WitrynaAbout this book. In the last 7 years, the ?rst edition of “Lock-in Thermography” has established as a reference book for all users of this technique for investigating … Witrynalock-in thermography produce complementary information: LBIC reveals the defects degrading the short circuit current, and thermography reveals the defects degrading the open circuit voltage and the fill factor of the cells. Thus, lock-in thermography is a valuable tool for optimizing the efficiency of solar cells by avoiding shunting activities.
