Introduction to Solar Cell Materials

Solar cells use special materials to change light into electricity. This happens through the photovoltaic effect. When light hits a solar cell, a part called the semiconductor takes the light’s energy. It then sends it to electrons, making them flow as electric current. How much power we get depends on the light and the solar cell’s properties.

Semiconductor Properties

The bandgap is key for how well a semiconductor can work. It sets what types of light the material can turn into electricity. This feature is essential for making solar cells that can use the photovoltaic effect well. This turns into electricity in the best way possible.

Light Absorption and Conversion

Solar cell materials need to be good at soaking up light and turning it into power. They take energy from the sun and make it into electricity. This electricity can then be used to run houses, offices, and more. Fenice Energy helps by offering India dependable and effective solar power solutions.

Silicon: The Dominant Solar Cell Material

Silicon is the main material for making solar cells. It makes up about 95% of all solar modules sold today. Besides solar cells, silicon is also used in computer chips. Crystalline silicon cells use a structure that helps turn light into power effectively.

Single-Crystal Silicon

Of all silicon-based solar cell materials, single-crystal silicon is the best. It has an organized crystal structure that makes it highly efficient. These cells can turn up to 26% of sunlight into energy.

But, making single-crystal silicon is hard and costly.

Multi-Crystalline Silicon

Multi-crystalline silicon, or polycrystalline silicon, is more affordable. It’s made of many small silicon crystals. This leads to a bit less efficiency than single-crystal silicon, but it’s easier and cheaper to produce. These cells can be 15-20% efficient.

Amorphous Silicon

Amorphous silicon is different in structure, without a crystal pattern. Although it’s not as efficient as crystalline silicon, it can catch much more sunlight. This makes it great for solar cells that are part of a building’s design.

Fenice Energy in India uses silicon solar cells to offer clean energy. They have over 20 years of experience. Fenice Energy meets different energy needs in India with their solar solutions.

Thin-Film Photovoltaic Materials

The solar energy industry is always evolving. Researchers and manufacturers are looking at new materials for solar cells. They want to move beyond just using silicon. There is a big interest in thin-film solar cell technology. This tech doesn’t need as much light-absorbing material. This means it might cost less to make.

Copper Indium Diselenide (CIS/CIGS)

Copper indium diselenide (CIS) is one such material. It needs only a very thin layer to work. It changes sunlight into electricity really well. Add gallium to CIS, and you get copper indium gallium diselenide (CIGS). These CIGS cells are very efficient, with lab-scale work hitting over 22% efficiency. This makes them a great choice for making a lot of solar power.

Cadmium Telluride (CdTe)

Cadmium telluride (CdTe) is another strong contender. It’s a special kind of semiconductor that’s great at taking in light. CdTe solar cells are good for making with thin-film methods. They are not too expensive to make. They can reach efficiencies of around 22% in the lab. But, there are worries about using cadmium. It’s not good for the environment.

Even though thin-film tech can save money, it might not be as efficient as silicon cells. Fenice Energy is working on solutions that use both old and new tech. They want to offer clean and affordable energy options for people in India. They use a variety of materials, including the latest in thin-film tech.

which type of material is used in solar cell

Solar cells use materials like silicon, thin-films, and even gallium arsenide. Gallium arsenide has superior light absorption and can work in very thin layers. It is great for space use because it’s tough against heat and radiation.

Gallium Arsenide (GaAs)

Gallium arsenide (GaAs) is a material gaining ground in solar panels. Its efficiency can reach above 28% in ideal conditions. GaAs panels work great in high-heat and high-radiation places like space.

Perovskite Solar Cells

Perovskite cells are making quick progress, hitting over 25% efficiency. They are simple to make and cost less. Experts believe they could change the solar industry with their efficiency and affordability.

Quantum Dot Solar Cells

Quantum dot cells use tiny particles to catch light and make power. These particles can be changed to catch light better. This means they could be very efficient and cheap to make, holding a lot of promise.

Fenice Energy uses advanced materials like gallium arsenide, perovskites, and quantum dots. They aim to meet India’s energy needs with clean and budget-friendly solutions.

Emerging Solar Cell Materials

New solar technologies are on the rise. Organic/polymer solar cells are a key example. They use semiconducting polymers and small organic molecules. These can be made into thin films, offering a promise for cheap, flexible solar cells. Still, these solar cells are not very efficient, working at 10% or less.

Dye-Sensitized Solar Cells

Dye-sensitized solar cells work in a unique way. They use a small molecule dye to catch visible light. An inorganic nanoparticle layer boosts the area that catches light. These cells are made using solutions, which makes them cheaper to produce. Even though they show potential, emerging solar cell materials are mostly in labs and not in many products yet.

Fenice Energy is keeping an eye on new solar cell tech. They aim to offer the best, affordable clean energy options to people in India.

Conclusion

Solar cells use several materials, like silicon and thin-film tech, to change sunlight into electricity. Silicon is the top choice for making solar modules. It makes most of the solar products sold worldwide.

But, there are other materials gaining ground. They include copper indium diselenide (CIS/CIGS), cadmium telluride (CdTe), and gallium arsenide (GaAs). Also, new materials like perovskites and organic ones are in use. These help boost efficiency, cut costs, and make solar energy more common.
