With its newest solar cell, the Fraunhofer Institute for Solar Energy Systems ISE has now exceeded its own world record for multicrystalline solar cells.
Although perovskite solar cells have only been developed within the past few years, they are already almost as energy-efficient as silicon.
Using the compound eye as a model, the researchers created a compound solar cell consisting of a vast honeycomb of perovskite microcells, each encapsulated in a hexagon-shaped scaffold just 0.02 inches (500 microns) wide.
The research groups created tandem solar cells with record efficiencies of converting sunlight into electricity under 1-sun illumination.
A concentrating photovoltaic system with embedded microtracking can produce over 50 percent more energy per day than standard silicon solar cells in a head-to-head competition, according to a team of engineers who field tested a prototype unit over two sunny days last fall.
Scientists at the U.S. Department of Energy’s Ames Laboratory, believes improvements in solar cells, computer processors, and TV displays will come from scientific advancements in the synthesis of low-dimensional nanomaterials.
