About :
As global warming becomes more serious, voices are growing louder calling for the use of renewable energy. In particular, solar cells, which were developed through human efforts to use solar energy, a great natural product, are currently being used in various fields. However, the currently commercialized 'silicon solar cells' are expensive and have low space efficiency, so research on 'perovskite solar cells', one of the next-generation solar cells that can overcome these shortcomings, is receiving keen attention from the academic community. Perovskite solar cells are solar cells that use a material called perovskite as a photoactive layer. Unlike silicon solar cells, which are greatly affected by the angle of incidence and are limited in their installation location, perovskite solar cells can be installed on building exteriors or vehicle sunroofs. Perovskite solar cells are thin, light, and flexible, and can be made inexpensively using a solution process. Dr. Seok Sang-il's team, known as an authority on domestic perovskite solar cells, has devised the world's first method to make the surface of perovskite solar cells uniform. Thanks to that, the paper published in 2014 is said to have become the Bible of perovskite solar cell synthesis. Since then, the solar cell developed by Dr. Seok's research team has surpassed 20%, which was called the 'magic efficiency', for the first time, and has broken the world's highest efficiency certified by the US New and Renewable Energy Laboratory several times. Recently, they are said to be spurring research on large-area perovskite solar cells so that they can be commercialized. The sun that burns itself hot and lights up every corner of the earth. That's why we are in awe of people with unquenchable passion. Let's take a look at the story of Dr. Seok Sang-il, who is devoted to research with burning passion, although he started later than others. #Perovskite #Solar cell #Solar power #Global warming #Renewable energy #Solar energy #Eco-friendly energy #Next-generation solar cell #Eco-friendly #Energy chemistry #Sun [Copyright (c) YTN science Unauthorized reproduction, redistribution, and use of AI data prohibited]
