【 摘 要 】

Today, solar cells have become one of the promising renewable energy alternatives to provide a clean and environmentally friendly. One of the solar cell technologies, which has been widely developed and studied intensively, is dye-sensitized solar cells (DSSC). DSSC optimization component is performed to produce a high conversion efficiency. One part of DSSC which plays an essential role in energy conversion is photoanode, and TiO2 nanocrystals have been proven to be high-efficiency DSSC photoanode components. The metal oxide TiO2 exhibits a high mesoporous surface area which can be used for dye absorption. The most widely developed organic material in DSSC is PANI. It is a conducting polymer that has a wide range of absorbance, porous morphology, excellent electrical properties, and ease of bond with metal ions. The PANI-TiO2 composite system forms a bilayer structure that is expected to improve the efficiency of DSSC conversion. So far, no comprehensive study of DSSC-based PANI/TiO2/FTO-Glass bilayer thin film structure as a photoanode component has been done. In this works, we report the effect of photoanode thickness represented by spin rotation on the optoelectronic properties is needed.
