It is well known that inclusion of metallic NPs in an active layer can boost the surrounding near-field intensity around them owing to the dipolar localized surface plasmon resonance (LSPR, also called antenna effect), which can increase light absorption by solar cells. However, the use of plasmonic NPs in perovskite solar cells has been barely reported, and it is not known whether inserting plasmonic NPs into a perovskite active layer prod","authors_text":"Kwangjin Kim, Seungwoo Lee","cross_cats":["physics.optics"],"headline":"","license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2018-12-17T08:54:14Z","title":"Plasmonic Metamaterial Perovskite Solar Cells: Fundamental Tradeoffs, Limitations, and Opportunities"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"1812.06655","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":"sha256:6bd61747a2c2c6b7eadd7f116ac131bf7d3527220fa1f69d35fbe945fc9399c2","target":"record","created_at":"2026-05-17T23:58:09Z","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":"43b876ad0eaf2f5ad064c58b80ca9ab8b4436621834295c46a1b0f54ecfd7338","cross_cats_sorted":["physics.optics"],"license":"http://arxiv.org/licenses/nonexclusive-distrib/1.0/","primary_cat":"physics.app-ph","submitted_at":"2018-12-17T08:54:14Z","title_canon_sha256":"2ea93576dbb0758c81e8953e2e4736d99cc3007d00c2661799cb253efad317e7"},"schema_version":"1.0","source":{"id":"1812.06655","kind":"arxiv","version":1}},"canonical_sha256":"835755c43710354574d5b567e6039a18a19dbd04e10d9b3f4d3756be42f9779c","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"835755c43710354574d5b567e6039a18a19dbd04e10d9b3f4d3756be42f9779c","first_computed_at":"2026-05-17T23:58:09.620751Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-05-17T23:58:09.620751Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"d5xJ9V1wpT3NS5YbFelWJLXm0wxO35BqkitFGuiJAgidgwBK/Y89NHmVY578/uy1hTiBphPQLJLBIBq6KNM+Ag==","signature_status":"signed_v1","signed_at":"2026-05-17T23:58:09.621345Z","signed_message":"canonical_sha256_bytes"},"source_id":"1812.06655","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:6bd61747a2c2c6b7eadd7f116ac131bf7d3527220fa1f69d35fbe945fc9399c2","sha256:d52be43b27b71226b65f2dfe1f67d15835f63f7e419e3fc4f79b86711d0bc5f5"],"state_sha256":"b7e9f41fb1b6fdf48ffab99ef9f524663b0110e55a73e4b426047e920216413a"}
