Open-circuit voltage loss in perovskite quantum dot solar cells

Abstract

Perovskite quantum dots with superior phase stability and multiple exciton generation effects make them emerging as a competitive candidate in next-generation solar cells. However, given that the voltage loss in...

In Situ Iodide Passivation Toward Efficient CsPbI3 Perovskite Quantum Dot Solar Cells

“…2a and S1, S6). Good size uniformity is crucial for charge carrier non-radiative recombination as a wide size distribution causes the broadening of the band-tail states which aggravates the energetic disorder [41,42]. To analyze this, TEM images were obtained and the QD size distribution was examined.…”

Dimensional diversity (0D, 1D, 2D, and 3D) in perovskite solar cells: exploring the potential of mixed-dimensional integrations

“…There is a substantial body of literature, and we have come across a number of interesting review articles, each of which concentrated on a particular feature or characteristic of perovskite materials including 1D materials for efficient and stable PSCs, 75 solar cells with perovskite quantum dots, 5,76–79 nanocrystals in luminescent solar concentrators, 80 metal halide perovskite nano/microwires, 81 and metal halide perovskite nanorods. 82 There are still gaps in our understanding of the potential of perovskite solar cells because none of these articles provided a comprehensive analysis of the entire dimensional spectrum.…”

Green-route manufacturing towards future industrialization of metal halide perovskite nanocrystals

“…11–13 With the unique property of the multiple exciton generation (MEG) effect, 14 PeNCs have been extensively investigated in solar cells. 15–17 Up to now, the external quantum efficiency (EQE) of PeNC LEDs for red, green, and blue emissions have reached ∼29%, 18 ∼22%, 19 and ∼12%, 20 respectively, and the EQE of PeNC-based solar cells has been up to 17.4%. 21 These achievements have stimulated fascinating research of PeNCs over the past decade.…”
