Experimental performance analysis of the concentrated crystalline silicon solar cell-slicing cell

摘要

Concentrated photovoltaic (CPV) is raised because of the high cost of solar cells. However, the commercial solar cell is designed with 1 sun. The electrical power will not have the consistent ratio with the increase of concentration ratio. This paper proposes the slicing solar cell to connect commercial cell and CPV. And the experimental research of slicing cells with variable-controlling approach is carried out with different concentration ratio. The results show that slicing design can reduce the output current and power loss caused by series resistance, and remove the upper limit of output current caused by thin grid line. The slicing cell is more suitable for concentrated light condition than normal cell. The power difference between the slicing cell and the normal cell can reach 40 W with 4 suns. Slicing crystalline silicon solar cells have great potential in concentrated photovoltaics.
