Professor Kim Eun-kyu of the Department of Physics is July’s Researcher of the Month for his active role in spreading knowledge in the field of physics. In his paper, “Iodide management in formamidinium-lead-halide-based perovskite layers for efficient solar cells”, Kim explains how he has created the ‘perovskite solar battery’ with the best efficiency in the world. Perovskite batteries have high efficiency and low production cost which is how it is gaining interest for the next generation solar energy source.
 
Kim is explaining about the perovskite solar battery.

Perovskite is material created out of anion, cation, and halide and is used inside the solar battery to create electricity. Kim has carried out his study along with Ulsan National Institute of Science Technology (UNIST) and Korea Research Institute of Chemical Technology (KRICT) and the paper has been introduced in the world renowned academic journal, Science. The research has been carried out through the support of Ministry of Science, ICT and Future Planning.
 
The key theme of the research has been that through the control of halide, efficiency was to be raised from 20.0% to 22.1%. Currently, solar batteries are created with silicon materials but with the newly developed technology, new solar batteries could produce the highest efficiency with half the cost. Not only could it be used in the solar batteries, but they could also be used to produce new and renewable energy in the future with further integration of different technologies.

Kim has started this study since all types of batteries should implement high level of efficiency. With high efficiency follows the lower production cost which was why this was important for the commercialization of the solar battery field. Kim and his research team are the best in the field currently showing the highest level of efficiency and still working for better technology. Although the technology itself has been developed to produce the most efficient solar batteries, mass production and commercialization problem is yet to be solved.
 
Kim and his team are currently working on the perovskite battery to further test its safety and to control the halide. Although Kim and his research team have already reached their goal of creating the efficient battery and printing their paper on Science, further studies will be carried out to make the lives more convenient for people.  

 
Kim wishes to develop a more efficient solar battery in the future.
