Carrier lifetime is a critical parameter in semiconductor physics, representing the average time a charge carrier, such as an electron or hole, exists before recombination. It influences the efficiency of devices like solar cells and transistors by affecting charge transport and recombination rates.

A hole is a void or empty space within a solid object, surface, or area, often characterized by its boundary or perimeter. It can be naturally occurring or man-made, and serves various functions or purposes depending on its context, such as facilitating passage, providing access, or acting as a structural feature.

efficiency of devices

Solar cells, also known as photovoltaic cells, convert sunlight directly into electricity through the photovoltaic effect. They are a key technology in renewable energy, offering a sustainable solution to reducing dependence on fossil fuels and minimizing environmental impact.

solar cells

Transistors are semiconductor devices used to amplify or switch electronic signals and electrical power, forming the fundamental building blocks of modern electronic devices. They revolutionized technology by enabling the miniaturization and increased power of circuits, leading to the development of computers, smartphones, and other digital devices.

Recombination rates refer to the frequency at which genetic recombination occurs between different loci during meiosis, significantly impacting genetic diversity and evolution. These rates can vary widely across species and even within genomes, influenced by factors such as chromosomal architecture, environmental conditions, and evolutionary pressures.
