Engineering magnetic nanomaterials for enhanced organic solar cell performance: A review

Abstract

Organic solar cells are a class of photovoltaic technologies that have complemented the currently available inorganic silicon-based solar cells. The increased energy consumption requirements from industries and households have led to an increased need to improve the current conversion efficiency of photovoltaic technology. The incorporation of a magnetic field into the active layer of organic solar cells has been established for improved conversion efficiency. The current review outlines the recent progress and strategies that have been employed in engineering the transport properties of magnetic-based organic solar ce. The main contributing factors to the enhanced performance of the reported organic solar cells are attributed to the rate increase of the intersystem crossing of singlet to the triplet states. The review discusses the current challenges hampering the commercialization of the technology and the prospect of magnetic field-based organic PV technology.
