Light Emission and Colored Photovoltaics
The growing market of building integrated photovoltaics (BIPVs) establishes the need for aesthetic solar modules. Our team researches colorization methods for excellent control of color impression, brightness and pattern, but also angle invariant color perception .

Perovskite Light Emission and Lasing
As a direct bandgap semiconductor, perovskite semiconductors are well-suited not only for solar cells and light emitting devices (LEDs), but also as solution-processed optical gain material in lasers with emission in the near infrared and across the visible range. To become commercially relevant in electrically pumped laser diodes, perovskite semiconductors should demonstrate first the ability to maintain optical gain under continuous wave (CW) operation and ideally at room temperature. We collaborate with the group of Ian Howard and Uli Lemmer to investigate the potential of perovskite semiconductors as a laser gain material   .
