Perylene derivatives for solar cells and energy harvesting: a review of materials, challenges and advances

Comparison of fluorene, silafluorene and carbazole as linkers in perylene monoimide based non-fullerene acceptors

“…18 So far, mainly perylene diimides (PDI), substituted at the bay position were investigated as NFAs in solar cells. [19][20][21][22][23][24][25] The major issue of PDIs is their pronounced agglomeration, which leads to large crystallites within the blend and hence low device performance. [26][27][28] To tackle this issue, twisting the PDI is necessary by introducing side groups or by ring fusion.…”

Excitation transport in molecular aggregates with thermal motion

“…in dye-sensitized solar cells 5,6 or thin-film optical and optoelectronic devices 7 . In all of these, molecular aggregates facilitate the absorption of light and subsequent transfer of the absorbed energy to a reaction centre 8,9 in the form of an electron-hole pair known as exciton. This transfer of excitation relies on the long range dipole-dipole interactions between the monomers in the aggregate.…”

Degradable and Dissolvable Thin-Film Materials for the Applications of New-Generation Environmental-Friendly Electronic Devices

“…This copolymer was first synthesized using a hollow rod-like Mg(OH) 2−x F x sol with the solvothermal method, and was then fabricated to the organic-inorganic hybrid hydrophobic Mg(OH) 2−x F x− MTES copolymer. Furthermore, preparation methods like solvothermal [60,61], photolithography [62], the laser ablation in liquids (LAL) method [63], solvent evaporation [64], interfacial reaction [65], phase inversion [20], spin-coating [66], vapor deposition [67], solution deposition [68], and printing [30] are also widely used.…”

“…Over the past two decades, there have always been new applications, which are not easy to realize with traditional electronics with inorganic semiconductors. It has resulted in pushing people to do more research on organic transistors [170,171], photovoltaic cells, energy harvester [61], light-emitting diodes [172], electronic devices [173], sensors [174], and memristors [20]. Compared with inorganic counterparts, organic technologies can address energy and cost inefficiency issues.…”
