Article Synopsis
- Blends of semiconducting and ferroelectric polymers are being researched for use in resistive memories and organic photovoltaics due to potential improvements in power conversion efficiency through localized electric fields.
- The study focuses on a block copolymer consisting of a ferroelectric component (P(VDF-TrFE)) and a semiconducting component (P3HT) to create smooth thin films, overcoming processing challenges encountered when using these materials individually.
- Despite the integration of these materials, the photovoltaic performance of the resulting solar cells was found to decrease due to unfavorable nanomorphology, with lithium fluoride's role in modifying device performance also being investigated.
The last decade saw myriad new donor polymers, among which benzodithiophene-co-thienothiophene polymers are attractive due to their relatively high power conversion efficiency in bulk heterojunction solar cells. We examine the effect of UV-light on the stability of these polymers. The relationship between the polymer chemical structure and the UV-stability of the cells is explored on the one hand, and on the other hand, the effect of additives on their UV-stability: 1,8-diiodooctane against 1-chloronaphthalene in the cells and 1,8-octanedithiol in solution.

In the past five years alone, more than hundreds of NFAs with applications in organic photovoltaics (OPVs) have been synthesized, enabling a notable current record efficiency of above 15%. Hence, there is a shift in interest toward the use of NFAs in OPVs.
