Extract architecture, specimen area, reported efficiency measurement and stability test evidence. Keep certified efficiency separate from the performance of the specimen used in stability tests. Distinguish component films, single-junction cells and complete tandems. Record missing conditions as not reported and inaccessible methods as not accessed. Do not rank devices from incompatible tests or infer details from review articles.",
