Solar energy has by far the largest potential of all renewable energy sources and photovoltaics is the key technology to utilize this potential. At present photovoltaics technology ranges from widely employed first generation silicon wafer based solar cells to third generation multijunction cells used in space. | 22

Helimagnets are magnetically ordered materials in which the spin-orbit interaction leads to a spiral structure of the magnetization. I will review the phenomenology of MnSi as the prototypical and best studied helimagnet, in particular various phases or suspected phases identified by neutron scattering and other techniques. The most spectacular feature is a pronounced T^(3/2) behavior of the resistivity in a large region of parameter space. I will then review theoretical efforts to understand the observed effects. | 24
