Electrical doping (that is, intentional engineering of carrier density) underlies most energy-
related and optoelectronic semiconductor technologies. However, for the intensely studied …

Summary" Go big or go home" could never be a truer statement, especially when it comes to
energy. The world population is increasing, the energy use per person is growing more …

Flexible perovskite solar cells (f‐PSCs) have attracted great attention because of their
unique advantages in lightweight and portable electronics applications. However, their …

Defects in perovskite films are still the dominant destroyer of both power conversion
efficiency (PCE) and long‐term stability in perovskite solar cells (PSCs). As the most popular …

CsPbI3 nanocrystals with narrow size distributions were prepared to study the size-
dependent properties. The nanocrystals adopt the perovskite (over the nonperovskite …

Lead‐halide perovskite quantum dots (PQDs) or more broadly, nanocrystals possess
advantageous features for solution‐processed photovoltaic devices. The nanocrystal …

To fine‐tune surface ligands towards high‐performance devices, we developed an in situ
passivation process for all‐inorganic cesium lead iodide (CsPbI3) perovskite quantum dots …

Over the past few years, we have witnessed the occurrence and progress of the CsPbI3
semiconductor material as a superstar in photovoltaic fields. By the virtue of its excellent …

Lead halide perovskite quantum dots (PQDs), also called perovskite nanocrystals, are
considered as one of the most promising classes of photovoltaic materials for solar cells due …

Li-TFSI/t-BP are the most widely employed p-dopants for hole-transporting materials (HTMs)
within the state-of-the-art perovskite solar cells (PSCs). The hygroscopicity and migration of …
