Poly-Si(O)x passivating contacts for high-efficiency c-Si IBC solar cells
Abstract
<p>Highest conversion efficiency in crystalline silicon (c-Si) solar cells can be enabled by quenching minority carriers' recombination at c-Si/contact interface owing to carrier-selective passivating contacts. With the semi-insulating poly-crystalline silicon (SIPOS, poly-Si) a very good passivation of c-Si surfaces was obtained. We have explored these passivating structures on IBC solar cells and obtained over 22% efficiency with over 23% within reach on the short term. We present in detail the passivation quality of p-type and n-type ion-implanted LPCVD poly-crystalline silicon (poly-Si) and its relation to the doping profile. Optimized poly-Si layers in the role of emitter and BSF showed excellent passivation (J<sub>0,emitter</sub> = 11.5 fA/cm<sup>2</sup> and J<sub>0,BSF</sub> = 4.5 fA/cm<sup>2</sup>) and have been deployed in FSF-based IBC c-Si solar cells using a simple self-aligned patterning process. Applying an optimized passivation of FSF by PECVD a-Si:H/SiNx layer (J<sub>0,FSF</sub> = 6.5 fA/cm<sup>2</sup>) leads to a cell with efficiency of 22.1% (V<sub>OC</sub> = 709 mV, J<sub>SC</sub> = 40.7 mA/cm<sup>2</sup>, FF = 76.6%). Since over 83% FF has been reached with adjusted metallization technology on similar IBC structures, we believe 23% efficiency is within reach on the short term. Further improvement, especially at J<sub>SC</sub> level, is expected by deploying less absorbing carrier-selective passivating contacts based on poly-Si or wide bandgap poly-SiO<sub>x</sub> layers (J<sub>0</sub> ~ 10 fA/cm<sup>2</sup>).</p>
