An n-n type heterojunction enabling highly efficient carrier separation in inorganic solar cells
文献摘要：
Carrier separation in a solar cell usually relies on the p-n junction.Here we show that an n-n type inorganic semicon-ductor heterojunction is also able to separate the exciton for efficient solar cell applications.The n-n type heterojunction was formed by hydrothermal deposition of Sb2(S,Se)3 and thermal evaporation of Sb2Se3.We found that the n-n junction is able to enhance the carrier separation by the formation of an electric field,reduce the interfacial recombination and gen-erate optimized band alignment.The device based on this n-n junction shows 2.89％net efficiency improvement to 7.75％when compared with the device consisted of semiconductor absorber-metal contact.The study in the n-n type solar cell is expected to bring about more versatile materials utility,new interfacial engineering strategy and fundamental findings in the photovoltaic energy conversion process.
