In this work, we analyze the potential of increasing the bandgap using AlGaAs to minimize the energy difference. The optimum aluminum content is 7 % in both single and triple junction converters reaching a maximum ideal efficiency of 71% at 1 W/cm2 and 77% at 50 W/cm2.","authors_text":"Carlos Algora, Iv\\'an Garc\\'ia, Marina Delgado","cross_cats":[],"headline":"","license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"physics.app-ph","submitted_at":"2021-12-28T12:24:40Z","title":"Design of AlGaAs Laser Power Converters for the First Transmission Window"},"references":{"count":0,"internal_anchors":0,"resolved_work":0,"sample":[],"snapshot_sha256":"258153158e38e3291e3d48162225fcdb2d5a3ed65a07baac614ab91432fd4f57"},"source":{"id":"2112.14110","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:c6b0ca6b0f23b1050cc776efacd521c4cb03d27aeedfb3a77ae87353a81d7825","target":"record","created_at":"2026-07-05T03:44:18Z","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":"7b8cc894c03708889114492faccb7f16d066cf76310709239c15331f41f4f175","cross_cats_sorted":[],"license":"http://creativecommons.org/licenses/by-nc-nd/4.0/","primary_cat":"physics.app-ph","submitted_at":"2021-12-28T12:24:40Z","title_canon_sha256":"0fc73c33c2f1b9977258f71157fe3b6dbd823e622859f775ca6a8b1e34fb0baa"},"schema_version":"1.0","source":{"id":"2112.14110","kind":"arxiv","version":1}},"canonical_sha256":"4dd9a02a88538d2415925a9773f0b0172998d83b1147162d3f0e4e79537c903f","receipt":{"algorithm":"ed25519","builder_version":"pith-number-builder-2026-05-17-v1","canonical_sha256":"4dd9a02a88538d2415925a9773f0b0172998d83b1147162d3f0e4e79537c903f","first_computed_at":"2026-07-05T03:44:18.641937Z","key_id":"pith-v1-2026-05","kind":"pith_receipt","last_reissued_at":"2026-07-05T03:44:18.641937Z","public_key_fingerprint":"8d4b5ee74e4693bcd1df2446408b0d54","receipt_version":"0.3","signature_b64":"Clk0JZFkrb4A5iXYuugw6Ou/EyEXBuvnTFo/yt+tMbs3Ci/aonRbswxf6FsOlZ6kZ5+ODOorZfv22S5md46dAA==","signature_status":"signed_v1","signed_at":"2026-07-05T03:44:18.642394Z","signed_message":"canonical_sha256_bytes"},"source_id":"2112.14110","source_kind":"arxiv","source_version":1}}},"equivocations":[],"invalid_events":[],"applied_event_ids":["sha256:c6b0ca6b0f23b1050cc776efacd521c4cb03d27aeedfb3a77ae87353a81d7825","sha256:1874cb3d501593db8e01df26682de9d66618ea299b3a9b3ba607695b0783d24f"],"state_sha256":"d01c9d34a87e9ce3b33ef2725ee5351f93854c6d626341cd2861b8fac132feb6"}
