Dye-sensitized solar cells: Fundamentals, recent progress, and Optoelectrical properties improvement strategies

Interfacial Mass Diagnostics: Quantitative Perspective on Construction and Mechanism Understanding of Dye‐Sensitized, Perovskite and Quantum Dots Solar Cells

“…[1] The DSSCs is essentially a multiphase photoelectrochemical system, which has a "sandwich" structure mainly composed of conductive glass, nano-porous TiO 2 film, dye, electrolyte and platinum counter electrode. [2] Among these components, the TiO 2 film, which adsorbs the dye, is the core component of cells to achieve photoelectric conversion, and important energy conversion processes occur here. Later, quantum dot-sensitized solar cells (QDSSCs) were formed by using inorganic nanocrystalline semiconductor quantum dots (QDs) with a narrow band gap instead of dye molecules.…”

“…During photoelectric conversion, various chemical reactions and electron transport processes occur inside the device, involving multidisciplinary cross-cutting fields such as photochemistry, photophysics, electrochemistry, catalytic chemistry and interface chemistry. [2] These cells are not only an excellent photovoltaic device, but also a representative of a complex photo-electric physicochemical system. [5] Up to now, a series of problems such as the photoelectric conversion mechanism, device stability and aging mechanism of DSSCs, QDSSCs and PSCs are still unclear.…”
