Robin Lang

Dr. Robin Lang is a Researcher at the Fraunhofer Institute for Solar Energy Systems ISE, specializing in advanced photovoltaic technologies. His work focuses on III-V multi-junction solar cells, particularly the development of wafer-bonded concentrator cells using metal-organic vapor phase epitaxy (MOVPE). In November 2024, he received the 'Best Oral Presentation Award' at PVSEC-35 in Japan for his research on improving solar cell efficiency through structural optimizations.

Research Interests:

• Development of high-efficiency multi-junction solar cells
• Wafer-bonding techniques for semiconductor integration
• Loss analysis in photovoltaic materials and manufacturing
• Advancements in III-V semiconductor technologies

Key Achievement: His team's improvements in cell structure increased voltage by 140 millivolts, bringing their cells close to world-record efficiency levels.

Awards:

• Best Oral Presentation Award at PVSEC-35 (2024)

Labs/Teams: Works within the Photovoltaics department at Fraunhofer ISE, collaborating with senior researchers like Prof. Dr. Stefan Glunz.
