Energy level tuned indium arsenide colloidal quantum dot films for efficient photovoltaics

Existing n-type colloidal quantum dot materials easily lose their doping polarity in air. Here Song et al. passivate the reactive covalent surface of indium arsenide quantum dots to gain the energy-level tunability and show p–n junction type solar cells with 7.92% certified efficiency.
