- Abstract
- We have fabricated two types of photovoltaic cells using CuPc/C-60 layer, and studied photovoltaic effects of these devices using xenon light source. One type of device is ITO/CuPc/C-60/BCP/Al and the other is ITO/PEDOT:PSS/CuPc/ C-60/BCP/Al. The PEDOT:PSS layer was made by spin coating, and the other organic layers were made by thermal vapor deposition. By measuring the currrent-voltage characteristics under an illumination intensity of light in the range of 10 similar to 400-mW/cm(2), we have obtained open-circuit voltage V-OC short-circuit current density fill factor and efficiency of the device. As the light intensity increases, the increases as well in the both devices. The V-OC remains to be constant 0.31 V in the device without PEDOT:PSS layer irrespective of the light intensities. However, there is a little variation of V-OC in device with PEDOT:PSS layer depending on the light intensity.
