Copper–zinc–tin–sulfur–selenium (CZTSSe) is a promising thin‑film PV material but suffers efficiency loss when scaled due to film thickness nonuniformity. Chinese researchers developed a solution‑based coating process suitable for large‑area continuous production, producing highly uniform CZTSSe films on 10 cm² substrates and delivering a PV module conversion efficiency of 13.0%, a world record for this type of module.

Trump said the United States "desperately needs" Canadian aluminum, adding the U.S. lacks sufficient domestic supply and that "most of our aluminum comes from Canada." He proposed building an aluminum plant in Inola, Oklahoma on social media, warning "if not approved, the plant will be moved elsewhere." The remarks come as a U.S.-Canada trade dispute intensifies over Trump's 50% metals tariffs. More than half of U.S. annual aluminum consumption is sourced from Canada; talks last week reportedly nearly reached a deal to halve the tariffs but faced opposition from U.S. steel and aluminum producers urging the administration not to make concessions to Canada.
