The young Doctor Franck Dimroth is working in the Fraunhofer Institute for Solar Energy Systems in Freiburg, in Germany.
With his team, he has developed a metamorphic triple-junction solar cell : it can convert more sunlight to electricity than many other solar cells, reaching a record efficiency of 41.1%. To accomplish this, researchers created a multi-junction solar cell made of III-V compound semiconductors by stacking three single-junction cells on top of each other, each one particularly efficient in converting a limited spectral bandwidth of sunlight to electricity. The result : efficiency levels that nearly double the efficiency of conventional silicon-based solar cells.
The Fondation Louis D was established 10 years ago under the auspices of the Institut de France. The foundation presents a major science award each year, along with a major award for research in the humanitarian or cultural area.
