Dr. Aydin presents "Ultra-Efficient Perovskite/Silicon Tandem Solar Cells" at e-Conversion Conference in Venice

September 26, 2024

Dr. Erkan Aydin recently delivered an invited talk at e-Conversion conference in Venice, hosted by the Center for NanoScience (CeNS). This event brought together leading scientists and young researchers from the fields of physics and chemistry to discuss groundbreaking advancements in nanometer-scale science.

Dr. Aydin's presentation focused on ultra-efficient perovskite/silicon tandem solar cells, a cutting-edge topic in solar energy research. Over the last decade, tandem cells have reached remarkable power conversion efficiencies (PCEs) of up to 34%, with continuous record-breaking achievements. His talk highlighted the development of a solution-processed perovskite subcell integrated on top of industry-standard textured silicon heterojunction cells, achieving an impressive PCE of 33.7%.

Key innovations presented included:

• A dielectric interlayer introduced between perovskite and fullerene contacts, mitigating induced defect states.
• Enhancements to the recombination junction with ultrathin indium zinc oxide electrodes and self-assembled monolayers.
• Optimization of contact design to minimize parasitic absorption and reflection losses.
• The use of an additive in the 1.68 eV perovskite absorber for improved phase homogeneity.

This talk provided an in-depth look into material properties and device integration perspectives, underscoring the importance of both efficiency and durability in advancing tandem solar cell technology. The event proved to be an invaluable platform for fostering collaboration and sharing knowledge within the nano-science community.
