Best answer: What are the ideal material for fabrication of solar cell?

Crystalline silicon is selected for solar fabrication having a band gap of $1.7 – 1.8e{text{V}}$ also crystalline silicon has high quality of light absorption and as it is a semiconductor therefore it has electrical conductivity.

Which material is ideal for solar fabrication?

Crystalline silicon is the most common material used in solar cells. The lifespan of crystalline silicon cells is more than 25 years without deterioration, making it ideal for industrial solar power generation.

What are the materials used for making solar cells?

Solar cell

They convert sunlight into direct current (DC) electricity. A solar cell is made of two types of semiconductors, called p-type and n-type silicon. The p-type silicon is produced by adding atoms such as boron or gallium that have one less electron in their outer energy level than does silicon.

What are the ideal material for fabrication of solar cell and give the criteria for selection?

Material used in fabrication of solar cells. The material with band gap 1.5 e.V are ideal material for this purpose.

IT\'S FUNNING:  Frequent question: What do mitochondria use to produce energy for a cell?

Which material is ideal for solar cell fabrication and why?

Note: The material selected is crystalline silicon because of the favorable band gap and also the high absorption of the material for incident light.

Which material is suitable for solar cell construction and why?

Silicon – The Most Popular Material for Solar Cells

The molecular structure of single-crystal silicon is uniform. This uniformity is ideal for the transfer of electrons efficiently through the material. However, in order to make an effective photovoltaic cell, silicon needs to be “doped” with other elements.

What is solar cell name two materials mostly used for making solar?

The two materials used for making solar cells are silicon and Cadmium Telluride. EXPLANATION: The ‘solar cell’ also known as ‘photovoltaic cell’ has the capability of converting ‘light energy’ into electricity. This is done by a mechanism known as ‘photovoltaic effect’.

How are solar cells manufactured?

The production process from raw quartz to solar cells involves a range of steps, starting with the recovery and purification of silicon, followed by its slicing into utilizable disks – the silicon wafers – that are further processed into ready-to-assemble solar cells.

What are the materials used for preparing the 4 junction solar cells and why?

Multi-junction cells have materials tuned to specific wavelengths that absorb different solar wavelengths, thus maximizing how much sunlight it harvests. … The four material junctions are: gallium indium phosphide, a gallium arsenide, and two of gallium indium arsenide.

Which material is used in space solar panels and why?

Silicon solar cells have proved to be suitable for use in space applications, despite their own limitations. Silicon cells have generally lower efficiencies and significant radiation damage than others new materials.

IT\'S FUNNING:  What are renewable forms of energy?

Why are Si and GAAS preferred materials for solar cells?

Si and Ga have low threshold electron potential hence they are preferred in solar cell. Answer: A) these materials are preffered because of their lower value of energy gap. SO that they can be activated using solar radiation.
