Abstract: Carbon nanotubes hold great potential for use in photovoltaic cells. Carbon molecules are long thin cylinders of carbon. Nanotubes have a broad range of electronics thermal and structural properties. They are molecules that can be manipulated chemically and physically in very useful ways. They open an incredible range of applications in material science, electronics, chemical processing, energy management and many other fields. Nanotubes are classified as single walled nanotubes and multi walled nanotubes. A SWCNT are ideal as thin film photovoltaic because they absorb light across wide range of wavelengths from visible to near infrared and possess charge carriers that move quickly. Organic photovoltaic devices are fabricated from thin films of organic semiconductors such as polymers and small molecule compounds and are typically on the order of 100 nm thick. Polymer based OPVs can be made using coating process such as spin coating or inkjet printing. A promising alternative to silicon conventional solar cells.
