Perovskite can be used to fabricate solar cells and LEDs.

In this project we manufacture dual functionality devices that can function as both solar cells and LEDs. We investigate the influence of different fabrication steps. on the device performance as an LED vs solar cell.

  My project focuses on developing a CsPbBr₃-based LED in the visible range using a fully printable, triple-mesoporous oxide structure. This architecture, originally designed for stable perovskite solar cells, features a mesoporous indium tin oxide (ITO) layer as the counter electrode instead of noble metals or carbon. The design is free of a hole transport layer (HTL), with the perovskite itself serving both as the light-emitting material and the hole transport medium. By adapting this structure for electroluminescence, the goal is to achieve efficient and stable LED performance.

The mesoscopic ITO PSCs have a unique structure,  composed of three mesoporous layers containing the perovskite. The structure, developed in our lab, presents over 10% efficiency, and is also capable of performing as a highly efficient LED achieving over 22% EQE. Mesoporous Indium tin oxide (ITO) functions here as the back contact. The mesoscopic stack creates a scaffold for the perovskite solution to percolate and crystalize inside it. Screen printing is a simple and affordable fabrication method, common in the industry and suitable for large-scale production. In our recent projects, we are focusing on achieving high-efficiency ITO-PSCs, and developing this structure as an all inorganic printable LED as well.

The ITO perovskite solar cell structure consists of triple-oxide screen-printed mesoporous layers. This unique structure has several advantageous, such as enhanced stability and renewability comparing to the other screen-printed structure with carbon counter electrode. In addition to the simple and scalable fabrication method, this solar cell structure is a good candidate for large-scale production. This structure can reach 15.3% efficiency, and we are working on enhancing it by inserting gold nano particles to the lab-made ITO printing paste, and adding a hole transport layer layer to the structure.

Due to their remarkable optical and physical properties perovskite nanoparticles (PeNPs) are intensively investigate in the past years. PeNPs characterized with high photoluminescence quantum yield (PLQY), narrow full width half maximum of emission and tunable band gap. These properties enable to use PeNPs in light emitting diodes (LEDs), lasers, sensors, and photodetectors.

In our lab we are synthesizing, characterizing and studying perovskite nano-structures. We are taking the research one step ahead by fabrication of unique nano- structures based on perovskite nano particles and study interactions within the structures, self-assembly processes, and changes in optical properties of those structures.

Materials with self-healing capabilities have been in development for years and are used for a variety of useful applications that require stability and healing capabilities over time. Most of the existing materials are macroscopic materials based on complex and in some cases expensive external additions. In this project we are developing nanoparticles with a full inorganic composition in the form of Cs₂ZnX₄ (X= Cl, Br) that can perform healing at the microscopic level. These nanoparticles are semiconductors and can be used in a variety of different optoelectronic applications that require stability and durability over time at the atomic level. Moreover, these compositions are low-toxic and environmentally friendly, which makes it a promise in the field of semiconductors.

The layers of Perovskite solar cells are usually prepared by the spin-coating method. The thermal evaporation method suggests the formation of a uniform layer, avoiding the use of solvents and solubility issues, and enables the synthesis of perovskite solar cells in a broad scale. In this project we are aiming to develop a fully evaporated perovskite using different elements.

An interesting and important property of the perovskite is the possibility to make it transparent, thus enabling fabrication of semi-transparent solar cells. 

This project concentrate  on semi-transparent perovskite solar cells, based on a method, in which self-assembled perovskite precursor solution forms a transparent grid structure.

Project responsible: Vikas Sharma

Transparent solar cells can be used for different applications, such as glasses or windows. Usually, the transparent solar cells are less efficient due to their wide band gap. In this project we studied several perovskites and other materials to get transparent solar cells

Zero-dimensional inorganic perovskites has the general chemical formula of Cs₄PbX₆ (X = Cl^–, Br^–, or I^–), those materials have high percent of PLQY (photoluminescence quantum yield) due to strong quantum-confined environment that stems from the isolation of [PbBr₆]^4– octahedra clusters from one another by the surrounding monovalent metal ions. We are working on using this unique property in LED (light-emitting diode) devices to achieve emitting device.
