Despite unprecedented development, PSCs based on operationally instable and extremely expensive organic hole-transporting materials (HTMs) such as N 2, N 2', N 2', N 7, N 7, N 7', N 7'-octakis(4-methoxyphenyl)-9, 9'-spirobi[9H-fluorene]-2, 2', 7, 7'-tetramine or poly[bis(4-phenyl)(2, 4, 6-trimethylphenyl)amine] are far from commercialization. There is an urge to develop new sustainable materials to combat these issues associated with organic-based HTMs. This chapter focuses on the significance of metal oxide-based inorganic functional materials as HTMs in different PSC architectures. The first section of the chapter presents the basics of PSC technology, including working principles, device structures, components, and challenging issues. The following section introduces sustainable hole conductors as well as an outline of the current routes to enhance long-term operational stability and reduce material cost using innovative approaches. The prerequisites of a novel HTM and compatibility with neighboring layers are also briefly discussed. In the last section, highly promising metal oxide-based inorganic HTMs and current progress are highlighted comprehensively to illustrate the importance of inorganic materials in terms of the state-of-the-art of PSCs. Overall, this chapter provides a roadmap of the current demands and future research directions to address the main critical concerns of PSCs that must be tackled to mitigate the major barriers on the pathway to upscaling applications. © 2021 Elsevier Inc.

This chapter focuses on the significance of MO-NPs as an electron transport layer (ETL) in dye-sensitized solar cells (DSSCs). The first section of this chapter presents readers with an introduction to DSSC technology and its working principles. The second section introduces feasible metal oxide-based ETL materials and an outline of current routes to boosting the device’s performance using innovative approaches through the molecular engineering aspect of ETL materials. In the last section, highly promising titanium dioxide (TiO2)-based ETL and its ability to be modified are highlighted in detail to illustrate the importance of TiO2 in terms of the state of the art of DSSCs. © 2018 Elsevier Inc.
