Musk-linked supplier tour in China spotlights solar push; Tesla (TSLA) probes heterojunction, perovskite

Musk-linked supplier tour spotlights solar supply push

Tesla and SpaceX teams are visiting Chinese photovoltaic suppliers as they probe advanced solar-cell technologies that could underpin large-scale capacity builds, Chinese state-backed and industry outlets report. Cailianshe and 21st Century Business Herald say delegations focus on equipment manufacturing, silicon wafers, battery modules and next‑generation cell approaches such as heterojunction and perovskite. JinkoSolar confirms a Musk-linked visit but declines to elaborate; Tesla and SpaceX do not immediately comment and international outlets are unable to independently verify the full scope.

The delegations’ interest aligns with Elon Musk’s previously stated aim to build 100 gigawatts of U.S. solar‑cell capacity, and signals Tesla’s continued push to secure more of its upstream energy supply chain. Heterojunction and perovskite techniques promise higher conversion efficiencies and potentially lower levelised costs if throughput and durability challenges are solved. Suppliers and engineers caution that industrialising these methods requires new manufacturing lines, wafer sourcing and rigorous quality control at scale.

Industry participants say the visits reflect broader strategic moves by major technology firms to integrate power generation and storage more tightly with computing and transport businesses. Analysts note any durable shift toward Chinese production or new cell chemistries hinges on concrete purchase agreements, resolved perovskite manufacturing challenges and demonstrable long‑run reliability. Until such commercial commitments appear, supplier engagements remain exploratory verifications of technology and manufacturing readiness rather than immediate procurement decisions.

Global financial snapshot and AI tensions

Switzerland’s UBS reports a robust quarter, with CEO Sergio Ermotti saying fourth‑quarter profit rises year‑on‑year, underscoring pockets of resilience in the banking sector as firms weigh balance‑sheet strength ahead of policy decisions.

Meanwhile, market attention stays fixed on artificial intelligence partnerships and dealmaking. Nvidia’s Jensen Huang denies any rift with OpenAI after reports about a planned investment pause, and high‑profile merger talk involving xAI and SpaceX adds to scrutiny over how tech incumbents and newcomers are reshaping supply chains and energy demand.
