The first year of JSPS Research Scholarship on perovskite FAPbI3 quantum dot solar cells has resulted in significant accomplishments. These include the successful setup of the instrumentation for synthesis, optimization of the spin coating process to achieve homogeneous films, exploration and optimization of synthesis protocols leading to improved Voc and higher PLQY, and surface engineering of quantum dots through a femtosecond laser generated plasma. The upcoming paper submissions to peer-reviewed journals and presentations at international conferences will provide an opportunity to disseminate these findings to the wider scientific community. The insights gained from this research will contribute to the ongoing development of perovskite solar cell technology, facilitating its potential for practical applications.Surface engineering of quantum dots was achieved through the utilization of a femtosecond laser generated plasma. This technique allowed for precise adlayer deposition of a thin quantum dot layer in a FAPI perovskite solar cell. The surface-engineered quantum dots demonstrated enhanced power conversion efficiency (PCE) and short-circuit current (Isc), indicating improved device performance. Furthermore, indications of a longer lifetime were observed, suggesting increased stability. These significant results will also be presented at upcoming international conferences and published in peer-reviewed journals, showcasing the advancements made in surface engineering techniques for quantum dot solar cells.
