| dc.description.abstract | The objective of this research is to achieve low-cost high-efficiency (> 23%) commercial-ready bifacial screen-printed n-type Si solar cells through a combination of fundamental understanding, device modeling, technology innovations, and complete cell fabrication. This research involves developing a technology roadmap by device modeling and simulations to achieve > 23% efficiency target followed by development and implementation of required design features such as optimized boron emitter on front and tunnel oxide passivated contact (TOPCon) on the rear side of an n-type silicon wafer, in combination with advanced fine-line screen-printing metallization with floating busbars to attain the efficiency target. In addition, a next-generation industry-compatible double-side passivated contacts solar cell structure is studied and modeled. This cell structure is composed of full area p-TOPCon on the rear and selective area n-TOPCon on the front side of an n-type Si wafer. Detailed modeling using practically achievable material and device parameters shows that ~25.4% efficiency is achievable with this design using traditional screen-printing. | |
