Development of Organic Dye Sensitized Solar Cell Incorporated with TiO₂ Nanostructures with Low Conversion Efficiency for Exploring Solar Energy Concepts

摘要

We developed an organic dye sensitized solar cell with TiO_(2 )nanostructures integrated into the photoanode. The sensitizer in this research paper was extracted from flame tree flowers (delonix regia ) and pawpaw (carica papaya ) leaves respectively. The flame flower was separated from its stalk. Each of the samples was crushed separately via the use of a porcelain mortar and pestle. The samples, each, was filtered and stored in test tubes. The dye is chemically connected to a porous layer of a wide band-gap semiconductor. The DSSC employing the nanocrystalline TiO_(2 )as photoanode shows a short circuit current density of 0.01849 mA/cm~(2), open circuit voltage of 0.525 V, fill factor of 0.520 and a power conversion efficiency of about 0.0051%.
