Photochromic organic solar cells based on diarylethenes

Abstract

A diarylethene dye that reversibly changes color upon illumination is used in a switchable photochromic organic solar cell.

Production of photochromic nanocomposite film via spray‐coating of rare‐earth strontium aluminate for anti‐counterfeit applications

“…Thus, the optical character of the photochromic organic materials is inhibited. [ 46 ] On the contrary, photo‐responsive inorganic materials do not undergo steric effects as their photochromic exchange is not correlated to structural changes as in organic molecular switches. [ 47 ] Furthermore, the long‐lasting exposure of photochromic organic molecular switches to UV light promotes their decomposition to result in decreasing their photochromic activity together with lower photostability.…”

Photochromic spiro-indoline naphthoxazines and naphthopyrans in dye-sensitized solar cells

“…Despite decades of research on photochromes, their use in photovoltaics is very recent. 19 However, these compounds could be particularly interesting for the design of semi-transparent devices because their reversible transformation between the two forms with different absorption would allow obtaining solar cells whose transparency could be modulated according to the light intensity. 20 Such a property would be particularly appreciable in Building Integrated Photovoltaics (BIPV).…”

New organic dye-sensitized solar cells based on the D–A–π–A structure for efficient DSSCs: DFT/TD-DFT investigations

“…Therefore, resorting to renewable and low-cost energy sources that can help reduce environmental pollution emissions has become the most appropriate option for future energy needs. [1][2][3] Recently, dye-sensitized solar cells (DSSCs) (or Grätzel cells) have been widely used as a new alternative to meet the growing energy demand for safe environmentally friendly, natural, and economical resources, [4][5][6] allowing the opportunity for converting solar energy into electricity with an efficiency of more than 13%. 7 The engineering design of DSSCs is based on using photosensitive materials in solar cells; generally, a DSSC includes four main components: the photoanode, 8 the cathode, 9 the electrolyte, and the sensitizer.…”
