Alwani Imanah Rafieh, a 3rd year PhD student from CAMES UBD conducted a month long fieldwork research at Kyoto University (KU) in September 2017. Alwani was researching on the use of mesoporous TiO2 in perovskite solar cell (PSC) application. In KU Alwani is supervised by Assoc. Prof. Astushi Wakamiya from the Institute for Chemical Research (ICR). Alwani is an alumni of the AUN-KU Joint Supervision Single Master Degree Program.
The objective of Alwani’s research is to enhance the power conversion efficiency of PSC. In her recent fieldwork, she fabricated PSC using doped mesoporous TiO2. Alwani looks forward to outcome of her field work where she is hoping the data will shed light on phenomena that have yet to be explained in this field.
PSC is the fastest growing field of solar cell research. In addition, PSC, like Dye Sensitized Soar Cell (DSSC), provides a low economic entry barrier to solar cell fabrication. The latest highest efficiency of PSC achieved is 22.1% (Yang, et. al, 2017). With a comparable power efficiency value as conventional silicon (Si) based solar cells and the low cost entry to PSC fabrication, interests in PSC is growing towards the development of tandem Si solar cell and PSC. The downside of PSC, however, is the instability of perovskite solar cells over time, and the reproducibility of the cell performance.
