Description:	The solar cell efficiency is growing from time to time to serve the solar energy needs. One of the methods to improve the efficiency is by improving the metal contact of the single junction silicon solar cell. The objectives of the research is to optimise the screen printing process and also co-firing temperature in order to produce high efficiency solar cell. The enhancement of a solar cell involved in the whole process of the cell development. Only Si solar cells will be discussed and optimising this kind of cell will focus on the back end process, which is metallization process that involve after the texturing process. Simulation was first done to evaluate the effect of the contact parameters such as the emitter resistance, base resistance and the area of exposed cell using PC1D. Not all parameters in simulation process can be comprehended in laboratory experiment and vice versa. The effect of emitter and base resistance were verified with thermal treatment test, while the cell area was verified with mesh type test. The paste type test was not comprehended in simulation process due to no simulation parameter can be evaluated. The experimental process involved would be metal contact screen printing and metal paste co-firing. The metal contacts were form using Al solder paste for back contact and Ag solder paste for front contact using screen printing process. To complete the metallization, the printed cells were then fired in the conveyer furnace, the process called Rapid Thermal Annealing. The characteristic of the cells were then tested. By optimising the metallisation process, the result found that the efficiency of the solar cell managed to be increased to 18.8%, 1.68% better than compared than the previous research. From this study, the method can be only applied not only to single crystalline silicon solar cell but also for multicrystalline silicon solar cell with single junction.,Certification of Master's/Doctoral Thesis" is not available
