Researchers from the California Institute of Technology have a multijunction-solar cell developed on paper, an efficiency of more than 50 percent would need to pick up. The current record stands in the name of Sharp with an efficiency of 43.5 percent.
To achieve this high conversion efficiency, researchers have concentrated on the tuning of the crystal structures of the three individual photovoltaic layers, and the flow of the three layers to generate. These two properties are a major barrier revealed in the increase of the efficiency of solar cells.
The research team, composed of researchers from the California Institute of Technology in Pasadena, the National Institute of Standards and Technology in Gaithersburg and the Boeing-Spectrolab in Sylmar, the stacked solar cell consists of three composite halfgeleiderlagen, subsequently, InAlAs, State, and InGaAs.
Simulations were researchers with this design, solar cell efficiency to achieving 51.8 percent, but a prototype based on an InP-substrate is brought in long after, not yet. The current efficiëntierecord for multijunction solar cells is in the name of Sharp. Researchers at that company created a solar cell with an efficiency of 43.5 percent.
