  "summary": "Independent review by claude-independent-prior-art-reviewer-20261106: Printed solar on flexible rolls is demonstrated but nowhere near the Main KPI of 500,000,000 square metres installed per year. The record fully roll-to-roll printed perovskite modules are 11 percent at 50 square cm (Nature Communications 2024) and 11 to 12 percent at 100 square cm on a commercial-scale printer in 2025 (https://taiyangnews.info/australias-csiro-led-team-reports-new-efficiency-record/), and a 2026 Advanced Science review notes flexible modules remain under 22 percent with open problems in film quality at high throughput, long-term stability and integration cost (https://eprints.whiterose.ac.uk/id/eprint/240548/). TNO's spin-out Perovion plans the first roll-to-roll perovskite factory for construction in 2030 (https://www.tno.nl/en/newsroom/2026/03/tno-launches-perovion-technologies/). Heliatek's IEC-certified HeliaSol organic film is the main commercial printed product, from a line designed for about 1 to 2 million square metres a year, and the organic solar market is only about US$0.3 to 2 billion with large-area modules losing 20 to 30 percent efficiency versus cells (https://heliatek.com/en). Honest limit: roll-to-roll coating of perovskite and organic cells is published and partly commercial, so tasks that reproduce the CSIRO or Heliatek processes are known answers; the open work is printed modules with silicon-competitive efficiency, outdoor lifetime and cost at hundreds of millions of square metres, and each task needs its own basis.
