SOLOMYA opens doors into the molecular world of dye-sensitized and organic solar cell. Using mass spectrometry, we investigate chemical processes in the solar cells, e.g. assembly of complex molecular structures on the electrode surface or maturation and degradation of the solar cell components. Also, we analyze conducting polymers (Mn, Mw, PDI, end-group analysis, impurities). SOLOMYA is a spin-off company based on the research that was done at Uppsala university
