Improved efficiency of InAs/GaAs quantum dots solar cells by Si-doping
通過(guò)硅摻雜提高InAs和GaAs量子點(diǎn)電池的光電轉(zhuǎn)換效率
a b s t r a c t
This paper reports on significantly improved efficiency of InAs/GaAs quantum dot (QD) solar cells bydirectly doping Si into InAs QDs during the QD growth. The devices which contain five stacked QDs intheir i-regions were grown using molecular beam epitaxy. It is shown that using appropriate Si-doing,the open-circuit voltage of the device can be increased to 0.84 V. This is dramatically higher than theva lue of 0.67 V obtained in undoped device using the same structure. Moreover, the efficiency ofcorresponding device is improved from 11.3% to 17.0%. This improvement in efficiency is attributed togreatly reduced energy loss in the devices that results from the reduction of the defect density in thestacked InAs/GaAs QD layers due to the doping.
