Photovoltaic Cells Involving the Nonconjugated Conductive Polymer, Iodine-Doped Poly(β-pinene)

Novel photovoltaic cells involving a nonconjugated conductive polymer have been fabricated using titanium dioxide/doped poly (beta-pinene)/carbon on ITO glass-substrates. Photocurrents and photo-voltages for different intensities of light (emission at 300-700 nm) have been measured. Use of iodine-doped nonconjugated conductive polymer (poly(beta-pinene)) film has led to significant enhancement of photocurrent compared to previous reports involving undoped polymer in a different device-structure. A photocurrent density of about 0.03 mA/cm(2) and a photo-voltage of 0.65 V have been measured for a light intensity of similar to 5 mW/cm(2). These cells being the first generation of its kind the results are promising for applications.
