PROGRAMME 2017



Welcome to the 8th Back Contact workshop in Freiburg



The workshop will cover the latest developments in the field of back contact (BC) solar cells and modules. Challenges on the way to the industrialisation of the BC approach and examples for a successful transfer to mass production will be in the focus of the workshop. Material issues concerning module assembly will be also discussed in detail. The workshop lunchs, the dinner and several breaks will leave enough room for an exchange of views and thoughts.
