ISE L-shaped tandem

This examples simulates the 1 cm x 1 cm laboratory Si-perovskite tandem solar cell design of Fraunhofer ISE, featuring an L-shaped metallization pattern. 

It uses the "generic syntax" to define a quarter-symmetry solution domain including the L-shaped metal geometry, and including a dark perimeter region to account for perimeter losses.

Details will be found in a JPV paper later this year (submitted).
