Soft-landing of IZRO electrodes eleminates buffer layers

13 January, 2021

Previously, Zr‐doped In2O3 (IZrO) transparent conductive oxides electrodes have been successfully implemented for perovskite/silicon tandem solar cells by our group. (see Aydin, Erkan, et al. "Zr‐Doped Indium Oxide (IZRO) Transparent Electrodes for Perovskite‐Based Tandem Solar Cells." Advanced Functional Materials 29.25 (2019): 1901741.).

Here, KPV-LAB researcher Dr. Erkan Aydin and Prof. Stefaan De Wolf contributes a publication led by the University of Twente and collaborators from TNO/Solliance. In this study, Smirnov et al. developed a pulsed-laser deposited IZRO electrodes successfully at low-temperature values and implemented them in semitransparent perovskite solar cells.

This study revealed that the PLD technique can be used as a "soft" deposition technique for the "sensitive" perovskite solar cells. This opens an opportunity to utilize PLD grown IZRO films on perovskite/silicon tandem solar cells without additional buffer layers.
