A New Way to Image Solar Cells in 3-D

Scientific Achievement

A team of Molecular Foundry scientists and users have developed a way to use optical microscopy to map thin-film solar cells in 3-D as they absorb photons.

Significance and Impact

The method images optoelectronic dynamics in materials at the micron scale to see individual grain boundaries, substrate interfaces, and other internal obstacles that impacts a solar cell’s efficiency.
