Question

Which region of a p-n junction is critical to the capture of solar energy by preventing recombination?

Answer 1

Answer:

eat and light from the Sun, solar energy, is one of the cleanest and most abundant ... Single-junction silicon solar cells convert light from about 300 nm to 1100 nm. ... The key to efficient conversion of sunlight into electricity is to develop ... The losses due to carrier recombination in any of the three regions

Answer 2

Semi-conductor

Semi-conductor region of a p-n junction is critical to the capture of solar energy by preventing recombination.

• In order to generate a voltage and useful work, a pn junction separates the electron and hole carriers in a solar cell. Other methods of extracting carriers from a solar cell include carrier-selective contacts2,3, and metal-insulator-semiconductor-based extraction1.
• This phenomenon is used by a solar cell to transform light energy into electrical energy. Photovoltaic cells are referred to as solar cells when sunlight is used as an incident photon. A solar cell is essentially a large-surface area p-n junction that can transform solar radiation into electrical energy.
• PN junctions in semi-conductors are widespread. They are an integral component of electronic and opto-electronic devices like solar cells, which convert solar energy into electrical energy, LEDs, rectifier diodes, and transistors.
• The "photovoltaic effect" is a process that creates voltage in a solar cell. Moving electrons to the n-type side of the junction and holes to the p-type side is a result of the p-n junction's collection of light-generated carriers.
