Blade coated P3HT:non-fullerene acceptor solar cells: a high-throughput parameter study with a focus on up-scalability

Abstract

Fast screening of performance and stability of organic solar cells is made through the use of thickness and thermal gradients, as well as different deposition temperatures and solvents.

Novel cost-effective acceptor:P3HT based organic solar cells exhibiting the highest ever reported industrial readiness factor

“…THN, BrA, and o-DCB have previously been utilized with P3HT: O-IDTBR with great success. 38,39 However, from the obtained results herein (Fig. 5B), it can be seen that only DIO or o-DCB with PCE of 1.1% enhances the device efficiency above the CB:CF base solvent mixture.…”

Molecular Engineering and Morphology Control of Polythiophene:Nonfullerene Acceptor Blends for High‐Performance Solar Cells

“…Recent studies demonstrated that replacing alkyls with oligo(ethylene glycol) side chains is able to generate water or alcohol soluble conjugated polymers and acceptors. [184][185][186][187] In addition, scalable coating methods such as blade coating, [188][189][190][191][192] and slot-die coating [193][194][195][196][197] and roll-to-roll printing [198,199] should be more extensively explored. 6) Development of PT-based all-polymer solar cells: All-polymer solar cells exhibit unique advantages, such as excellent mechanical property, good morphological stability, and readily tunable solution viscosity.…”

Structure dependent photostability of ITIC and ITIC-4F

“…This type of hot stage produces a controlled temperature gradient which is then transferred to the sample, enabling the production of films with a lateral thermal annealing gradient. 28 Characterization UV-vis absorption spectra were recorded using a Hitachi U-3000 spectrophotometer. Optical microscopy images were obtained using an OPTIKA B-600 MET microscope in crossed polarizer configuration.…”

“…The advantage of this approach in stability studies is two-fold, as it allows for a significant saving of lab time and material use. 19,[28][29][30]…”
