On the 19th, the joint research team of Professor Park Hui-Joon of Hanyang University's Department of Organic and Nano Engineering and Professor Lee Jae-Jin of Ajou University announced that they have developed a 'tandem solar cell' by combining a flexible 'Gallium-arsenic (GsAs) compound' and a 'Perovskite semiconductor.'
They used the method that increases the conversion efficiency of electronic energy by using more diverse wavelength lights, laminating a semiconductor compound crystal that absorbs large wavelengths of light, over a thin film of Perovskite that absorbs short-wavelength light.
The research team succeeded in creating a thin film of Perovskite with high-efficiency, by using a method of low-temperature solution processing. The tandem battery that is made through putting the film over a gallium-arsenic compound is found to have 15% higher efficiency.
A possible increase in the price of the tandem solar battery has also been managed by using low-cost Perovskite, which has the function of increasing the photoconversion efficiency of the semiconductor compound.
Professor Park mentioned that "the newly developed tandem solar battery is very light and flexible, which makes it useful for automobiles, drones, wearable devices, as well as the energy source for IoT (Internet of Things) sensors."
The research has been conducted with the support of the Ministry of Science and ICT, the Ministry of Education, and the Fundamental Research Business by the National Research Foundation of Korea, and the result of the research was published on the cover paper of an international academic journal, 「Advanced Energy Materials」, on December 19th, 2019.
