Very High Performance Organic Photonic Devices
Abstract
The objective was to demonstrate very high efficiency, low cost organic solar cells on flexible substrates based on vapor-deposited thin film organic semiconductors. Our goal is to obtain solar power conversion efficiencies of >10% -- a value without precedent in over 30 years of science and engineering targeted at achieving practical organic solar energy conversion devices. A further objective is to demonstrate an electrically pumped organic thin film laser, again based on vapor-deposited molecular organic materials. The motivation for this investigation is the temperature independent wavelength and threshold characteristics of organic lasers. We will pursue two very promising and innovative approaches: employing high Q cavities where electrically pumped polaritons are generated, and the use of high intensity OLEDs to pump a low threshold light emitting film positioned in an integrated optical cavity.
