Reducing Energy Disorder of Hole Transport Layer by Charge Transfer Complex for High Performance p-i-n Perovskite Solar Cells

ADVANCED MATERIALS, 33(13).

By: G. Xu*, R. Xue*, S. Stuard n, H. Ade n, C. Zhang*, J. Yao*, Y. Li*, Y. Li*

author keywords: energy disorder; high mobility; hole transport; molecular packing; p– i– n planar perovskite solar cells
TL;DR: The resultant HTL exhibits a reduced energy disorder, which simultaneously promotes hole transport in the HTL, hole extraction at the interface, energy level alignment, and quasi-Fermi level splitting in the device, demonstrating that the CTC strategy is an effective way to reduce the energy disorder in HTLs and to improve the performance of planar pero-SCs.

A molecular interaction-diffusion framework for predicting organic solar cell stability

NATURE MATERIALS, 20(4), 525-+.

By: M. Ghasemi n, N. Balar n, Z. Peng n, H. Hu n, Y. Qin n, T. Kim n, J. Rech*, M. Bidwell* ...

MeSH headings : Diffusion; Electric Power Supplies; Kinetics; Models, Chemical; Organic Chemicals / chemistry; Polymers / chemistry; Sunlight; Thermodynamics
TL;DR: It is discovered that the diffusion of an NF-SMA into the donor polymer exhibits Arrhenius behaviour and that the activation energy Ea scales linearly with the enthalpic interaction parameters χH between the polymer and the NF- SMA, and the thermodynamically most unstable, hypo-miscible systems are the most kinetically stabilized.
