Developing PV modules with higher power,energy yield,and improved reliability (i.e.less module degradation) are the primary approaches to effectively reduce the levelized cost of electricity (LCOE) for PV generation.A double-glass module structure is well proven for improving the reliability.At the same time,this module structure enables light harvesting from both sides of the module.Hence,fabricating bifacial modules using bifacial cells is the natural choice for double-glass module structure.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 and improved reliability offered by the double-glass biracial structure,at standard test conditions,these modules have additional power loss compared to the standard glass/backsheet modules.In this study,a detailed power loss characterization for double-glass bifacial modules is presented.From the loss characterization,various advanced techniques such as half-cut cell,multi-busbar,white ceramic coating in the cell-gap region,light reflective ribbon have been explored to develop high power double-glass biracial module.Using various characterization and simulation techniques/tools developed at Solar Energy Research Institute of Singapore,a detailed quantitative analysis of the power gains due to advances techniques is presented.The performance of double-glass bifacial modules by integrating one or more advanced techniques was studied by fabricating several mini-modules and standard 60-cell modules.
