Production not politics, capex not capacity – the new metrics defining U.S. solar manufacturing The landscape for solar PV manufacturing in the United States is set to move from bystander-curiosity to manufacturing-scrutiny. Finlay Coville explores how this transition has come about, why the existing analysis of the manufacturing space has been largely superficial until now, and what tracking a capital expenditure (capex) heavy manufacturing sector looks like in practice.

UNSW, Trina Solar design silver-free back contact PV cell with screen-printed aluminum contacts Researchers from UNSW and Trina Solar developed a silver-free silicon tunnel-back-contact solar cell using dual-polarity screen-printed aluminum contacts on poly-Si/SiOx passivated structures with optimized firing and specialized aluminum-silicon (Al-Si) pastes. The approach enables low-resistance contacts and reduced silver use, but efficiency is still limited by higher Al/Si interfacial recombination, highlighting the need for further contact and interface optimization.
