关于这个数据集
为什么 PV-Atlas KG 与众不同
① 证据 span 级溯源
每条三元组都带来源文献的字符级 span,可一键定位到原文段落, 不像普通知识图谱"知其然不知其所以然"。
② 冲突仲裁透明
同一关系出现多源冲突时,记录"谁覆盖了谁、原因是什么", 由 CQA 保守仲裁裁定,保留 lineage 全程可追溯。
③ 4-lens ontology
把光伏实体按对象 / 过程 / 属性 / 事件四视角分类, 覆盖材料、工艺、性能、故障全链,论文 §4 详述。
④ 按月演进
版本号用发布日期,每月迭代。提供 一键更新脚本,旧版本无需手工 diff。

PID
→ detectedBy →
EL_imaging
"Potential-induced degradation (PID) appears in EL images as a characteristic darkening near the cell's grounded edge."
HJT_cell
→ characterizedBy →
open_circuit_voltage_745mV
"Industrial HJT cells now routinely exceed 745 mV Voc at standard test conditions on M10 wafers."
microcrack_propagation
→ testedBy →
mechanical_load_test_5400Pa
"Module-level microcrack propagation is screened by 5400 Pa front-side mechanical load cycling per IEC 61215 MQT-16."
SOP-PID-RECOVERY-V2
→ respondsTo →
PID_fault
"PID recovery procedure (SOP-PID-RECOVERY-V2): reverse-bias the affected string at +500 V relative to ground for 16 hours; re-measure EL after 48 h."

下载格式
3 种发布形态,按需取用
SQLite 一站式 .db
atlas.db — 实体、三元组、provenance、conflict_lineage 全在一个文件,复现性最好。
JSONL(实体 / 三元组)
entities.jsonl + triples.jsonl,便于 Python / Spark 直接 stream 处理。
Neo4j 图数据库 dump
neo4j_dump.cypher.gz + docker-compose,开箱即用图查询。
