Panel Types: Semi-Cut Solar Cell Technology

With the rapid increase in the number of rooftop solar installations, developers have been searching for new ways to optimize their installation. One way to do this is by cutting off only a portion of a panel’s surface area, which can reduce installation costs and make electrical production more efficient. Find out more in this post!

What is a semi-cut solar cell?

A semi-cut solar cell is a type of solar cell that has been cut in half vertically. The top half of the cell is still connected to the bottom half, but the two halves are not connected electrically. This allows for more light to reach the active area of the cell, which increases the amount of power that can be generated into solar energy. Semi-cut solar cells are more efficient than traditional solar cells, but they are also more expensive.

Pros and Cons of Semi-Cut Solar Cells

Semi-cut solar cells are a type of solar cell technology that is becoming increasingly popular. They have a number of advantages over traditional solar cell technologies, but there are also some disadvantages that should be considered before making the switch.

The biggest advantage of semi-cut solar cells is that they are much more efficient than traditional solar cells. This means that they can generate more electricity from the same amount of sunlight, making them ideal for use in areas with high levels of sunlight. They are also less likely to suffer from shading issues, as the semi-cut design means that there are no exposed surfaces for shadows to fall on.

Another advantage of semi-cut solar cells is that they tend to be more durable than traditional solar cells. This is because the way they are manufactured means that they are less likely to be damaged by wind, hail or other debris. This makes them ideal for use in areas where severe weather conditions are common.

However, there are also some disadvantages to using semi-cut solar cells. One of the biggest is that they can be more expensive than traditional solar cells. This is because the manufacturing process is more complex and requires specialised equipment. Additionally, semi-cut solar cells tend to have a shorter lifespan than traditional solar cells, so they will need to be replaced more frequently.

How does Semi-Cut Solar Cell Technology work?

Semi-cut solar cell technology involves the use of a silicon wafer that has been cut into two halves. One half of the wafer is then used to create a solar cell, while the other half is used as a back contact. The back contact is made from a material that is transparent to infrared light, such as indium tin oxide (ITO). This allows sunlight to pass through the back contact and reach the active region of the solar cell, where it can be converted into electricity.

The advantage of using semi-cut solar cell technology is that it allows for higher levels of efficiency than traditional solar cells. This is because there is no need for an electrical connection between the front and back of the solar cell, which can reduce efficiency. Additionally, semi-cut solar cells can be made with thinner wafers than traditional solar cells, which also reduces loss due to absorption.

Types of panels according to efficiency

Solar panels are classified according to their efficiency in converting sunlight to electricity. The most common type of solar panel is the silicon solar cell, which has an efficiency of around 15%. Silicon solar cells are used in most commercial solar power plants.

The second most common type of solar panel is the thin-film solar cell, which has an efficiency of around 12%. 

The third type of solar panel is the concentrating photovoltaic (CPV) cell, which has an efficiency of around 10%. CPV cells use mirrors or lenses to concentrate sunlight onto a small area of high-efficiency solar cells.

The fourth type of solar panel is the multi-junction solar cell, which has an efficiency of around 40%. Multi-junction cells are made from multiple layers of different materials, such as gallium arsenide (GaAs) and indium arsenide (InAs).

Finally, there is the organic photovoltaic (OPV) cell, which has an efficiency of around 5%. OPV cells are made from carbon-based materials, such as polymers and small molecules.

Advantages and disadvantages

Types of solar cells: semi-cut solar cell technology

As with any technology, there are advantages and disadvantages to using semi-cut solar cells. Some of the advantages include:

• Increased light absorption – Since the metal contacts are not covering the entire surface of the cell, more light can be absorbed, leading to increased efficiency.
• Lower cost – Semi-cut solar cells are less expensive to manufacture than traditional solar cells.
• Increased flexibility – Semi-cut solar cells can be used in a variety of applications due to their thinness and flexibility.

Some of the disadvantages of semi-cut solar cells include:

• Reduced durability – The exposed metal contacts are susceptible to corrosion, which can reduce the lifespan of the cell.
• Shading issues – If shading occurs on one part of the cell, it can affect the entire cell’s output.
