Journal ArticleDOI
The Consequences of Kesterite Equilibria for Efficient Solar Cells
TL;DR: It is shown that understanding the formation reaction of the kesterite absorber is the key to control the growth process and to drastically improve the solar cell efficiency and it is demonstrated that this knowledge can be used to simplify the four-dimensional parameter space to an easy and robust two-dimensional process.
Journal ArticleDOI
The impact of energy alignment and interfacial recombination on the internal and external open-circuit voltage of perovskite solar cells
Martin Stolterfoht,Pietro Caprioglio,Pietro Caprioglio,Christian M. Wolff,José A. Márquez,Joleik Nordmann,Shanshan Zhang,Daniel Rothhardt,Ulrich Hörmann,Yohai Amir,Alex Redinger,Lukas Kegelmann,Fengshuo Zu,Fengshuo Zu,Steve Albrecht,Norbert Koch,Norbert Koch,Thomas Kirchartz,Michael Saliba,Thomas Unold,Dieter Neher +20 more
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
The perovskite/transport layer interfaces dominate non-radiative recombination in efficient perovskite solar cells
Martin Stolterfoht,Pietro Caprioglio,Christian Wolff,José A. Márquez,Joleik Nordmann,Shanshan Zhang,Daniel Rothhardt,Ulrich Hörmann,Alex Redinger,Lukas Kegelmann,Steve Albrecht,Thomas Kirchartz,Michael Saliba,Thomas Unold,Dieter Neher +14 more
TL;DR: In this article, the quasi-Fermi level splitting (QFLS) of perovskite/CTL heterojunctions was measured to quantify the non-radiative interfacial recombination current for a wide range of commonly used CTLs, including various hole-transporting polymers, spiro-OMeTAD, metal oxides and fullerenes.
Journal ArticleDOI
The band gap of Cu2ZnSnSe4: Effect of order-disorder
Germain Rey,Alex Redinger,Jan Sendler,Thomas Paul Weiss,Maxime Thevenin,Mael Guennou,B. El Adib,Susanne Siebentritt +7 more
TL;DR: In this paper, the order-disorder transition in kesterite Cu2ZnSnSe4 (CZTSe), an interesting material for solar cell, has been investigated by spectrophotometry, photoluminescence (PL), and Raman spectroscopy.
Journal ArticleDOI
Detection of a ZnSe secondary phase in coevaporated Cu2ZnSnSe4 thin films
Alex Redinger,Katja Hönes,Xavier Fontané,Victor Izquierdo-Roca,Edgardo Saucedo,Nathalie Valle,Alejandro Pérez-Rodríguez,Susanne Siebentritt +7 more
TL;DR: In this paper, Raman measurements on the as grown films are used to study the near surface region and the CZTSe/Mo interface, after mechanically removing the thin film from the Mo coated glass.
