University of California – Santa Barbara researchers have uncovered a major cause of limitations to efficiency in perovskite solar cells. Various possible defects in the lattice of what are known as hybrid perovskites had previously been considered as the potential cause of such limitations, but it was assumed that the organic molecules (the components responsible […]

Now Holograms Make Improved Solar Panels
May 26, 2021 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Arizona researchers recently developed an innovative technique to capture the unused solar energy that illuminates a solar panel. The team created special holograms that can be easily inserted into the solar panel package. Each hologram separates the colors of sunlight and directs them to the solar cells within the solar panel. This […]

2D Perovskites May Make Better LEDs and Solar Cells
April 15, 2021 | 1 Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… University of Surrey engineers’ innovative analysis of two-dimensional (2D) materials could boost the development of next-generation solar cells and LEDs. Three-dimensional perovskites have proved themselves remarkably successful materials for LED devices and solar panels in the past decade. One key issue with these materials, however, is their stability, with device performance decreasing quicker than […]

Will You Need To Invest In Solar Panels?
March 16, 2021 | 2 Comments
Consumers and utility companies have worried for years that solar panels drive up electricity costs for the people who don’t have panels. But Michigan Technological University renewable energy researchers show the opposite is actually true – grid-tied solar photovoltaic (PV) owners are actually subsidizing their non-PV neighbors. Beyond the environmental benefits and lower electric bills, […]

Tandem Perovskite Silicon Solar Cells Up To 30% Efficiency
February 3, 2021 | Leave a Comment
Open Image…Save ImageOpen Image (using #TmpD/ia)… Helmholtz-Zentrum Berlin für Materialien und Energie (HZB) scientists have set the current world record of 29.15% efficiency for a tandem solar cell made of perovskite and silicon. The tandem cell provided stable performance for 300 hours – even without encapsulation. To accomplish this, the group investigated physical processes at the interfaces to improve the […]
