Recent development and understanding of polymer–nanocrystal hybrid solar cells

Abstract: This review presents a general overview of polymer–nanocrystal hybrid solar cells (HSCs). The device structure and operation mechanism of bulk heterojunction HSCs are introduced, and recent works that have been done to improve the device performance or clarify the operation mechanism are summarized and discussed in detail. Also, the challenges and perspectives of HSCs are presented.

“…Solution-processed nanocrystal (NC) solar cells have demonstrated as a candidate for low cost, environmentally friendly, and large scale “roll to roll” printing product due to their low raw material consumption and simple fabrication process [ 1 , 2 , 3 ]. Recently, intensive investigations have been focused on CdTe NC solar cells with an inverted structure [ 4 , 5 ]. Comparing to the conventional CdTe NC solar cells using indium tin oxide (ITO) as the anode, devices with an inverted structure have many advantages, such as long-term stability under ambient conditions by avoiding the usage of low work-function metal cathode on the top of the device and better photon absorption efficiency due to the small distance between the active layer and the illumination source [ 6 , 7 ].…”

“…The intimate contact between the active layer and hole/electron blocking layers is essential for blocking injected charges and effectively collecting carriers to the electrodes (Chen et al, 2017 ; Cheng et al, 2019 ). However, these additional layered transporting and blocking layers deposited by spin-coating or thermal evaporation have a low mobility lifetime and high trap density because these layers are amorphous and have lattice mismatch on PSC interfaces (Lin et al, 2015 ; Zhang et al, 2017 ).…”
