我们已经从理论上分析了潜在的效率提高多结太阳能电池的效率，这是可以通过使用详细的平衡计算结合量子点。我们还实验研究了用金属有机物气相外延（MOVPE）在晶格匹配的GaAs上生长自组织InAs量子点和量子点阵列。通过原子力显微镜（AFM）的量子点的形态作为其生长参数的函数进行了研究。光致发光和光吸收测量表明，在GaAs结构中掺入InAs量子点（QD）可以提供亚GaAs带隙电子态
We have theoretically analyzed the potential efficiency improvement to multi-junction solar cell efficiencies which are available through the incorporation of quantum dot using detailed balance calculations. We have also experimentally investigated the Stranski-Krastanov growth of self-organized InAs quantum dots and quantum dot arrays on lattice-matched GaAs by metallorganic vapor phase epitaxy (MOVPE). The morphology of the quantum dots were investigated as a function of their growth parameters by atomic force microscopy (AFM). Photoluminescence and optical absorption measurements have demonstrated that the incorporation of InAs quantum dots (QD) into a GaAs structure can provide sub-GaAs bandgap electronic states
