Characteristics of Cu/p-CuI/Rhodamine-C₁₈/CNT Solid State Photovoltaic Cell

A thin film solid state photovoltaic cell was prepared by depositing Rhodamine-C₁₈(R-C₁₈) on Cu/p-CuI photoelectrode and then, carbon nanotubes (CNT) were deposited on dye coated p-CuI before placing the ITO glass plate as upper electrode. R-C₁₈ dye was deposited by simple dipping technique on the p-CuI transparent layer. In this paper the diffuse reflectance spectra, photocurrent action spectra, I-V characteristics and stability curves were used to discuss the characteristics of solid state thin film solar cell. The maximum power conversion efficiencies reached without and with CNT layer were 0.5% and 1.5% respectively.
