Solar cells are thought about to be an eco-friendly resource of power generation that can successfully minimize the effect of air pollution on the atmosphere. In particular, perovskite quantum dot solar cells have attracted considerable attention from the academia due to their reduced production expense as well as their ability to be related to flexible materials, which standard silicon solar cells lack.

Last summer season, cities of Korea including Seoul were hit by an unmatched heavy rainfall, which swamped various locations. In a similar way, torrential downpours engulfed concerning one-third of Pakistan, resulting in prevalent flooding. New York City State was not spared as it experienced heavy snow storms in December of last year, with snowfall of more than one meter.

POSTECH study group included Prof. Taiho Park as well as Junwoo Lee, a pupil in joint MS-PhD program created Alkoxy-PTEG, opening transportation polymers that could be liquified in pepper mint oil, by using ethylene glycol side chains when they generated high effectiveness perovskite solar cells. Additionally, they verified that this polymer caught dripping lead in the aged perovskite solar cells.
