Zhi-Kuang Tan,Reza Saberi Moghaddam,May Ling Lai,Pablo Docampo,Ruben Higler,Felix Deschler,Michael Price,Aditya Sadhanala,Luis M. Pazos,Dan Credgington,Fabian C. Hanusch,Thomas Bein,Henry J. Snaith,Richard H. Friend +13 more
TL;DR: It is shown, using photoluminescence studies, that radiative bimolecular recombination is dominant at higher excitation densities, Hence, the quantum efficiencies of the perovskite light-emitting diodes increase at higher current densities.
Proceedings ArticleDOI
Photon recycling in Lead-Iodide Perovskite solar cells(Conference Presentation)
Luis M. Pazos,Monika Szummilo,Robin Lamboll,Johannes M. Richter,Micaela Crespo-Quesada,Mojtaba Abdi-Jalebi,Harry J. Beeson,Milan Vrućinić,Mejd Alsari,Henry J. Snaith,Bruno Ehrler,Richard H. Friend,Felix Deschler +12 more
TL;DR: In this paper, the authors mapped the propagation of photogenerated luminescence and charges from a local photoexcitation spot in thin films of lead tri-iodide perovskites using a confocal microscopy setup with independent excitation and collection objectives.
Journal ArticleDOI
A Silicon-Singlet Fission Parallel Tandem Solar Cell Exceeding 100 % External Quantum Efficiency
TL;DR: In this article, a parallel-connected tandem solar cells based on down-conversion via singlet fission was proposed to increase the theoretical power conversion efficiency to 45% with superior stability under changing sunlight conditions in comparison to traditional series tandems.
Journal ArticleDOI

TL;DR: In this article, an insulating alumino-silicate shell around the TiO2 nanocrystals, which reduces interfacial recombination, and the introduction of a mesoporous SiO2 buffer layer between the top electrode and TiO 2, which acts as a permanent insulating barrier between theTiO2 and the metal electrode, preventing shunting.
