Tandem devices are well known to surpass single junctions. However, the limitations of current-matching is a concern for changing spectra in terrestrial applications. Three terminal tandem (3T) devices can be more robust to these variations resulting in higher energy yield than single junction devices and two terminal series-connected tandems. We fabricate one-sun 3T tandem devices made of inverted grown III-V tandem (GaInP/GaAs) as a prototype of 3T tandems for stringing and measurement demonstrations. We demonstrate 3T tandem measurements that can be used to understand the use of 3T tandems in various constrained configurations.
