The ever-growing world population leads to an increase in energy demand. Nowadays, we heavily rely on non-renewable energy sources to fulfill the energy demand. This dependence on non-renewable energy sources must be reduced due to diminishing supplies and adverse environmental effects of its emission. One of the ways to solve this problem is by using alternative energy sources. The most promising alternative energy source is solar energy. As a country that lies on the equator, Indonesia receives constant sunlight exposure throughout the year which means high solar energy potential. Solar energy can be directly used to produce electricity using photovoltaic cells. One of the newest generation of photovoltaic cells is the dye sensitized solar cell (DSSC), with its ability to utilize diffused light. The goal of this study is to make a DSSC module and test its performance. This study aims to determine the characteristics and reproducibility of the TCO glass for the DSSC module, as well as the effect of the number of cells in a module with the same total active area to the performance of the DSSC module. The conductive glass was fabricated using spray pyrolysis method. Characterization of the conductive glass was performed by using UV-vis spectrophotometer and four-point probe to test its transparance and resistance respectively. Both electrodes were deposited using doctor blade method. Characterizations of the DSSC module were performed by IVP curve measurement, fill factor and light conversion efficiency calculation, as well as electrochemical impedance spectroscopy. The number of cells in the DSSC module was varied to 1, 2, 3, and 4 cells with the total active area of 60 cm2. The results of the conductive glass for the DSSC module showed T, R, and FOM in the range of 77,45-85,32%; 5,85-17,82 ?/sq; and (9,10-13,21) × 10-3 ?-1 respectively, with a confidence level of 95%. Reproducibility test for the conductive glass results were relatively consistent, with T, R, and FOM standard deviation of 2,01%; 3,05 ?/sq; and 1,05 × 10-3 ?-1 respectively. The two-celled DSSC module was fabricated with an efficiency of 6,68 × 10-4 %.
