标题： Temperature coefficient of Silicon based carrier selective solar cells

摘要： 载流子选择性（CS）硅太阳能电池正日益被探索为PN结硅太阳能电池的低成本替代品。 尽管最近在功率转换效率方面的趋势令人鼓舞，但此类太阳能电池在高温下的温度系数以及功率输出尚未得到充分研究。 在此，我们通过详细的数值模拟来解决这一问题，以探讨界面和材料参数对温度系数的影响。 我们的结果表明，无论界面质量如何，CS太阳能电池的温度系数会随着带隙不连续性的增加而改善。 有趣的是，与效率相关的趋势相反，我们的结果表明，CS太阳能电池的温度系数更受少数载流子提取层的界面质量影响，而不是多数载流子提取层。 这些见解对选择基于硅的CS太阳能电池的最佳材料和加工条件具有重要意义。 显示英文摘要

摘要： Carrier Selective (CS) Silicon solar cells are increasingly explored as a low cost alternative to PN junction Silicon solar cells. While the recent trends on power conversion efficiency are encouraging, the temperature coefficient and hence the power output under elevated temperatures are not well explored for such solar cells. Here, we address this issue through detailed numerical simulations to explore the influence of interface and material parameters on the temperature coefficient. Our results indicate that irrespective of the interface quality, the temperature coefficient of CS solar cells improves with an increase in band discontinuities. Interestingly, contrary to the trends related to efficiency, our results indicate that the temperature coefficient of CS solar cells is more critically affected by the interface quality of the minority carrier extraction layer than the majority carrier extraction layer. These insights have important implications towards the choice of optimal material and processing conditions for Si based CS solar cells.
