摘要

摘要研究了∧梯度氮化铟镓(InGaN)太阳能电池的光学特性。设计了铟组成增加到xmax,然后以∧形图案减少的渐变InGaN阱结构。通过极化掺杂,这自然会产生交替的p型和n型区域。通过将铟合金轮廓从GaN改变到20%至90%的最大铟浓度,同时保持100nm的恒定总结构厚度,来设计单独的结构。考虑了在完全应变和松弛条件下的太阳能电池参数。结果表明,最大效率为  %   xmax出现完全应变状态  =  60  %  . 在宽松条件下,xmax的太阳能电池效率最高可达8.3%  =  90  %  . 维加定律预测了松弛条件下的带隙,而类维加定律是根据nextano的输出经验确定的™ 以计算应变下的太阳能电池参数。

Modeling of Λ-graded InxGa1−xN solar cells: comparison of strained and relaxed features
Abstract. The optical properties of Λ-graded indium gallium nitride (InGaN) solar cells are studied. Graded InGaN well structures with the indium composition increasing to xmax and then decreasing in a Λ-shaped pattern have been designed. Through polarization doping, this naturally creates alternating p- and n-type regions. Separate structures are designed by varying the indium alloy profile from GaN to maximum indium concentrations ranging from 20% to 90%, while maintaining a constant overall structure thickness of 100 nm. The solar cell parameters under fully strained and relaxed conditions are considered. The results show that a maximum efficiency of ≅5.5  %   under fully strained condition occurs for xmax  =  60  %  . Solar cell efficiency under relaxed conditions increases to a maximum of 8.3% for xmax  =  90  %  . Vegard’s law predicts the bandgap under relaxed conditions, whereas a Vegard-like law is empirically determined from the output of nextnano™ for varying indium compositions to calculate the solar cell parameters under strain.
