Physics of Solar Cells

Wintersemester 2019/20 — Winter term 2019/20

Master Physik Modul 741a, 732, PHY731m, PHY741a • Master Polymer Science 2nd year • Bachelor Physik Modul 541a

On a sunny day, the power introduced to the earth by the sun reaches up to 1 kW/m2 on the earth's surface. Thus, the conversion of sunlight into electric power using solar cells is a highly topical field of physical research.

This lecture will discuss the physical processes in solar cells as well as recent developments in the field. Topics covered will include

  • the solar radiation field
  • physical limits to solar thermal energy conversion
  • electrons and holes in semiconductors
  • classic silicon solar cells
  • physical limitations on energy conversion in solar cells (Shockley-Queisser limit)
  • new concepts for efficient solar cells (tandem cells, thin film devices)
  • organic and hybrid devices

Lecture: Martin Stolterfoht/Safa Shoai/Dieter Neher

Monday • 17:00-18:30 •

Exercises: Lorena Perdigón Toro
