Job Summary

The Postdoctoral Research Associate in Organic Electronic Devices and Organic Solar Cells (Gu Group) conducts research focused on organic electronic device fabrication, particularly organic solar cells, performance testing, and operational stability. This position investigates how materials, processing methods, device architecture, and encapsulation affect photovoltaic performance and degradation under light, heat, and environmental exposure. The position coordinates research and laboratory activities, analyzes and interprets data, communicates research findings to sponsors and collaborators, and prepares publications and presentations. The Postdoctoral Research Associate also assists faculty with sponsored project management and reporting and provides research guidance to graduate and undergraduate researchers.

Primary Job Duties and Responsibilities

• Fabricates and optimizes organic electronic devices, particularly organic solar cells. Develops reproducible procedures for substrate preparation, active-layer and interfacial-layer processing, electrode deposition, and encapsulation. Investigates the effects of processing methods and device architecture on performance.
• Characterizes device performance using current-voltage, external quantum efficiency, and complementary electrical and optical measurements. Investigates performance-limiting mechanisms, establishes testing procedures, and evaluates reproducibility across fabrication batches.
• Evaluates device stability through operational and accelerated aging studies under controlled illumination, temperature, atmosphere, and humidity. Performs maximum power point tracking, analyzes lifetime metrics, and investigates degradation mechanisms and strategies to improve stability.
• Prepares peer-reviewed publications, research proposals, presentations, technical reports, and related documentation. Maintains experimental records, analyzes and interprets research results, assists faculty with sponsored project management and reporting, and communicates project progress to collaborators and funding organizations.
• Trains and mentors graduate and undergraduate researchers in device fabrication, characterization, stability testing, laboratory safety, and data analysis. Provides guidance in establishing research priorities and developing reproducible experimental practices.
• Participates in research collaborations, project meetings, conferences, and travel to collaborating institutions, national laboratories, or sponsor locations as needed. Adheres to University and departmental policies and procedures and supports safe laboratory operations and equipment maintenance.
• Performs other duties as assigned.

Minimum Qualifications

Ph.D. from an accredited college or university in Materials Science and Engineering, Polymer Science and Engineering, Chemistry, Chemical Engineering, Physics, Electrical Engineering, or a related field. Three (3) years of experience in organic electronic device fabrication and characterization. Three (3) years of experience with organic semiconductor materials, thin-film processing, and materials-device performance relationships. A peer-reviewed publication record is required.

Knowledge, Skills, and Abilities (KSA)

• Knowledge of organic semiconductor materials, device physics, thin-film processing, and photovoltaic characterization.
• Knowledge of organic electronic device fabrication, characterization, and stability testing methods.
• Knowledge of experimental research methods and laboratory safety practices.
• Ability to design and conduct controlled research experiments.
• Ability to troubleshoot device fabrication, instrumentation, and measurement processes.
• Ability to analyze and objectively evaluate device performance, reproducibility, stability, and degradation data.
• Ability to maintain accurate experimental records and research documentation.
• Ability to conduct research independently and collaborate with faculty, scientists, engineers, students, and research partners.
• Ability to prepare scientific publications, research proposals, technical reports, and presentations.
• Ability to train and provide research guidance to graduate and undergraduate researchers.
• Ability to coordinate research activities, priorities, and sponsored project requirements.
• Skill in written and verbal communication
• Skill in technical writing and scientific presentations.
• Skill in organization, problem-solving, and data analysis.
• Ability to travel to conferences, collaborating institutions, national laboratories, and sponsor locations as needed.

Preferred Qualifications

Three (3) years of experience with organic solar cells, including non-fullerene acceptors, is preferred. Three (3) years of experience with spin coating, blade coating, slot-die coating, or related solution-processing methods is preferred. Three (3) years of experience with glovebox operation, vacuum deposition, interfacial-layer engineering, encapsulation, current-voltage measurements, external quantum efficiency measurements, light-intensity-dependent measurements, or maximum power point tracking. Three (3) years of experience with operational and accelerated aging studies, International Summit on Organic Photovoltaic Stability (ISOS) protocols, and photoinduced, thermal, oxygen-related, or moisture-related degradation is preferred. Three (3) years of experience with electrical, optical, or morphological characterization methods used to evaluate relationships among materials, interfaces, device performance, and stability. Three (3) years of experience with automated data acquisition, instrument control, or performance and lifetime data analysis.
