Hybrid and Dye‐Sensitized Solar Cells

Solar cells based on organic-inorganic hybrid materials that are of interest for photovoltaic (PV) applications include: colloidal quantum dot solar cells; silicon-organic hybrid solar cells; and dye-sensitized solar cell (DSC). This chapter reviews the current status of hybrid and dye-sensitized solar cell performance. It summarizes a notable prior work and background for each solar cell technology and focuses on the upper limit of the achievable open-circuit voltage (Voc). One of the many challenges of hybrid materials-based PV technologies is the short-term as well as the long-term stability. Recently PV devices based on silicon (Si)/organic heterojunction have been actively studied as potential candidates for high-efficiency, low-cost Si solar cell technology. Based on abundant materials and scalable coating technologies, these emerging PV technologies show the potential for low cost, lightweight, and flexible solar power generation on a large scale.
