Monolithic perovskite silicon tandem solar cells with the fully-textured architecture are promising due to their efficient light management scheme as well as compatibility to industrial silicon production lines. To achieve high-efficiency, and more importantly reproducibility, perovskite deposition parameters should be well controlled. In the recently published paper, we look into the impact of perovskite processContinue reading “New Paper- Toward efficient and industrially compatible fully textured perovskite silicon tandem solar cells: Controlled process parameters for reliable perovskite formation”

The highly efficient perovskite-based dual-junction solar cells especially on silicon bottom cell have shown impressive PCE improvement in recent years with world record of 33.9%. Now a new group of perovskite solar cells is emerging: triple-junction solar cells with the potential to surpass the efficiency limit of dual-junction solar cells. In our recent review, weContinue reading “New Paper- Recent Progress in Monolithic Two-Terminal Perovskite-Based Triple-Junction Solar Cells”

Our PhD student Oussama Er-raji along with Dr. Christoph Messmer and their collaborators published a new work where they used various characterisation techniques to investigate loss origins in fully-textured perovskite-silicon tandem solar cells. By feeding the extracted device characteristic parameters into a Sentaurus TCAD opto-electrical model, the study delivered precise steps required to reach theContinue reading “New Paper – Loss Analysis of Fully-Textured Perovskite Silicon Tandem Solar Cells”

In our most recent publication we demonstrate that triple-junction solar cells consisting of perovskite-perovskite-silicon subcells hold considerable promise and have great efficiency potential. We were able to develop a triple-junction solar cell with an open-circuit voltage of over 2.8 volts, using adapted deposition techniques to sucessfully deposit the large number of layers needed for aContinue reading “New Paper – Perovskite/Perovskite/Silicon Triple-Junction Solar Cells reach Open Circuit Voltage over 2.8V”

In her newest paper PhD student Özde Kabaklı published important work to improve the transparent conductive oxide films used in perovskite-silicon tandem solar cells. She and her collaborators were able to reduce the electro-optical losses in these layers. This will help built better tandem solar cells.

PhD student Mina Heydarian and her collaborators published a new study in which they carefully modelled how to increase the current density in tandem solar cells and then optimised the experimental procedures to realise great gains in the current density. These improvements are key to realise highly-efficient perovskite-silicon solar cells. The study also demonstrates theContinue reading “New paper – Increasing the Current Density in Tandem Perovskite-Silicon Solar Cells”
