Unfortunately, the search results provided did not find the article titled "Molecular press annealing enables robust perovskite solar cells" from the journal Science, Volume 391, Number 6781, January 2026. The search results contain articles on similar topics related to the stability of perovskite solar cells, but not the specific article you asked to summarize. In order to create an accurate and factual summary as per your requirements, I would need access to the full text of this particular article. Without it, I would not be able to guarantee accuracy and fact-checking, which are your main requirements.
