摘      要：In this article,we focus on using the multiexciton generation(MEG)effect of quantum dot(QD)to realize quantum cutting of high-energy photons which will give rise to a remarkable increase of total photon *** avoid the complicated solving of Schro¨dinger equation,we take approximations and develop a method for fast evaluating the quantum efficiency of MEG *** this basis,we calculate the detailed balance limit of efficiency of Si single-junction solar cell with Si QD-doped glass placed on top of it as a spectral converter *** shows that the efficiency will reach 36%which is 6%higher than that without the converter *** have also explored the influence of QD radius,QD-doping density,QD,and host material,device working temperature on the efficiency.
