17.8% Efficiency Obtained on c-Si Solar Cells Using a Selective Emitter Industrial Type Process
Year: 2008
Type: article
Abstract: The formation of selective emitters is a key issue to achieve higher efficiencies on industrial screen printed silicon solar cells. A study on the development of selective emitter concepts is presented using POCl3 diffusion for the development of the high and low doped emitters. The work is focused on the application of the developed technology to an industrial level, considering the alignment requirements between the highly doped emitter pattern and the front silver grid. Our selective emitter process shows a great efficiency improvement of 0.5% absolute which is related to an improved spectral response in the short wavelength range. Efficiencies of 16.6% are obtained on 150 mm x 150 mm mc-Si cells and 17.8% on 125 mm x 125 mm c-Si cells.
