Organic Inorganic Hybrid Hole Transport Layer for Light Management in Inverted Organic Photovoltaic

A design to enhance the photocurrent density in an inverted bulk heterojunction organic solar cell is explored. Aluminum nanoparticles dispersed in the hole transport layer at the rear end of the device structure are observed to enhance the device performance through multiple effects including enhanced absorption and better charge collection. Modeling and simulations are used to understand the mechanisms of optical transport that underlie the enhancements which are experimentally observed.
