Efficient ternary blend bulk heterojunction solar cells with tunable open-circuit voltage.

TL;DR: It is suggested that ternary blends provide a potentially effective route toward maximizing the attainable J(sc)V(oc) product in BHJ solar cells and that with judicious selection of donor and acceptor components, solar cells with efficiencies exceeding the theoretical limits for binary blend solar cells could be possible without sacrificing the simplicity of a single active-layer processing step.
Journal ArticleDOI

Origin of the tunable open-circuit voltage in ternary blend bulk heterojunction organic solar cells.

TL;DR: The combination of molecular excitations that can harvest a wide range of photon energies and electronic alloy states that can adjust the open-circuit voltage provides the underlying basis of ternary blends as a platform for highly efficient next-generation organic solar cells.
Journal ArticleDOI

Compositional Dependence of the Open-Circuit Voltage in Ternary Blend Bulk Heterojunction Solar Cells Based on Two Donor Polymers

TL;DR: This work shows that upon optimization of the overall polymer:fullerene ratio at each polymer:polymer ratio, high FF, regular variations in V(oc), and enhanced J(sc) are possible throughout the ternary blend composition regime.
Journal ArticleDOI

Optimization and simplification of polymer–fullerene solar cells through polymer and active layer design

TL;DR: In this article, random poly(3-hexylthiophene) (P3HT) analogs and their application in binary and ternary blend polymer-fullerene solar cells are discussed.
Journal ArticleDOI

Influence of the Ethylhexyl Side-Chain Content on the Open-Circuit Voltage in rr-Poly(3-hexylthiophene-co-3-(2-ethylhexyl)thiophene) Copolymers

TL;DR: In this paper, a simple and modular model system of random copolymers based on rr-P3HT was designed to address some of these questions, and the influence of increasing amounts of branched 2-ethylhexyl side chains (10, 25, and 50%) on conjugated-polymer:fullerene solar cell performance, and especially the Voc and Jsc, was investigated.
