One approach for improving the power conversion efficiencies (PCEs) of inverted perovskite solar cells (PSCs) has been to use self-assembled monolayers (SAMs), such as [2-(9H-carbazol-9-yl)ethyl]phosphonic acid (2PACz) and its derivatives, as hole transport materials (HTMs) (1, 2).The main reasons why SAMs enhance PCEs compared with
Carbon dots (CD) derived from chemical sources require an additional input of passivation agent, which is not a requirement for the ones synthesized from natural sources. The CD show bright luminescence, predominantly in the blue region which are applicable in a wide range of applications. In the current work we have used the flowers of Bougainvillea
Self-assembly is a process by which individual units, such as colloidal nanoparticles and protein molecules, are arranged spontaneously into a highly ordered structure [1] 1959, Richard Feynman coined the concept of self-assembly in his famous talk titled, "There''s Plenty of Room at the Bottom" [2].He envisioned a world in which atoms can be

Abstract. The charge-selective contacts play a crucial role in the charge dynamics of solar cells. In the fast race to achieve higher power conversion efficiencies in perovskite-based devices, the avoidance of the detrimental effects due to interfacial charge recombination and/or poor charge extraction is the key to achieving high performance devices.
Three major self-assembly methods are currently employed for the synthesis of III-V nanowire heterostructures: (i) metal-catalyst assisted growth, (ii) self-catalyzed growth and (iii) selective-area epitaxy (SAE).
