This book presents a comprehensive overview of state-of-the-art quantum dot photodetectors, including device fabrication technologies, optical engineering/manipulation strategies, and emerging photodetectors with building blocks of novel quantum dots (e.g. perovskite) as well as their hybrid structured (e.g. 0D/2D) materials. Semiconductor quantum dots have attracted much attention due to their unique quantum confinement effect, which allows for the facile tuning of optical properties that are promising for next-generation optoelectronic applications. Among these remarkable properties are large absorption coefficient, high photosensitivity, and tunable optical spectrum from ultraviolet/visible to infrared region, all of which are very attractive and favorable for photodetection applications. The book covers both fundamental and frontier research in order to stimulate readers' interests in developing novel ideas for semiconductor photodetectors at the center of future developments in materials science, nanofabrication technology and device commercialization. The book provides a knowledge sharing platform and can be used as a reference for researchers working in the fields of photonics, materials science, and nanodevices.

The nanoscale phase stabilization of CsPbI3 quantum dots allows for the advantageous manipulation of its phase diagram. We show that these all inorganic halide perovskite nanocrystals can be used to fabricate colloidal perovskite quantum dot solar cells with incredibly low voltage losses. Despite recently emerging on the photovoltaic scene, CsPbI3 quantum dot solar cells have already achieved approximately 85% of their Shockley-Quessier limit open-circuit voltage, among the lowest voltage loss achieved for any material with a band gap of 1.7 eV, excepting III-V semiconductors. The low losses in these devices recently led to a world record certified quantum dot solar cell efficiency of 13.4%. While single junction thin film perovskite solar cells have surpassed 22% power conversion efficiency, perovskite-perovskite tandem solar cells offer the potential for power conversion efficiencies exceeding 30%. However, to accomplish this ambitious goal, perovskite solar cells must be designed with incredibly low losses and the appropriate band gaps, which differ from the ideal band gap for single junction perovskite solar cells. In this respect, the incredibly low voltage loss and tunable band gap of CsPbI3 quantum dots make them ideally suited for all-perovskite tandem solar cell applications.

Recently, lead halide perovskite quantum dots (QDs) have attracted much attention because of their excellent properties of high colour purity, tunable emission wavelength covering the whole visible region, and ultrahigh photoluminescence (PL) quantum yield. They are expected to be promising candidates for the next-generation cost-effective lighting and display sources. Here, we introduced the recent development in the direct solution-processed synthesis and ion exchange-based reactions, leading to organic/inorganic hybrid halide perovskites (CH3NH3PbX3; X = Cl, Br, I) and all-inorganic lead halide perovskites (CsPbX3; X = Cl, Br, I), and studied their optical properties related to exciton-related emission and quantum confinement effect. Finally, we reviewed the recent progresses on the perovskite light-emitting diodes (LEDs) based on CH3NH3PbX3 and CsPbX3 quantum dots and provided a critical outlook into the existing and future challenges.
