We describe the design and performance of a three-terminal tandem solar cell for low-concentration terrestrial applications. Designed for operation under a GaAs filter, the tandem demonstrates cumulative conversion efficiencies of 10.2 and 11.9% at 1 sun and 45 suns, respectively, under the concentrated direct spectrum. The middle terminal is shared between the two subcells and allows them to be operated independently at their respective maximum power points. Copyright # 2009 John Wiley & Sons, Ltd.read more

Nanoscale Back Contact Perovskite Solar Cell Design for Improved Tandem Efficiency
TL;DR: This work introduces a novel architecture based on a nanoscale back-contact for a thin-film top cell in a three terminal (3-T) configuration using coupled optical–electrical modeling, and optimize this architecture for a planar perovskite-silicon tandem, highlighting the roles ofnanoscale contacts to reduce the required perovSKite electronic quality.

TL;DR: In this article, the authors investigate the operation of three terminal tandems in detail using technology computer aided design (TCAD) device physics simulations, and show how the addition of a third terminal can deliver comparable power output to a four terminal device, and substantially more power than a two-terminal device, while also enabling power injection and extraction between the two sub-circuits under a variety of spectral conditions.
