Explore how industry-level innovations in solar cell design and manufacturing—PERC, TOPCon, and HJT—can be optimized for performance, cost, and complexity in a real-world engineering context.
Solar energy is a fast-growing sector that depends on ongoing improvements in solar cell efficiency and manufacturing performance. In this Build Project, you’ll step into the role of a process engineer exploring three leading solar cell technologies: PERC, TOPCon, and HJT. You’ll learn industry practices, process control and characterization method, and get exposure to improvements in process flow. You’ll be introduced to techniques used in modern solar manufacturing like lifetime testing (WCT-120), optical profiling, and others characterization tool. Guided by a professional in the field and with a real case study, you will be more familiar with troubleshooting process bottlenecks and improving solar cell performance—just like engineers do in leading solar manufacturing environments.
By the end of the project, you will be able to:
Explain how solar cells generate energy and compare three major cell technologies (PERC, TOPCon, HJT).
Understand the process differences for different solar cell technologies (PERC, TOPCon, HJT)
Process control methods used in the solar cell manufacturing industry to improve process stability.
Understand key process tools like the ellipsometer, reflectometer, WCT-120, and ECV profiling.
Apply engineering reasoning to propose ways to enhance solar cell yield and cost-effectiveness.
Meet your team, review expectations, and walk through the goals, structure, and deliverables of the project.
Learn how solar cells generate electricity and compare the structures of PERC, TOPCon, and HJT technologies.
Walk through each step of the PERC solar cell manufacturing process. Focus on technical details, challenges, and optimization strategies.
Understand the manufacturing steps of HJT & Topcon solar cells and highlight key innovation.
Explore RCA, SPC, PFMEA through solar cell case studies and related to quality improvement
Analyze where cost arises and how to minimize it through design or materials .
Explore tools like reflector meter, 4probe tester, WCT120, SunVOC, microscope, PL, EL, QE, TLM and how it helps to study the Solar cell.
Deliver final presentation, share project reflections, and gather feedback from peers and the Fellow.
