prof. Tomáš Markvart, Ph.D.

Dissertation is focused on photonic structures and photon management that will be used to enhance the capture of sunlight. To this end, advanced forms of flourescent collectors will be developed with the use of frequency management in molecular complexes, applying ideas from photosyntethic light harvesting. With the help of photonics, the resulting structures will efficiently trap and guide both the incident and emitted light. The aim is to separate light capture from charge separation in a device where photonics serves as a tool to attaining high-efficiency at low cost, in a compact next-generation solar cell.

The project focuses on photonic structures and photon management that will be used to enhance the capture of sunlight. Several approaches are available that can be pursued. Based on advanced forms of fluorescent collectors, photonic frequency management can be used to both concentrate and enhance the capture of sunlight. Applying ideas from photosyntethic light harvesting, energy can be transferred to semiconductors such a silicon from molecular structures on surface to sensitise photocurrent in very thin silicon layers. The aim is to separate light capture from charge separation in a device where photonics serves as a tool to attaining high-efficiency at low cost, in a compact next-generation solar cell.
