Increasing The Efficiency Of Organic Solar Cells Through Improving ZnO Conductivity

A power conversion efficiency (PCE) of over 13% has been accomplished for single-junction polymer solar cell (PSCs) through the preparation of novel donating materials and interfacial engineering (surface modification). The interfacial layer is essential for improving charge extraction to the electrodes, avoiding non-ohmic contact losses, suppressing recombination, and exaction quenching of the charge carrier at the interfaces. However, due to the relatively low charge mobility, most devices with high performance are made by very thin interlayers (2-10 nm). This is...
