Röhr,Sarah Holliday,Andrew Wadsworth,Sarah Lockett,Marios Neophytou,Christopher J. M. Emmott,Jenny Nelson,Christoph J. Brabec,Aram Amassian,Alberto Salleo,Thomas Kirchartz,Thomas Kirchartz,James R. Durrant,Iain McCulloch,Iain McCulloch +22 more
TL;DR: This work demonstrates highly efficient and stable solar cells using a ternary approach, wherein two non-fullerene acceptors are combined with both a scalable and affordable donor polymer, poly(3-hexylthiophene) (P3HT), and a high-efficiency, low-bandgap polymer in a single-layer bulk-heterojunction device.
Journal ArticleDOI

Durrant,Iain McCulloch,Iain McCulloch +18 more
TL;DR: Non-fullerene acceptors with optimized energy levels enable 10% efficient solar cells with reduced voltage losses <0.6 V.
Journal ArticleDOI

TL;DR: In this paper, a wide range of commonly used CTLs, including various hole-transporting polymers, spiro-OMeTAD, metal oxides and fullerenes, were studied.
Journal ArticleDOI
Quantifying Losses in Open-Circuit Voltage in Solution-Processable Solar Cells

TL;DR: The reciprocity relation between light absorption and emission is used to explore theoretical and practical performance limits for emerging technologies based on organics and perovskites, and compare them to state-of-the-art systems based on GaAs, c-Si, and CIGS.
Journal ArticleDOI
Recombination via tail states in polythiophene:fullerene solar cells
TL;DR: In this paper, an exponential tail of localized states was incorporated into the density of states for both electrons and holes, allowing recombination to occur between free charge carriers and charge carriers trapped in these states.
