Data Science Intern – Device Characterization (Spring 2027)

Cagayan State University; Perrysburg (OH); On-site; USD 30,000 - 34,000; Full time

Benefits offered by this job

Hourly compensation: $22-$25

Job summary

Cagayan State University is offering an internship focused on building data pipelines to automate perovskite device characterization. You will work with an engineer mentor to extract key IV metrics from raw data and classify anomalies using Python-based analysis tools.

Extend the pipeline to image-based metrics, develop go/no-go criteria, and prepare a leadership presentation summarizing outcomes and learnings from the project.

Qualifications

• Pursuing Bachelor's or Master's in Physics, EE, MSE, or Data Science.
• Proficiency in Python for data analysis (pandas, numpy, scipy, matplotlib).
• Knowledge of solar cell J-V characteristics and EL/PL for device characterization.
• Experience with image analysis, curve fitting, anomaly detection, or basic ML.
• Understanding PV device physics and common J-V anomalies (hysteresis, S-kink, shunting).
• Strong documentation and communication skills.

Responsibilities

• Build data pipelines to automate device characterization for perovskite panels.
• Collaborate with an engineer mentor using historical IV data, image libraries, and computing resources.
• Develop a Python pipeline to auto-extract Voc, Jsc, FF, PCE, Rs, and Rsh from raw J-V files and classify anomalies.
• Deliver the pipeline along with an automated pass/fail report template.
• Extend the pipeline to assess EL images and correlate image metrics with IV metrics.
• Establish go/no-go screening criteria to standardize anomaly classification and reduce losses.
• Present accomplishments and project summary to leadership on internship completion.

Job description

Your Role

Here's what you will be doing:

• Build data pipelines to automate device characterization for perovskite panels.
• Work alongside an engineer mentor using historical IV data, image/performance libraries, and computing resources.
• Develop a Python pipeline (Months 1-3) to auto-extract Voc, Jsc, FF, PCE, Rs, and Rsh from raw J-V files and classify anomalies such as hysteresis, S-kink, shunting, and poor fill factor.
• Deliver the pipeline along with an automated pass/fail report template.
• Extend the pipeline (Months 4-6) to assess YS300 EL images and correlate image-derived metrics with reverse-scan IV metrics.
• Establish go/no-go screening criteria for panels entering finishing to standardize anomaly classification and reduce BOM losses.
• Present accomplishments and project summary to the leadership team upon internship completion.

About You

The company is looking for candidates with:

• Current pursuit of 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, including pandas, numpy, scipy, and matplotlib.
• Working knowledge of solar cell J-V characteristics (Voc, Jsc, FF, PCE, Rs, Rsh), photoluminescence (PL) or electroluminescence (EL) for semiconductor device characterization.
• Experience with image analysis, curve-fitting, anomaly-detection methods, or basic machine learning.
• Understanding of PV device physics and common J-V curve anomalies such as hysteresis, S-kink, and shunting.
• Basic image-analysis or statistical-correlation techniques.
• Strong documentation and communication skills to collaborate effectively with an engineer mentor.

Compensation & Benefits

• Estimated salary range: $22-$25 per hour.
