Lisicki, the 23rd seed, became the first German woman since 1999 to reach a Grand Slam final when she defeated Polish fourth seed, Agnieszka Radwanska, 6-4 2-6 9-7.
French 15th seed Bartoli, meanwhile, eased into her second Wimbledon final with a 6-1 6-2 demolition of Belgium's Kirsten Flipkens.
Lisicki, dubbed 'Doris Becker' for her howitzer serving by a tabloid British press in honour of her compatriot Boris Becker, will on Saturday bid to become Germany's first champion at a major since Steffi Graf beat Martina Hingis to claim the 1999 French Open.
Saturday's final will be only the 15th time in the Open Era to feature two players seeking their first Grand Slam title.
