1. The Future of Thin Film Solar The Plastic Substrate

3. Organic Semiconductors Insoluble Soluble Liquid Crystalline

4. Organic Semiconductors Monomers Dyes Piments Polymers Potential Uses are Greater Flexible Lightweight Less impurities can form

5. Market Value of Thin Film in Solar Panels Prices of thin film solar panels are decreasing each year compared to their crystalline counterpart. Avg. price of thin film panels are around $1.40. Thin film panels are getting more efficient in converting light into energy. Thin film solar panel production is much cheaper than crystalline solar panels.

6. Solar Market Expansion “No. 1 solar energy country Germany will install 9.5GW worth of PV systems in 2011.” “The United States will install the third largest total of PV systems in 2011, at 1.9GW, up 79.3% from 1.1GW in 2010.”

7. Organic Semiconductors o- chloranil 2,4,7- trinitrofluorenone Tetracyanoquinodim -ethane (TCNQ)  Used in manufacture of dyes & pigments  Photoelectrically active ingredient of the coating mixture deposited on the photoconductor film on the exterior of the printing drum in 1979 IBM photocopiers & printers  Also used as fungicide against rice leaf blight  Electron acceptor used to prepare charge-transfer salts (electron transfer)

8. The Future Single element & organic semiconductor films are best suited for device manufacturing Chemically tailored materials Inexpensive technologies Research Improvement of stability of conjugate polymers Matching bandgap of organic materials with solar spectrum for higher conversion efficiency by using blended/composite polymers and suitable dyes
