フタロシアニン粒子分散型太陽電池のNO_2ガス吸着効果 N0_2 Gas Adsorption Influence on Phthalocyanine Binder Layer Solar Cells
Photovoltaic performance of a Schottky barrier phthalocyanine binder layer solar cell was studied, together with NO<sub>2</sub> adsorption influence on performance. A phthalocyanine layer was prepared on an indium tin oxide (ITO) glass substrate by spin coating, and a semitransparent aluminum electrode was vacuum-deposited on the phthalocyanine layer. Copper phthalocyanine (CuPc) was used as a photoactive particulate semiconductor, polyvinylidene fluoride (PVdF) a polymer binder and N, N-dimethylacetamide (N, N-DMA) as a solvent. The CuPc solar cell showed good rectifying characteristics in the dark and photovoltaic effects under light illumination. The photovoltaic performance of the solar cell was improved by NO<sub>2</sub> adsorption onto the CuPc layer, attributable to increased carrier (hole) lifetime caused by the NO<sub>2</sub> adsorption capturing electrons. However, NO<sub>2</sub> adsorption promotes oxidation of the aluminum electrode and deteriorates the Schottky barrier between the CuPc layer and aluminum electrode, deteriorating the solar cell's photovoltaic performance.
