For the last decade, perovskite solar cells have been in rapid growth, highlighted as a representative next-generation solar cell. Although SnO2 is suitable as the electron-transporting material of perovskite solar cells, there also have been some obstacles in the formation of uniform and thin layers of SnO2 on the uneven FTO substrate. In this work, we
Since the pioneering work of Grätzel and O''Regan in 1991, dye-sensitized solar cells (DSSCs) have attracted a lot of interest, because of their potential low-cost, simple assemble technology and good efficiency comparable to those of amorphous silicon cells [1].Typical DSSC consists of three major compartments: a mesoporous nanocrystalline TiO 2 film sensitized by

Hydrogel actually is a frame to contain the phase change material for applications, provides the adhesive and reusable property.
A series of novel gel polymer electrolytes (GPEs) was developed for quasi-solid-state dye-sensitized solar cells (DSSCs), to enhance their performance via mixed counterion effect.
