Here, we integrate SCAPS-1D device simulations with machine learning to systematically explore 125 device architectures constructed from five electron transport layers (ETL), five absorbers (including lead-free double perovskites), and five hole transport layers (HTL). A representative subset of configurations is used to train a machine learning (ML) model, which predicts the power conversion efficiency (P","authors_text":"Amirhosein Ahmadkhan Kordbacheh, Neda Nasiri, Seyed Mahdi Mastoor","cross_cats":["physics.app-ph","physics.comp-ph","physics.optics"],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-06-10T13:47:21Z","title":"Multilayer Screening of Double and Conventional Perovskite Solar Cells Using SCAPS-1D and Machine Learning: Optimization of ETL, HTL, and Absorber for High-Efficiency Architectures"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2606.12083","kind":"arxiv","version":1},"verdict":{"created_at":null,"id":null,"model_set":{},"one_line_summary":"","pipeline_version":null,"pith_extraction_headline":"","strongest_claim":"","weakest_assumption":""}},"verdict_id":null}}],"author_attestations":[],"timestamp_anchors":[],"storage_attestations":[],"citation_signatures":[],"replication_records":[],"corrections":[],"mirror_hints":[],"record_created":{"event_id":"sha256:997e341e0dd4fbf44cdb3656b56c91d04660335415db74539bbb6f54b622e0ac","target":"record","created_at":"2026-06-11T01:10:47Z","signer":{"key_id":"pith-v1-2026-05","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","signer_id":"pith.science","signer_type":"pith_registry"},"payload":{"attestation_state":"computed","canonical_record":{"metadata":{"abstract_canon_sha256":"25feb40d907f612ce606011f445e5d059d6fdcf45603018394dee22c900b0870","cross_cats_sorted":["physics.app-ph","physics.comp-ph","physics.optics"],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"cond-mat.mtrl-sci","submitted_at":"2026-06-10T13:47:21Z","title_canon_sha256":"99fe30732eb67b433da68e6ee988f2ed41321061e4cc2a2a7951a2d321452d06"},"schema_version":"1.0","source":{"id":"2606.12083","kind":"arxiv","version":1}},"canonical_sha256":"9252aadf123948d1e214db62d716d0b3d071f56c18461fdd161a988287026ce1","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"9252aadf123948d1e214db62d716d0b3d071f56c18461fdd161a988287026ce1","first_computed_at":"2026-06-11T01:10:47.241067Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-06-11T01:10:47.241067Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"uRf3XBcG9qd+fVFx93eGNJnQFxyyHC5IqOKKxqPvCqvPxW0Os5H2ZbMNVNg7LA+jkxw+tqJI72lmk306n8yTCA==","signature_status":"signed_v1","signed_at":"2026-06-11T01:10:47.241886Z","signed_message":"canonical_sha256_bytes"},"source_id":"2606.12083","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:997e341e0dd4fbf44cdb3656b56c91d04660335415db74539bbb6f54b622e0ac","sha256:a6e558448ae9ebb4738f5a4153aca0116db6c84fe4be10e8dfff6e8c42c39a41"],"state_sha256":"e9b9b3c7354c132ddcc41e1eec7eaa43fc4d3d498201987b334a2cfc07429f84"}
