A bifacial module can produce additional energy by converting solar energy to electrical energy from both sides of the module. Despite the advantages of higher energy yield provided by the bifacial structure, the front side performance of these modules is lower compared to the standard glass/backsheet modules due to the loss in the cell-gap region and the near infrared light escaping through the bifacial modules. This study investigates the selective use of coating on the rear glass to recapture the light while maintaining the bifaciality of the module. To recapture the light loss in between cell-gap region, the reflective coating is printed selectively at only the cell-gap region. To recapture the near infrared escaping the bifacial cell and module, specially engineered coating to reflect the near infrared light is printed on the rear glass.
Dr. Yong Sheng KHOO is the head of PV Module Development group at SERIS. He has more than 5 years of experience in PV module development and testing (both indoor and outdoor). He obtained his Ph.D. degree from Graduate School for Integrative Science and Engineering, National University of Singapore while working as post-graduate researcher at SERIS in the field of solar module and developed new module technologies such as glass-glass modules. He also holds a B.S and M.Eng degree in Mechanical & Aerospace Engineering from Cornell University, USA.
