The STAR Lab (Solar cell Trailblazer for Advanced Research Laboratory) is a laboratory that researches next-generation solar cells. One of the most popular renewable energy sources is solar cells. Solar cells can be divided into first-generation, second-generation, and third-generation solar cells. The first generation is silicon-based solar cell, and the second generation is a thin film solar cell. Third-generation solar cells include organic photovoltaic, dye-sensitized solar cells (DSSC), quantum dot solar cells (QDs), and perovskite solar cells (PSCs). Among them, PSCs have the shortest research history, but the world's highest efficiency is exceeding 25.7%, which is comparable to that of silicon solar cells. In order to realize the high efficiency of the next-generation solar cell, it is necessary to select an optimized photo absorption layer, to manufacture a thin film that can efficiently move the electrons and holes formed by light, and to study to manufacture whole process. Our laboratory is to realize the world's best efficiency by utilizing various photo absorption materials and characteristics of next-generation solar cells. In addition, research that can manufacture small-area source technology in a large area is also researched. It is an important research goal not only to manufacture next-generation solar cells, but also to improve the efficiency of next-generation solar cells through analysis of characteristics and analysis related to solar cells.
