Responsibilities

The intern will build data pipelines that automate device characterization for perovskite panels, working alongside an engineer mentor with access to historical IV data, an image/performance library, and a workstation, internal server, or cloud compute access
Major project – Automated Device Characterization Pipeline: Months 1–3, build a Python pipeline that auto-extracts Voc, Jsc, FF, PCE, Rs, and Rsh from raw J-V files and classifies anomalies (hysteresis, S-kink, shunting, poor fill factor), delivering the pipeline plus an automated pass/fail report template. Months 4–6, extend the pipeline to assess YS300 EL images and correlate image-derived metrics with reverse-scan IV metrics, establishing go/no-go screening criteria for panels entering finishing. This standardizes anomaly classification across the team and lays the groundwork for pre-finishing panel screening that reduces BOM losses
Upon the completion of this internship, the intern is required to present their accomplishments and project summary to the leadership team

Qualification

Required

Currently pursuing a Bachelor's or Master's degree in Physics, Electrical Engineering, Materials Science, or Data Science; upper-level undergraduate (junior/senior) or graduate student
Proficiency in Python for data analysis (pandas, numpy, scipy)
Working knowledge of solar cell J-V characteristics (Voc, Jsc, FF, PCE, Rs, Rsh), photoluminescence (PL) or electroluminescence (EL) for semiconductor device characterization, image analysis, curve-fitting or anomaly-detection methods, or basic machine learning
Python data analysis (pandas, numpy, scipy, matplotlib); understanding of PV device physics and common J-V curve anomalies (hysteresis, S-kink, shunting); basic image-analysis or statistical-correlation techniques; strong documentation and communication skills to work effectively with an engineer mentor

Preferred

Benefits
