Organic Photovoltaic (OPV) Devices Fabricated Using Non-Toxic, Water-based Nanoparticle Dispersions

Primary Inventors: 
Description: 

This invention provides organic photovoltaic devices fabricated using an environmentally friendly fabrication process.  To fabircate a solar cell that will power a smart phone using conventional fabrication processes would require 150 mililiter of toxic organic solvents such as chlorobenzene or xylene. The new fabrication process of this invention uses waster-based nanparticle dispersions of active layer materials, and improves device power conversion efficiency over other aqueous-dispersion-based processes by optimizing the domain size and structure of the active layer and other device elements.

Applications: 

OPV devices or organic solar cells fabricated using an environmentally friendly process Lightweight, Flexible and portable organic solar chargers for mobile phones, smart phones, tablets, integrated audio-visual devices, low-pwer personal electronic devices for sensing and medical diagnostics, etc.   

Advantages: 

Environmentally safe, Scalable, Amenable to Roll-to-Roll processing
