چکیده
As the device performance and stability of polymer solar cells strongly depend on interfacial charge extraction layers, hole transport layer (HTL) properties are crucial. Furthermore, unfavorable interactions with electrode or photoactive should be screened prevented. Organic conventional architecture by varying HTL material stack systematically between PEDOT:PSS a sol–gel-derived tungsten oxide (WO3) investigated. The impact various HTLs in is investigated optical electrical characterization. Interestingly, triple-layer WO3/PEDOT:PSS/WO3 configuration results best specifically compared use pristine WO3 layers. triple also shows an increased reproducibility lifetime, which, combined improvement efficiency, can keys for expectable revenue.

Enhanced performance of polymer solar cells by dipole-assisted hole extraction
Polymer solar cells (PSCs) with different anode buffer layers were fabricated to investigate dipoleassisted hole extraction on the performance improvement of PSCs. The power conversion efficiency (PCE) of PSCs was increased from 4.77% to 6.18% with 29.6% improvement due to the increased short circuit current density (Jsc) from 12.00 to 15.65 mA/cm 2 induced by the oriented LiF dipole-assisted h...

Abstract In this study, we demonstrate that few-layered graphene quantum dots (F-GQDs) can be used as hole-extraction layer (HEL) for high efficiency polymer solar cells (PSCs). As a new class of HEL material, graphene oxide (GO) is not suitable for polymer solar cells (PSCs) based on highly efficient donor polymers due to...
