Nanocrystals as performance-boosting materials for solar cells

“…[121][122][123] Meanwhile, TiO 2 NCs have been widely applied in n-i-p solar cells using chalcogenide NC as light harvesters, such as CdSe, CdS, and PbS.

“…Lead chalcogenide NCs, especially PbS, have been massively used as efficient top HTL in NC-LHSCs. 29–56 Additionally, other metal chalcogenide NCs are also excellent choices as top HTL for high-performance perovskite solar cells (PSCs), mainly containing CuInS 2 /ZnS (core/shell), 57 CdZnSe@ZnSe, 58 Cu 2 ZnSnS 4 /Se 4 , 59 SnS, 60 CuInSe 2 , 61 Ag–In–Ga–S, 62 Cu 12 Sb 4 S 13 , 63 Cu 2 SnS 3 , 64 CuGaS, 65 and CuInS 2 . 66 Metal oxide NCs of NiO have shown potential for hole transport on top of the light harvesting layer in PSCs and Si solar cells.…”

“…11,14,15,17–22 Additionally, perovskite NCs are also good alternatives for light harvesting in solar cells. 12–14,16,23–28 Besides active layers (light harvesting layers), functional layers based on NCs, mainly including hole transport layers (HTLs), 29–99 electron transport layers (ETLs) 100–173 and interfacial functional layers (IFLs), 174–221 are of great importance in solar cells. Notably, NC additives also boost the performance of solar cells through defect passivation, plasmonic effect, solar concentration, light up-conversion and down-conversion/shifting, light scattering and reflection, and heat sinks.…”

A Review on Materials and Technologies for Organic Large‐Area Electronics

“…Such alternatives encompass perovskite solar cells, organic solar cells, and quantum dot cells. [23,[430][431][432] Perovskite solar cells in particular are a very promising technology and are already produced by inkjet printing and commercialized by a company named Saule Technologies. [433] Smart packaging is another area that has been benefiting from these materials and technologies.…”
