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.
