In the past few years, squaraine dyes have received increasing attention as a sensitizer for application in dye-sensitized solar cells. This class of dyes not only leaves open a good opportunity to afford conventional high performance dyes but also holds great promise for applications in transparent solar cells due to its low absorption intensity in the eye-sensitive region. This review provides a summary of the developments on squaraine dyes in the field of dye-sensitized solar cells and the opportunities used to improve their overall energy conversion efficiency. In particular, the main factors responsible for the low values of open-circuit voltage, short-circuit photocurrent and fill factor are discussed in detail. Future directions in research and development of near-infrared (NIR) organic materials and their applications are proposed from a personal perspective.
在过去的几年中，方酸染料作为敏化剂在染料敏化太阳能电池中的应用受到了越来越多的关注。这类染料不仅为提供传统的高性能染料提供了良好的机会，而且由于其在眼睛敏感区域的吸收强度低，在透明太阳能电池中的应用也具有很大的潜力。本综述提供了染料敏化太阳能电池领域中方酸染料的发展情况以及提高其整体能量转换效率的机会的总结。特别是，详细讨论了导致开路电压、短路光电流和填充因子值较低的主要因素。从个人角度出发，提出了近红外（NIR）有机材料及其应用的未来研究和发展方向。
