STS Released its Initial Version of Independent Report on Solar N-Type Technology and Manufacturing Landscape

Over the past few decades, solar power has gained popularity as a source of clean energy, with silicon-based solar modules making incremental advancements in conversion efficiency and durability. The adoption of bifacial modules, laser-cut cells, and multi-busbars technology has further improved module performance on an industrial scale.

However, the Passivated Emitter and Rear Cell (PERC) technology that underlies most crystalline silicon cells is approaching its practical limits. To overcome this, the industry has started transitioning to n-type technologies, with Tunnel Oxide Passivated Contact (TOPCon) and Heterojunction Technology (HJT) emerging as promising candidates.

At STS, we’re committed to helping our clients understand the manufacturing landscapes of these new technologies. That’s why we’re excited to announce the release of our independent report on TOPCon and HJT. This report provides a comprehensive analysis of the distinguishing features of these two n-type technologies, as well as their advantages over PERC in terms of cell efficiency, field performance, and longevity.

Are you buying n-type modules? This report summarizes what buyers need to know before they pull the trigger on this promising, yet still relatively new technology.
