One of these is interdigitated back contact (IBC) solar cell (Fig. 1 a). Contacts of IBC cells for both polarities are placed at the rear side to avoid front metal grid shading. As a result, short-circuit current density (J sc) of over 41 mA/cm 2 is expected.
Image: International Solar Energy Research Center (ISC) Konstanz Researchers from German research center ISC Konstanz and the Delft University of Technology (TU Delft) in the Netherlands have fabricated an interdigitated back contact (IBC) solar cell with a new patterning technique for structuring the rear side of the device.
The fill factor of the test cell is measured to be 78.6%, demonstrating a working tunnel junction at the device level. The tunnel resistivity of the tunnel junction needs to be further reduced to improve the fill factor and hence the efficiency of the targeted IBC solar cell.
Interdigitated back contact (IBC) solar cells featuring passivated contacts are promising candidates to achieve record-efficiency single-junction silicon-based solar cells. However, they usually require processes that are not amenable for industrial mass production and involve great process complexity associated with patterning and alignment.
Conventional high-temperature fire-through screen printing for both polarities. Efficiency potential over 26%. Interdigitated back contact (IBC) solar cells featuring passivated contacts are promising candidates to achieve record-efficiency single-junction silicon-based solar cells.
The results indicate that with an optimal geometry and engineered bandgap grading, the efficiency of the new IBC structure can reach 17%. Additionally, with a reasonably low defect density in the absorber layer, efficiencies as high as 19.7% and open-circuit voltage comparable with that of the record solar cell are possible with the IBC structure.
In the targeted IBC solar cell, there will be no poly-Si layer at the front side hence parasitic absorption can be avoided. Download: Download high-res image (262KB) Download: …
