Laser-Scribing Patterning for the Production of Organometallic Halide Perovskite Solar Modules

Christophe Ballif, Jun Ho Yum, Arnaud Walter, Sylvain Nicolay, Laurent Fabien Hubert Sansonnens, Julien Claude Bailat, Soo-Jin Moon, Mustapha Benkhaira

Efficiencies of solar cells based on organometallic halide perovskite absorber material have dramatically increased over the past few years. Most of efficiencies reported so far have, however, been obtained on solar cells with very small lab-scale area of ...

Monitoring water vapour penetration using a contactless technique

Christophe Ballif, Laure-Emmanuelle Perret Aebi, Mustapha Benkhaira

Some layers of thin film photovoltaic modules maybe critically sensitive to moisture. In this study we present a new tool for monitoring the effect of moisture using a particular Transparent Conductive Oxide (TCO) as a sensor. The moisture content of the e ...
