Diffractive Optical Beam Splitters for Laser Multi-Beam Processing

Background: What is a diffractive beam splitter? Diffractive beam splitters, or multi-spot elements, are a family of diffractive optical elements (DOEs) that split an incoming laser beam into an array of beams with controlled separation angles. This splitting can be along a line (1-D splitters) or into a matrix (2-D splitter), including square, hexagonal or rectangular array … Continue reading

Investigating the Dynamics of Charge Transfer in Solar Cells

Tandem organic solar cells have drawn much attention in the field of solar energy. They consist of two monolithically connected cells enabling a broader absorption spectrum and efficient use of photon energy. In a Nature Communications article, entitled “High performance tandem organic solar cells via a strongly infrared-absorbing narrow bandgap acceptor,” researchers use the ultrafast … Continue reading
