Design Principles of Silicon Heterojunction Solar Cells with Dopant‐Free Interdigitated Back Contacts

Figure 2. a) Accumulated number of related articles as a function of time for the search strings given in the legend taken from ISI Web of Science. Proportion of all-inorganic perovskite solar cells are also shown. b) Relationship between champion efficiencies and the accumulated number of related articles. c) The champion power conversion efficiencies of all-inorganic perovskite solar cells along with years. The devices are classified into 5 groups by the iodine to bromine ratio quantified via the value of x. The efficiencies of hybrid perovskite solar cells are also shown for comparison. The devices with Sn doping process are not shown in the figures, because the bandgap deviates significantly from the intrinsic values. d) The champion efficiency of different all-inorganic perovskite solar cells compared with the SQ limit. The record efficiency of c-Si, GaAs and hybrid perovskite solar cells are shown for comparison.

Hybrid metal‐halide perovskites (MHPs) have shown remarkable optoelectronic properties as well as facile and cost‐effective processability. With the success of MHP solar cells and light‐emitting diodes, MHPs have also exhibited great potential as gain media for on‐chip lasers. However, to date, stable operation of optically pumped MHP lasers and electrically driven MHP lasers—an essential requirement for MHP laser's insertion into chip‐scale photonic integrated circuits—is not yet demonstrated. The main obstacles include the instability of MHPs in the atmosphere, rudimentary MHP laser cavity patterning methods, and insufficient understanding of emission mechanisms in MHP materials and cavities. This review aims to provide a detailed overview of different strategies to improve the intrinsic properties of MHPs in the atmosphere and to establish an optimal MHP cavity patterning method. In addition, this review discusses different emission mechanisms in MHP materials and cavities and how to distinguish them.

Metal halide perovskites having high defect tolerance, high absorption characteristics, and high carrier mobility demonstrate great promise as potential light harvesters in photovoltaics and optoelectronics and have experienced an unprecedented development since their occurrence in 2009. Semiconductor quantum dots (QDs), on the other hand, have also been proved to be very flexible toward shape, dimension, bandgap, and optical properties for constructing optoelectronic devices. Of late, a strategic combination of both materials has demonstrated extraordinary promise in photovoltaic applications and optoelectronic devices. Combining QDs and perovskites has proved to be quite an effective strategy toward the formation of pinhole‐free and more stable perovskite crystals along with tunability of other properties. To boost this exciting research field, it is imperative to summarize the work done so far in recent years to provide an intriguing insight. This review is a critical account of the advanced strategy toward combining these two fascinating materials, including their different synthetic approaches regarding heteroepitaxial growth of perovskite crystals on QDs, carrier dynamics at the interface and potential application in the field of solar cells, light emitting diodes, and photodetectors.
