Abstract
Anew material based on poly (hydroxyl-phenylene) has been prepared. Polymer doped with some metal chloride salts such as Fe, Co, or Cd was added to the material in order to obtain flexible films of the structure: Aℓ /Poly(1,2,3 trihydroxy-4,5 Phenylene)+ PSS doped M-chloride/ITO UV-Vis Spectra shows broadband absorption enhancement in the UV, visible and near infrared portion of solar energy. The current density-voltage (J-V) characteristics under forward bias were found to exhibit two regions. At low voltages the devices showed Schottky diode behavior. At higher regions the results showed ohmic conduction. Under reverse bias, the conduction processes were interpreted in terms of both the Pool- Frenkel and Schottky effects. The capacitance versus reverse bias voltage is linear which indicates the formation of Schottky junction, the built-in voltage and the charge concentration were also found to be influenced by the presence of the metal chloride salts. Under illumination, the J-V curves are used to estimate the solar cell parameters such as open-circuit voltage, short-circuit current, fill factor, and energy conversion efficiency.
