A new article, "VOC Improvement in Broadband (Ag,Cu) (In,Ga)Se2 Solar Cells for Voltage-Matched ACIGS/Si Tandem Modules," co-authored by Roltec R&D team leaders has just been published in the highly regarded industry journal Solar Energy Materials and Solar Cells. The article is the result of an expanded collaboration with European scientists focused on the SITA project.
This paper focuses on investigating the role of absorber temperature increase, surface treatment, and the effect of rubidium fluoride (RbF) post-depositional treatment on the VOC of broadband ACIGS solar cells on transparent substrates and their integration into voltage- and area-matched two-terminal ACIGS/Si tandems. The authors present the first experimental demonstration of a voltage- and area-matched two-terminal bifacial ACIGS/Si tandem module with the implementation of a fully laser-coupled top ACIGS submodule. In this module, unlike more common series-connected tandem systems limited by current matching conditions, the 2T circuit architecture enables additional power amplification under variable bifacial illumination.
