DC Battery01:21

DC Battery

1.8K
A conductor needs to be a component of a path that creates a closed loop or full circuit to have a continuous current flowing through it. A current starts to flow if an electric field is created inside an isolated conductor that is not part of a full circuit. The conductor quickly develops a net positive charge at one end and a net negative charge at the other. These charges generate an electric field opposite the direction of the applied electric field, which reduces the current. Eventually,...

P-N junction01:11

P-N junction

1.7K
A p-n junction is formed when p-type and n-type semiconductor materials are joined together. At the interface of the p-n junction, holes from the p-side and electrons from the n-side begin to diffuse into the opposite sides due to the concentration gradient. This diffusion of carriers leads to a region around the junction where there are no free charge carriers, known as the depletion region. The charge density within the depletion region for the n-side and p-side can be described by the...

Transmission Line Design Considerations

817
Aluminum has become the material of choice for overhead transmission lines, surpassing copper due to its abundance and cost-effectiveness. The most prevalent type is the aluminum conductor, steel-reinforced (ACSR), which combines aluminum strands around a steel core. Other variants include all-aluminum conductors (AAC), all-aluminum alloy conductors (AAAC), aluminum conductor alloy-reinforced (ACAR), and aluminum-clad steel conductors. Advanced designs, such as aluminum conductors with steel...

Posttensioned Masonry Walls01:15

Posttensioned Masonry Walls

661

Post-tensioned masonry walls use high-strength steel rods or flexible tendons to enhance the strength and efficiency of masonry structures. These elements are securely anchored to the foundation and extend vertically either within the cores of the masonry units or between the masonry wythes. The construction process involves building the wall with these tensioning elements in place and allowing the mortar to fully cure.
Following the curing process, the tensioning begins. Steel rods are...

Area of Science:

  • Materials Science
  • Renewable Energy
  • Photovoltaics

Background:

  • Wide-bandgap (WBG) perovskite solar cells (PSCs) are crucial for high-efficiency tandem devices.
  • Bromine-iodine (Br-I) mixed-halide PSCs face challenges with Br-I phase segregation under operational conditions, limiting voltage and stability.
  • Defect formation during rapid crystallization of Br-rich perovskites further hinders performance.

Purpose of the Study:

  • To develop highly stable and efficient WBG PSCs using Br-I mixed-halide perovskite.
  • To mitigate Br-I phase segregation and reduce defect density in perovskite films.
  • To create efficient all-perovskite tandem solar cells.

Main Methods:

  • Combined rapid Br crystallization with a gentle gas-quench method.
  • Prepared highly textured columnar 1.75-electron volt Br-I mixed WBG perovskite films.
  • Integrated WBG PSCs with narrow-bandgap PSCs into a two-terminal tandem device.

Main Results:

  • Achieved 1.75-electron volt WBG PSCs with over 20% power conversion efficiency and 1.33-volt open-circuit voltage (Voc).
  • Demonstrated excellent operational stability with less than 5% degradation over 1100 hours at 65°C under 1.2 sun.
  • Fabricated a 27.1% efficient all-perovskite tandem solar cell with a 2.2-volt Voc.

Conclusions:

  • The gas-quench method effectively produces stable, efficient WBG perovskite films by reducing defect density and phase segregation.
  • The developed WBG PSCs are suitable for high-performance tandem solar cell applications.
  • The all-perovskite tandem device shows significant potential for future solar energy conversion.
