Very High Efficiency Photovoltaic Cells Based on Fully Organic Multiple Quantum Wells: Final Report

NREL

Research output: NLR › Subcontract Report

Abstract

The principal project objective is to demonstrate relatively high solar conversion efficiency using extremely low-cost, thin-film technology based on crystalline organic multiple quantum well (MQW) photovoltaic cells. We base our work on recent observations both in our laboratory and elsewhere that have indicated the quantum efficiency of organic photoconductors based on vacuum-deposited thinfilms can be increased by at least two orders of magnitude (to at least 10%) if the organic films are grown in a highly ordered manner, and if organic multiple quantum wells are used in the absorption region. Thus, we are investigating the physical origin of this phenomenon, and we are growing thin-film MQW cells that demonstrate relatively high quantum efficiencies to determine the practicalityof crystalline organic thin-film cells for solar power applications. The investigations are based on a unique, ultrahigh-vacuum organic molecular beam deposition system in our laboratory.
