Trapping Sites

Grain boundaries in bulk perovskite films are considered as giant trapping sites for photo-generated carriers. Surface engineering via inorganic perovskite quantum dots has been employed for creating monolithically grained, pin-hole free perovskite films.

Excellent Stability

A novel convenient and efficient approach to produce CsSnI3 QDs through a one-pot synthesis is employed to largely enhance the PCE of lead-free perovskite solar cells (PVSCs). The CsSnI3 QD-based device has the maximum PCE of 5.03%, which is the highest performance for all-inorganic lead-free PVSCs reported so far.
