介绍了纳米偶极子光伏器件的发展历史和现状,阐述了在这种新型光伏器件中观察到的非经典行为。即开路电压可受外电场控制而改变的现象,并将之与铁电光伏器件、压电光电子器件、含有光诱导偶极子场的有机光伏器件和量子点光伏器件等进行比较,提出了偶极子场半导体器件的概念。期望从更广义的范围涵盖结场型器件和非结场型偶极子器件,为促进光伏发电领域更多的创新提供思路。
It focuses on discussion of the developing history and current status of nano-dipole photovoltaic(PV)devices, as well as presenting non-classical behavior of this kind of device, which is the tunable open circuit voltage under external bias field. Nano-dipole PV device is also compared to ferroelectric photovoltaic device, piezo-phototronic device, light induced dipole field and so on. The concept of dipole-semiconductor device is proposed which intends to cover the junctional devices and non-junctional devices by a more generalized scope and to provide new thoughts to stimulate innovation in the photovoltaic field.
