Researchers use ligand-passivation engineering to achieve high performance indoor perovskite quantum dot photovoltaics

Researchers at Korea University, Kyungpook National University, Hanyang University, Dongguk University and Mississippi State University have used a novel ligand passivation strategy in perovskite quantum dots (PQDs) photovoltaics (PQDPVs) to enhance the carrier lifetime. 

The advancement of perovskite photovoltaic (PePV) systems for harnessing indoor light energy has been accelerated by the advent of the Internet of Things (IoT). However, the commercialization of these systems is impeded by moisture instability and restricted carrier lifetimes. Perovskite quantum dots (PQDs) offer viable solutions for increasing stability despite the potential effects of their organic ligands on efficiency.

Researchers design multifunctional display based on photo-responsive perovskite light-emitting diodes

Researchers at Linköping University, Nanjing University and NanjingTech have developed a multifunctional display that uses photo-responsive metal halide perovskite LEDs as pixels. The perovskite LED display can be simultaneously used as a touch screen, ambient light sensor and image sensor (including for fingerprint drawing) without integrating any additional sensors. The light-to-electricity conversion efficiency of the pixels also allow the display to act as a photovoltaic device that can charge the equipment.

This is a step forward compared to current display screens, which are typically only used for information display, but can have a range of different sensors integrated into them for functions such as touch control, ambient light sensing and fingerprint sensing. According to the team, photo-responsive light-emitting diodes (LEDs), which can display information and respond to light excitation, could be used to develop future ultra-thin and large screen-to-body ratio screens. However, photo-response is difficult to achieve with conventional display technologies.

Researchers provide a roadmap for the optical properties of perovskite/perovskite/silicon triple-junction cells

Researchers from the University of Freiburg and Fraunhofer ISE recently put together a roadmap for the optical properties of perovskite/perovskite/silicon triple-junction cells. They investigated the optical properties of perovskite/perovskite/silicon triple-junction cells and found these devices may have a practical efficiency potential of 44.3% assuming idealized electrical parameters. These cells may also potentially achieve a fill factor of 90.1%.

The group of researchers developed a comprehensive optoelectrical simulation model for triple-junction solar cells based on subcells relying on perovskite, perovskite, and crystalline silicon, respectively. The model aims to define an efficiency roadmap for improving the optical properties of these solar cells within realistic boundary conditions.

Unlocking the Potential of Perovskite Manufacturing with Vacuum Evaporation Tools

This is a sponsored post by MBRAUN

In the quest for cleaner, more efficient energy sources, perovskite solar cells have proven to be a promising prospect. Their exceptional efficiency, low-cost production and versatility make them a promising candidate for revolutionizing the renewable energy. However, the road to mass adoption faces hurdles, one of which is the need for precise and efficient manufacturing processes. Here's where vacuum evaporation tools shine as indispensable assets in the production of perovskite solar cells.

Precision Engineering for Optimal Performance

At the heart of perovskite solar cell fabrication lies the deposition of thin films with utmost precision under highly controlled conditions. MBRAUN evaporation tools from the PEROvap series offer unparalleled control over the deposition process, ensuring the uniformity and consistency essential to maximize solar cell efficiency. Addressing the volatility of most used Perovskite materials PEROvap systems are designed to control the temperature of the chamber, the substrate holder, the sources and the quartz crystals precisely from -40°C up to room. This avoids unwanted re-evaporation of already deposited materials and stabilizes the overall evaporation process. By vaporizing the material under vacuum conditions and depositing it onto the substrate, PEROvaps also eliminate impurities and defects that could affect performance, resulting in high-quality perovskite films with superior optoelectronic properties.

In backlighting systems for LCDs, conventional red, green, and blue (RGB) light sources that lack polarization properties can result in a significant optical loss of up to 50% when passing through a polarizer. To address this inefficiency and optimize energy utilization, the scientists developed a high-performance device designed for RGB polarized emissions. The device uses an array of semipolar blue µLEDs with inherent polarization capabilities, coupled with mechanically stretched films of green-emitting CsPbBr3 nanorods and red-emitting CsPbI3-Cs4PbI6 hybrid nanocrystals.
