| Popis: | 24th European Photovoltaic Solar Energy Conference, 21-25 September 2009, Hamburg, Germany; 2221-2224 A solar cell format of 156 x 39 mm is proposed and tested for multicrystalline silicon solar cells. These so called “QuarterCells” are made from standard wafers of 156 x156 mm, but with a modified front and back metallization pattern. The rectangular format allows an interconnection of the cells with short, thin pieces of wire. This results in lower shading of active silicon area and in much lower resistive losses between the cells, such that a total gain in power output of 4.4% is expected. Simultaneously the copper needed for the interconnection of cells is reduced by more than 50%. First tests on real modules confirm the expected advantages. |
