Research status on fabrication technologies of polymer solar cells

聚合物太阳能电池具有质量轻、柔性、可大面积制备等优点,成为当前能源领域的研究热点。光活性层是聚合物太阳能电池的核心部件,扮演着将光子转换为电荷的角色。因此,它的制备技术与工艺过程是影响光电转换性能的一个重要因素。本文从光活性层及与其相关的功能层的制备角度出发,综述了旋涂、喷涂、卷对卷、喷墨打印四种技术在聚合物太阳能电池领域的研究进展,最后对这四种技术在有机光伏领域的发展进行了展望。

Polymer solar cells （PSC） became the current research focus in the energy field, owing to their outstanding advantages in lightweight, flexible and large-area of fabrication. Photoactive layer was the core component of PSC, which played the role of converting photon into charge. Therefore, its fabrication technology and process were an important factor to affect its performance. In this paper, four fabrication technologies, including spin coating, spray coating, roll-to-roll and inkjet printing are reviewed based on fabrication of photoactive layer and related functional layer. In addition, the application prospect and tendency of these technologies in the field of organic photovoltaic are discussed.
