技术深度｜EL+PL 双模成像，精准剖析钙钛矿微观缺陷
钙钛矿电池凭借高效、低成本、可柔性制备等优势，成为光伏领域的核心发展方向。但其薄膜均匀性、晶界缺陷、针孔、界面复合、组分偏析等微观问题，严重制约效率、稳定性与寿命。传统检测仅能观察表面，无法捕捉内部隐性缺陷，难以支撑工艺迭代与性能突破。
Perovskite solar cells, with high efficiency, low cost and flexible fabrication, have become a core development direction in photovoltaics. However, micro issues such as film uniformity, grain boundary defects, pinholes, interface recombination and composition segregation severely limit efficiency, stability and lifespan. Traditional inspection only observes the surface, failing to capture hidden internal defects and support process iteration and performance breakthroughs.
曜华激光 YHG‑ELPL 钙钛矿电池 EL+PL 测试仪，集成电致发光（EL）与光致发光（PL）双模成像技术，实现工作态缺陷 + 材料本征缺陷双维度同步检测，一次成像即可完成全面缺陷诊断。
Yohasolar Laser’s YHG‑ELPL Perovskite EL+PL Tester integrates Electroluminescence (EL) and Photoluminescence (PL) dual‑mode imaging, enabling simultaneous inspection of operational defects and material‑intrinsic defects, completing comprehensive defect diagnosis in one shot.
EL（电致发光）：正向恒流激发电子 - 空穴复合发光，缺陷区呈暗区，直观呈现电流分布不均、隐裂、黑片、接触不良、串联电阻异常等工作态缺陷，真实反映电池运行状态。
EL (Electroluminescence): Forward constant current stimulates electron‑hole recombination emission. Defective areas appear dark, directly showing operational defects such as uneven current distribution, microcracks, dark spots, poor contact and abnormal series resistance, truly reflecting cell operation status.
PL（光致发光）：450/915/980nm 激光激发，捕捉材料本征发光信号，精准识别晶界、晶粒不均、针孔、组分偏析、非辐射复合中心等材料本征缺陷，评估薄膜质量与载流子寿命。
PL (Photoluminescence): Excited by 450/915/980nm laser, it captures intrinsic emission signals, accurately identifying material‑intrinsic defects such as grain boundaries, grain inhomogeneity, pinholes, composition segregation and non‑radiative recombination centers, evaluating film quality and carrier lifetime.
双模数据互补、结果相互验证，助力科研团队解析缺陷成因、优化材料配方、迭代制备工艺；赋能企业快速稳定量产一致性、缩短研发周期、降低试错成本，为钙钛矿电池从实验室到量产提供全流程技术支撑。
Complementary dual‑mode data and mutually verified results help research teams analyze defect causes, optimize material formulas and iterate fabrication processes; enabling enterprises to quickly stabilize production consistency, shorten R&D cycles and reduce trial‑and‑error costs, providing full‑process technical support for perovskite cells from lab to mass production.
