Room-temperature fabrication of multi-deformable perovskite solar cells made in a three-dimensional gel framework

Abstract

Ultraflexible perovskite solar cells are made by absorbing solar cell materials into 3D gel framework, yielding enhanced photovoltaic performances under deformations.

Dual Interfacial Modification Engineering for Highly Efficient and Stable Perovskite Solar Cells

“…[ 23–25 ] Meanwhile, polyethylene glycol (PEG) is widely used to prepare the perovskite film, which can promote to form a thin hydrophobic layer in perovskite films. [ 24,26–30 ] However, most researchers used PEG in the precursor solutions of perovskite, which hinder the carrier transport through perovskite films, due to the poor conductivity of PEG. Moreover, there are quite few investigations combining the solvent annealing and PEG methods to improve the quality of perovskite film.…”

Metal/TiO2 hierarchical nanocomposite arrays for the remarkable enhancement of photocatalytic activity

“…Pioneering works in the early 1970s revealed that hydrogen can be produced by photocatalytic water splitting over a TiO 2 semiconductor under UV irradiation, leading to the broad investigation of nanosized TiO 2 for in vivo imaging, cancer therapy, protein separation/purication, dye-sensitized solar cells, perovskite solar cells and bactericides. [1][2][3][4][5][6][7][8][9][10][11] Utilizing sustainable solar energy is of paramount importance in developing photocatalysts for wastewater treatment. In fact, as a kind of typical azo dyestuff, methyl orange (MO) is one of the main substances in the wastewater industry, and its removal has drawn widespread attention.…”
