Abstract

Highlights: Performance of bifacial modules are studied experimentally in indoor and outdoor. Energy yield gain of different bifacial modules varies with environmental factors. HJT module shows the highest performance due to its bifaciality and coefficient. Abstract: The tunnel oxide passivated contacts (TOPCon) cell, and the Si heterojunction solar cell (HJT) based on Si cells with high-efficiency potential have recently been transferred from the laboratory to manufacturing technology. However, the harvested energy of advanced bifacial modules has not yet been proved in the field. Our project aims to present an experimental study on the energy yield performance of the TOPCon bifacial PV module compared to HJT and PERC bifacial PV modules in the southernmost of China, Hainan province. The experimental results have proven that the energy yield performance of HJT bifacial modules is 8.79% higher than that of the PERC modules, and the energy yield gain of the TOPCon modules is 5.55% higher compared to PERC modules.
