Martin Krejci

Prof. Dr. Martin Krejci serves as Professor and Head of the Physics group at the Institute of Mathematics and Natural Sciences within FHNW's School of Engineering and Environment. With industry experience at II-VI Laser Enterprise AG and academic credentials from ETH Zurich, he leads research in semiconductor technologies while teaching courses in thermodynamics, electromagnetism, acoustics, and experimental physics for engineering students.

Krejci's research integrates fundamental physics with industrial applications in:

• High-power laser diode development
• Thin-film photovoltaic systems
• Semiconductor reliability engineering
• Accelerated life testing methodologies
• Multiphysics modeling of optoelectronic devices

His publications (1997-2013) represent two research phases:

• Early career: Thin-film solar cell innovations including flexible CIGS technology and heteroepitaxial growth (1997-1999)
• Industry-academia transition: High-power laser development addressing thermal management, reliability, and miniaturization (2009-2013)

Work consistently focuses on materials physics, structural characterization, and performance optimization of semiconductor devices.

Krejci coordinates the Physics Laboratory for Energy and Environmental Engineers, overseeing experimental training and applied research projects. His industry collaborations bridge academic research with commercial applications in photonics and renewable energy.
