Efficient organic photovoltaic diodes based on doped pentacene

Article Abstract:

Efficiency enhancement by molecular doping in Schottky-type photovoltaic diodes based on pentacene, an organic semiconductor, is demonstrated. The dopant improves internal quantum efficiency by over five orders of magnitude, yielding external energy conversion efficiency up to 2.4% for a standard solar spectrum.
