Energy harvesting, which converts wasted environmental energy into electricity by utilizing various physical effects, hasattracted tremendous research interests as is one of the key technologies to realize advanced electronics in the future. In this review, we introduce recent progress in the field of hybrid energy harvesting technology. In particular, we focus on a quantum dots (QD)‐based hybrid energy harvesting device. Attributed to fascinating material properties that QD possess, employment of QDs into hybrid energy harvesting has shown great potential for independent and sustainable energy supply.First, an integration of a QD solar cell into a mechanical energy harvester is discussed to harness different types of environmental energy sources simultaneously. Second, a comprehensive explanation of a piezotronic and piezo‐phototronic effect is provided, which is followed by QD‐based piezo‐phototronic applications. Finally, we summarize recent progress that has been made in energy harvesting technology involving a photovoltaic and piezo/triboelectric effect

1D semiconductor materials are widely used in the fields of energy conversion, electronics, and photoelectrical devices, due to their unique ability to connect the nanometer and macroscopic worlds. Among them, 1D‐ZnO plays a vital role in the construction of photoelectrical devices due to its easily modulated morphology and band structure. By combining 1D‐ZnO with other materials to form a variety of heterostructures, the functional diversity of 1D‐ZnO is greatly enriched. Through the means of interface engineering, the behavior of carriers in 1D‐ZnO‐based heterostructures can be adjusted to optimize its photoelectrical performance. A comprehensive understanding of the different integration methods and interface engineering of 1D‐ZnO‐based heterostructures can provide new and more effective methods for the design of next‐generation photoelectrical devices. In this paper, starting with the precise growth of 1D‐ZnO, 1D‐ZnO‐based heterostructures constructed by traditional epitaxial growth and emerging van der Waals stacking are emphatically summarized. The modulation mechanisms by interface engineering on the photoelectrical performance of the above two types of heterostructures are systematically reviewed. Finally, the opportunities and challenges of interface engineering in 1D‐ZnO‐based heterostructures for next‐generation photoelectrical devices are prospected.

Solar‐driven interfacial evaporation (SDIE) has played a pivotal role in optimizing water‐energy utilization, reducing conventional power costs, and mitigating environmental impacts. The increasing emphasis on the synergistic co‐generation of water and green electricity through SDIE is particularly noteworthy. However, there is a gap of existing reviews that have specifically focused on the mechanistic understanding of green power from WEC systems, the structure‐activity relationship between efficiency of green energy utilization in WEC and materials design in SDIE. Particularly it lacks a comprehensive discussion to address the challenges faced in these areas along with potential solutions. Therefore, this review aims to comprehensively assess the progress and future perspective of green electricity from water‐electricity co‐generation (WEC) systems by investigating the potential expansion of SDIE. Firstly, it provides a comprehensive overview about materials rational design, thermal management and water transportation tunnels in SDIE. Then it summarizes diverse energy sources utilized in the SDIE process, including steaming generation, photovoltaics, salinity gradients effect, temperature gradients effect, and piezoelectric effect. Subsequently, it explores factors that affect generated green electricity efficiency in WEC. Lastly, this review proposes challenges and possible solution in the development of WEC. The timely emergence of this review will promote the sustainable use of energy.This article is protected by copyright. All rights reserved
