Hisham Maddah is an independent researcher and a faculty member working with the Chemical Engineering Department at King Abdulaziz University in Rabigh (KAU-Rabigh). He has been awarded a full scholarship and received his PhD in “Naturally-Sensitized Photoanodes for Molecular Photovoltaics” from the University of Illinois at Chicago (UIC) by Summer 2020. He has completed his MS and BS in Chemical Engineering from the University of Southern California (USC) in 2017 and KAU in 2012, respectively. Dr. Maddah has worked for two years in the Chemical Business Department in Saudi Aramco (2012 – 2014). He is an expert in organic-inorganic dye-sensitized solar cells for solar energy harvesting. His research interests include mini-passive solar stills, machine learning for solar-desalination systems, membrane separation, capacitive deionization, and activated carbons for water treatment, separation technologies, and higher education administration. He and his lab members are also experienced in the synthesis of low-dimensional semiconductors, fabrication of heterojunction diodes, utilization of natural sensitizers, Ti-based perovskites, and graphene for cost-effective and environmental-friendly energy harvesting applications. He is the recipient of the “Best Poster Award” in the 2nd Annual Graduate Research & Career Symposium at UIC. He received the SACM publication prize seven times for his distinguished contribution. Dr. Maddah has published more than 50 articles and 3 book chapters in reputed international peer-reviewed journals and conferences including Renewable Energy, Renewable & Sustainable Energy Reviews, ACS Applied Materials & Interfaces; and co-arranged 5 outreach activities on third-generation solar cells.
