Understanding Postdeposition Treatments of Hole‐Transporting Self‐Assembling Molecules for Perovskite/Silicon Tandem Solar Cells

Advanced Functional Materials, Volume 35, Issue 49, December 2, 2025.
The influence of postdeposition treatments on the formation of self‐assembling (mono)layers commonly utilized as hole transport layers in perovskite‐based solar cells is thoroughly investigated. The implementation of a washing step and an annealing step at temperatures exceeding the current literature standards leads to an enhanced layer quality and ...

Indentation size effect for spherical nanoindentation on nanoporous gold

, 2018
We find that the indentation size effect (ISE) occurs during spherical indentation on nanoporous gold (np-Au). The hardness increases as the indenter radius decreases at a fixed representative strain.

Indium‐Free Recombination Layer for Perovskite‐Based Multijunction‐Solar‐Cells‐ with Improved Performance Using Sputtered Zinc Tin Oxide

Small, Volume 21, Issue 50, December 17, 2025.
In two‐terminal multijunction solar cells, the subcells are connected in series through recombination layers whose electro‐optical properties directly influence all photovoltaic parameters. Here, we introduce low‐temperature sputtered zinc tin oxide (ZTO) as an indium‐free recombination layer for perovskite‐based multijunction devices.
