In article number 1701432 , Haiguang Zhao, Zhiming M. Wang, Federico Rosei, and co‐workers report near‐infrared (NIR), heavy metal‐free, colloidal “Giant” CuInSe 2 /CuInS 2 core/shell quantum dots (g‐QDs) with tunable absorption and photoluminescence (PL) spectra in the NIR region. These g‐QDs exhibit possess quasi type‐II band energy structure, which is favorable for energy applications. Using this type of QDs to fabricate the photoanode in a photoelectrochemical (PEC) cell demonstrates an efficient and stable PEC device for hydrogen generation. These results indicate that NIR, heavy metal‐free g‐QDs are promising, cost‐effective materials for environmentally friendly optoelectronic devices.
