Quantifying Losses in Open-Circuit Voltage in Solution-Processable Solar Cells
Jizhong Yao,Thomas Kirchartz,Thomas Kirchartz,Michelle S. Vezie,Mark A. Faist,Wei Gong,Wei Gong,Zhicai He,Hongbin Wu,Joel Troughton,Trystan Watson,Daniel Bryant,Jenny Nelson +12 more
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.
Identifying Dominant Recombination Mechanisms in Perovskite Solar Cells by Measuring the Transient Ideality Factor
Philip Calado,Dan Burkitt,Jizhong Yao,Joel Troughton,Trystan Watson,Matthew J. Carnie,Andrew M. Telford,Brian O'regan,Jenny Nelson,Piers R. F. Barnes +9 more
TL;DR: In this paper, the authors used drift-diffusion simulations to identify the dominant recombination mechanism in perovskite solar cells (PSCs) following device preconditioning with a forward bias.
Relating Recombination, Density of States, and Device Performance in an Efficient Polymer:Fullerene Organic Solar Cell Blend
Steven A. Hawks,Florent Deledalle,Jizhong Yao,Dylan G. Rebois,Gang Li,Jenny Nelson,Yang Yang,Thomas Kirchartz,James R. Durrant +8 more
TL;DR: In this paper, the authors explore the interrelation between density of states, recombination kinetics, and device performance in effi cient poly(4,8-bis-(2-ethylhexyloxy)- benzo(1,2-b:4,5-b')dithiophene-2,6-diyl-alt-4-(2,ethyl hexyloxy-1-one) thieno(3,4-b)thieno (3,6)-phenyl-C 71 -butyric acid methyl ester

TL;DR: In this article, the dominant recombination mechanism in two structurally similar CH3NH3PbI3 devices containing either mesoporous Al2O3 or TiO2 layers can be identified from the signature of the transient ideality factor following application of a forward bias, Vpre, to the device in the dark.
