This white paper aims to systematically analyze the industrial breakthrough path and application value of BC technology, so that investors in the photovoltaic industry can have a clear understanding of the technological advantages and development status of BC products from industry to power plant. It provides technical support for industrial investment, power plant design, and component procurement, accelerates the large-scale application of BC technology, and injects deterministic momentum into the global energy transformation.
Core objectives:
At the key node of intergenerational transition of global Photovoltaic (PV) technology, the back contact (BC) cell technology is leading the new-generation PV technology paradigm revolution, becoming the core engine to drive industry cost reduction and efficiency improvement and realize energy transition. This White Paper is intended to systematically analyze the industrialization breakthrough path and application value of BC technology, so that the PV industry, from industry participants to power station investors, can clearly recognize the technological advantages and development status of BC products, provide technical support for industrial investment, power station design and module procurement and selection, accelerate the large-scale application of BC technology, and inject deterministic momentum into the global energy transition.
Value propositions:
BC is the only way for the development of PV technology: The current BC cell mass production efficiency exceeds 27% which is 1.6% higher than TOPCon(tunnel oxide passivated contact), technology maturity and cost competitiveness have beenclose to the traditional technology; its theoretical efficiency limit of 29.1% infinitely approaches the theoretical ceiling of crystalline silicon efficiency; BC is the only technology carrier that can cross the “29%+” threshold, and is thus the only way for all technologies to continue developing efficiently.
The advantages of BC technology have been fully verified: The high efficiency, high power generation capacity and higher reliability of BC technology have been fully verified by authoritative third-party testing and outdoor applications.Full life cycle value has been highlighted: In the current situation, BC technology has obvious investment value advantages in all PV power station scenarios in the world. With the continuous technological progress and cost reduction, BC technology will become the preferred choice for customer investment in all PV power station scenarios.
BC technology shows great potential for sustainable development: As global investment in photovoltaic power stations increasingly focuses on the carbon footprint of modules, the high-efficiency and low-carbon characteristics of BC technology will gradually enhance its competitive edge. In the future, whether it is the rapid improvement of short-term BC efficiency or the development of long-term stacked modules, BC technology has great development potential, ensuring the long-term rapid development of the technical route.
