A hybrid photovoltaic/photoelectrochemical (PV/PEC) water-splitting device with a benchmark solar-to-hydrogen conversion efficiency of 5.2% under simulated air mass (AM) 1.5 illumination is reported. This cell consists of a gradient-doped tungsten-bismuth vanadate (W:BiVO4 ) photoanode and a thin-film silicon solar cell. The improvement with respect to an earlier cell that also used gradient-do...
Summary Multijunction solar cell design is guided by both the theoretical optimal bandgap combination as well realistic limitations to materials with these bandgaps. For instance, triple-junction III-V multijunction cells commonly use GaAs a middle because of its near-perfect material quality, despite being higher than for global spectrum. Here, we modify using thick GaInAs/GaAsP strai...
Colloidal quantum dot solids combine convenient solution-processing with quantum size effect tuning, offering avenues to high-efficiency multijunction cells based on a single materials synthesis and processing platform. The highest-performing colloidal quantum dot rectifying devices reported to date have relied on a junction between a quantum-tuned absorber and a bulk material (e.g., TiO(2)); h...
DOI: 10.1002/aenm.201700345 conversion efficiency. Devices comprising these alloys (and, in some cases, the group IV element, germanium) have held the world record for conversion efficiency under concentrated sunlight for more than the last thirty years with steady increases in efficiency year-on-year.[2] Efficiency improvements result from many aspects of MJSC design, but among the most import...
Optical coupling from InGaAs subcell to InGaP subcell in InGaP/InGaAs/Ge multi-junction solar cells.
Spatially-resolved electroluminescence (EL) images in the triple-junction InGaP/InGaAs/Ge solar cell have been investigated to demonstrate the subcell coupling effect. Upon irradiating the infrared light with an energy below bandgap of the active layer in the top subcell, but above that in the middle subcell, the EL of the top subcell quenches. By analysis of EL intensity as a function of irrad...
