摘要： Dye-Sensitized Solar Cell (DSSC) has the cost of fabrication is relatively cheap, easy to produce, work on the area of the visible light and environmentally friendly. The shortage of DSSC, namely the efficiency is still low compared with solar cells of silicon. In this study, have been successfully fabricated DSSC with clathrin protein deposited. The method used in this research is to deposit clathrin protein in porous TiO2 semiconductors with a concentration of 0%, 25%, 50%, and 75%. Tests carried out on the DSSC that has been made current testing electricity using a solar simulator to determine the changes in electrical current that occur in DSSC. The conclusion from this research is that with increasing concentration of the addition of the clathrin protein in the DSSC leads to an increase in the electric current generated by DSSC. From the results of testing using a solar simulator obtained the value of electric current is the highest, namely 5.247 mA with the addition of the concentration of the clathrin protein by 75%.
