The research team found that sodium, contrary to common belief, does not decrease per se indium and gallium interdiffusion, while instead hindering intergrain diffusion by segregating at grain boundaries.A research group from the University of Luxembourg has conducted a study that is said to change 20-year old assumptions on the chemical processes of solar cell manufacturing. According to the scientists, the addition of sodium to the light absorbing layer of the cell, which according to common belief is responsible for inhibiting the mixing of gallium and indium, may be realized through a different ...Den vollständigen Artikel lesen ...
