Oregon State University Researchers Develop Continuous Flow Microreactor for Making Absorbers for Thin Film Solar Cells

Engineers from Oregon State University and Yeungnam University in Korea have written an article appearing in Current Applied Physics, about a system that performs chemical bath deposition to produce absorbers for thin film solar cells. Chemical bath deposition was actually developed more than a hundred years ago, but it was difficult to control the thickness, and the depletion of reactants also limits the achievable thickness.

The OSU engineers invented a continuous flow microreactor to deposit “nanostructure films” on surfaces. This technology reportedly addresses some of the issues with chemical bath deposition, and the engineers expect that eventually the process may be more commercially viable.
