全背肖特基接触薄膜光化学

All-Back-Schottky-Contact Thin-Film Photovoltaics

Marco Nardone

摘要:

介绍了全背肖特基接触(ABSC)薄膜光伏器件的概念,并利用二维数值模拟进行了评估。内建场是由具有不同功函数的两种金属的贯通肖特基结沿器件背面交替并排形成的。该方法使电荷传输所需的界面的数量最小化,同时消除了对透明导电前接触、PN结和划线的需要。性能指标的计算范围内的设计参数,它表明,前表面和背接触的钝化是至关重要的,以实现效率接近20%,仅使用一层材料沉积在背接触。这种设计范例可以提供宽范围的钝化材料,因为任何一个钝化层都不需要导电性和光学透明性。

英文摘要:

The concept of All-Back-Schottky-Contact (ABSC) thin-film photovoltaic devices is introduced and evaluated using 2D numerical simulation. The built-in field is generated by reach-through Schottky junctions with two metals of different work functions in an alternating, side-by-side pattern along the back of the device. This approach minimizes the number of interfaces through which charge transport is required while eliminating the need for transparent conductive front contacts, pn junctions, and scribing. Performance metrics are calculated for a range of design parameters and it is shown that passivation of the front surface and back contacts is critical to achieve efficiencies near 20% using only one layer of material deposited on the back contacts. This design paradigm may afford a wide range of passivation materials since both electrical conduction and optical transparency would not be required of any one passivation layer.
