“…Nanocrystals such as semiconductor quantum dots (QDs) have the unique property in that the bandgap can be modulated by changing the size of the QDs. With such versatility in their design and the compatibility with solution processing (colloidal QDs), these materials provide an inexpensive route for spectral matching via LDS [11], [20]- [22] and non-radiative energy transfer [20], [23]- [25]. Among the QD species considered for PV applications, perovskite nanocrystals are among the most interesting and have gained substantial attention in recent years [26]- [28].…”
