Hauptseminar: Green Energy Seminar – Overview
Seminar: Solar Cells to Solar Fuels - from basics to applications (Master/Diploma)
About the lecture
Time and placeWednesdays 14:45 - 16:15 pm CET, Nano-Institute Munich (Königinstr. 10), Conference room, 1st floor (street entrance level)
Rising atmospheric levels of carbon dioxide and the depletion of fossil fuel reserves raise serious concerns about the ensuing effects on the global climate and future energy supply. Utilizing the abundant solar energy to produce electricity or to drive artificial photosynthetic reaction to convert water and carbon dioxide into fuels are potential solutions to both energy harvesting and storage. The Seminar will cover five main topics. Firstly, the current status of the research in batteries will be discussed, together with the role of the batteries in balancing the electricity grid and the impact on the grid architecture. The second part will cover solar cells: architecture, light harvesting, charge separation, efficiency limitations, new materials and methods to overcome the Shockley-Queisser limit.
The third part will cover efficient light emission based on inorganic and organic nanoparticles. The fourth part will focus on the passive radiative cooling to eliminate the need for energy consuming current air conditioning approaches. The last, extensive, part will cover natural photosynthesis, in particular light harvesting and charge transport. The fourth part will focus on heterogeneous solar fuel generation with nanocrystalline semiconductor particles, starting from thermodynamic and kinetic aspects of photocatalysis, through photosensitization to semiconductor-based photocatalysts for hydrogen generation via water reduction, full water splitting and carbon dioxide reduction. The architecture, limitations and figures of merit for photocatalytic and photoelectrocatalytic systems will also be discussed.
The seminar addresses in particular master students which have followed the lecture Advanced Solid State Physics (EM1) or Optoelectronics, but is not exclusively for these students.

Students are encouraged to provide a list of preferred topics for their presentation. By default, there will be 2 talks per seminar. If more than 24 students enrol for the seminar, additional topic will be proposed and selected seminars will have 3 talks.
The introductory first seminar will be on 24 April 2019 and it will be a chance to sign in for the seminar. Anyone who cannot attend this first seminar, please write an email to Jacek Stolarczyk.
The seminar will be credited if:
(a) a presentation is given,
(b) all presentations (missing 3 at most) have been attended,
(c) the student actively participated in discussions
