Recent Progress in Colloidal Quantum Dot Solar Cells: Novel Strategies in Synthesis and Device Structure

콜로이드 양자점 태양전지의 최근 발전 동향: 양자점 합성과 소자 구조에서의 다양한 접근 방법

Colloidal quantum dot (CQD) solar cells have attracted great attention due to their cost-effectiveness and solution-processability, as well as their size-dependent optical and electrical properties. The power conversion efficiency of CQD solar cells has rapidly increased up to ~8.6%, which corresponds to the 3 - 4 fold improvement during the last 3 - 4 years. Up to now, there have been many pioneering results in CQD solar cells. Here, we review the recent progress of CQD solar cells including CQD synthesis strategy and device structure engineering.
