我们研究了碳共掺杂对直拉法生长的掺硼硅太阳电池性能的影响。研究发现，碳共掺杂对氧沉淀的形成有促进作用，在光致退化(LID)之前，碳掺杂会使铝背电场太阳电池的初始性能变差。但是，碳共掺杂可以有效地抑制B-O络合物在太阳电池中的形成，并且随着碳浓度的增加，抑制作用更加明显。因此，碳共掺杂硅太阳电池的性能优于盖板后的常规硅太阳电池。这些结果对低盖效应碳共掺硅太阳电池在光伏产业中的实际应用具有重要意义。
We have investigated the impact of carbon co-doping on the performance of boron–doped Czochralski-grown silicon solar cells. It is found that carbon co-doping will deteriorate the initial performance of Aluminium-back-surface-field solar cells before light-induced degradation (LID), owing to the enhancement effect on the formation of oxygen precipitation. However, carbon co-doping can effectively suppress the formation of boron-oxygen complexes in the solar cells, which becomes more significant with an increase of the carbon concentration. Therefore, the performance of carbon co-doped silicon solar cells is better than that of conventional silicon solar cells after LID. All these results are of great significance for the practical application of carbon co-doped silicon solar cells with low LID effect in photovoltaic industry.
