Metrology for the photovoltaics industry - Energy - Solar Power
Quality control to maximize efficiency is critical in the competitive photovoltaic industry. For some time solar texture has been thought to qualitatively affect solar cell efficiency. However, through large-area, 3D measurements and areal feature parameters, quantitative correlation of texture to efficiency has only recently been obtained. We now know that ISO 3D surface parameters linearly correlate with solar cell efficiency.

Bruker’s 3D microscopes provide the subnanometer vertical resolution over large fields of view necessary for this correlation, and can measure rapidly at junctions or other critical areas to more fully characterize the lines and better control the properties of the solar cell. In addition, Bruker’s stylus profilers offer a rapid check of linewidth and height over one or more sections of the sample.
