Libertas Study

The Libertas study shows that Germany and the EU, due to their technological leadership, can establish a significant photovoltaic (PV) industry with tens of thousands of jobs in the coming years. Currently, China produces over 90% of PV modules and sells them below cost. A substantial PV industry in Germany and Europe requires financial support for both investment and operating costs. A capacity of 10-20

Comparative Global PV Manufacturing Cost and Sustainable Pricing Assessment: China, Southeast Asia, India, USA, and Europe

In the fast-developing photovoltaics (PV) industry, assessing manufacturing costs is a challenging task. Technology developments need to be constantly followed and technology parameters as well as material flows and consumption as well as pricing to be updated accordingly. The authors of this work have been developing detailed bottom-up PV manufacturing cost models for different PV production technologies and stages [1]-[4] and been publishing various cost

Pathway to TBC

PV cell technology follows innovation cycles of approximately 5–7 years. Given the longer planning and ramp‑up timelines typical for Western manufacturing facilities, future upgradeability must be a core design consideration from the outset. The industry is expected to move beyond TOPCon towards TOPCon Back Contact (TBC) cells as the next technological evolution. While multiple upgrade pathways exist, they vary significantly in terms of capacity impact,
