Cosensitization strategies for dye–sensitized solar cells

Abstract

This chapter begins by listing the advantages of dye-sensitized solar cells (DSSCs). It also summarizes their five major components: conductive and transparent glasses; nanocrystalline semiconductor film; dye sensitizer; redox couple; and counterelectrode. Among these, the sensitizer is one of the key components in achieving high efficiency. Many type of metal complexes and metal-free organic dyes can be used in DSSC fabrication. However, the major drawback of using a single sensitizer is failure to harness photons either from visible or near infrared (NIR) region. In this regard, cosensitization is found to be alternative method. The chapter focuses on the relationship between a structural ..
