“…4) Further improvement of the efficiency is expected by utilizing the GaInAsP bottom cell, which has an optimum E g of about 0.95 eV as the bottom cell for the GaAs-based top cell under 1-sun air-mass 1.5 global (AM1.5G) conditions. 5) However, the performance of the GaInAsP bottom cell that we had previously fabricated was inferior to that of the GaInAs bottom cell. 4) Moreover, the highest efficiency of the GaInAsP (E g ¼ 0:95 eV) single-junction cell under 1-sun AM1.5G conditions is 11.2% to our best knowledge, 5) although a theoretical limit efficiency is about 23%.…”

“…3) It was proven that the performance of the GaInAsP bottom cell is superior to that of a GaInAs bottom cell, which agrees well with the theoretical calculation. 5) As a result, a total efficiency of 31.1% was obtained for the GaAs/GaInAsP mechanically stacked tandem cell. To our best knowledge, this is the highest efficiency obtained among the dualjunction solar cells ever reported.…”

We successfully fabricated high-performance GaAs and GaInAsP (band gap = 0.95 eV) single-junction solar cells with an area of 1×1 cm2. The conversion efficiencies of the GaAs and GaInAsP cells were 25.0 and 19.3%, respectively, under 1-sun air-mass 1.5 global (AM1.5G) conditions. The GaInAsP cell as the bottom cell under the mechanically stacked GaAs top cell also showed a high efficiency of 6.1%, and a total efficiency of 31.1% was achieved for the GaAs/GaInAsP tandem cell. This is the highest efficiency obtained under 1-sun AM1.5G conditions among the dual-junction cells ever reported.

“…3 The 9.4% result is the highest reported efficiency of any solar cell under the GaAs-filtered direct spectrum. GaInAs cells at 0.74 eV have been developed for operation either directly under a GaAs filter or under an InP filter, 3,8 and lower bandgap lattice-mismatched GaInAs cells have been developed for thermophotovoltaic applications. 9 A GaInAsP/GaInAs tandem solar cell for operation under GaAs has never been reported.…”

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.

“…Initial research on the device was devoted to the development of three-terminal tandem cells for the purpose of studying the top (InP) and bottom (Ga,,In,,,As) subcells independently, and to circumvent the problem of electrically interconnecting the subcells within the the monolithic structure. Using the three-terminal approach, the tandem cell performance progressed rapidly (2)(3)(4)(5)(6). ,and improvements in the epitaxial growth and device processing procedures eventually led to a terrestrial concentrator tandem cell efficiency of 31.8% (4,6), which is the highest value yet attained for a monolithic solar cell.…”
