Gallium doping and solar cell degradation
German scientists have conducted a series of experiments on gallium-doped silicon solar cells to understand the causes of degradation in PV cells and modules treated with gallium rather than boron. They confirmed that the performance losses are caused by a bulk defect in the material, and found that the right combination of light and temperature can “heal” earlier damage and even lead to small improvements in overall cell efficiency.
Longi sets TOPCon cell record of 25.09%
The world’s number one solar manufacturer said the result has been confirmed by the Institute for Solar Energy Research in Hamelin, Germany.
Jinko claims 24.79% efficiency for n-type monocrystalline cell
The Chinese manufacturer has claimed a world record for a large-size, contact-passivated solar cell. The result, certified by Germany’s Institute for Solar Energy Research in Hamelin, betters the company’s previous record by almost 0.6%.
