The rapid evolution of efficiency and long-term stability in perovskite solar cells for commercialization |
| 초록 |
Perovskite solar cells (PSCs) in which organometal halides act as photoabsorption materials have achieved power conversion efficiency (PCE) of approximately 23 % by improving perovskite materials and fabrication process. Nowadays the substantial progress have been achieved to commercialize PSCs based on such as high PCE with developing large-area compatible process and long-term stable devices. In this presentation, I will briefly review the key technologies in KRICT for obtaining high PCE of PSCs. Firstly, the process for coating a high-quality perovskite layer will be introduced, which includes solvent engineering, composition engineering, and defects control. Then, recent progress for high-efficient and long-term stable PSCs will be presented, which is focused on new electron transport materials (ETMs) and hole transport materials (HTMs). PSCs with tin-based oxides as ETMs exhibit superior long-term stability against illumination including UV, and copper phthalocyanine is one of the most thermally stable HTMs. |
