摘要

本文通过二维模拟研究了高度、基底宽度和掺杂水平对双pn结隧道式硅垂直太阳能电池效率的影响。结果表明，p-n结高度的依赖效率具有非单调性。这是由于高太阳浓度对垂直太阳电池n基中向pn结边界方向的有效电场分布的影响。在高太阳浓度下，电场的分布取决于pn结的高度。效率随着基座宽度的增加而提高，宽度可达25 $\mu$m。随着碱掺杂水平的降低，效率的提高与载流子迁移率的提高有关。还考虑了效率对太阳能集中的依赖性。效率在太阳集中约1000太阳时达到饱和。

The effect of geometrical sizes on efficiency of vertical silicon tunnel junction solar cell for high solar concentration

In the paper the effect of height, base width and doping level on efficiency of the silicon vertical solar cell with two p-n junctions connected by tunnel junction, is investigated by 2D simulations. It is shown that the dependence efficiency on the height of p-n junction has non monotonic behavior. It is attributed to impact of high solar concentration on distribution of effective electric field normal to p-n junction border in the n-base of vertical solar cell. The distribution of the field depend on the height of p-n junction at high solar concentration. Efficiency is increased with increasing the width of base up to 25 $\mu$m. Increasing of the efficiency with decreasing the base doping level is connected with increasing the carrier mobility. Dependence of the efficiency on solar concentration is also considered. Efficiency is reached the saturation at solar concentration around 1000 suns.
