, current continuity equation, and drift-diffusion equation) self-consistently by using fast, efficient, and unified finite-difference framework. We will apply the multiphysics model to 2D/3D arbitrary-shaped complex plasmonic organic solar cells. We will also design new device configurations through deep physical understanding of the interplay between electrons and photons. The project will offer theoretical foundations and engineering supports for high-performance organic solar cells. Moreover, it will promote the technology revolution and market predominance for Chinese photovoltaics industry.
