Seeing the big picture in photosynthetic light harvesting: Berkeley Lab researchers create first multiple antennae model of photosystem II

The new model simulates light-harvesting across several hundred nanometers of a thylakoid membrane, which is the membrane within a chloroplast that harbors photosystem II (PSII), a complex of antennae made up of mostly of chlorophyll-containing...

Cheaper solar cells with 20.2 percent efficiency

Some of the most promising solar cells today use light-harvesting films made from perovskites - a group of materials that share a characteristic molecular structure. However, perovskite-based solar cells use expensive "hole-transporting" materials,...
