Understanding Photovoltaic Cells

Photovoltaic cells, also known as solar cells, are the essential components of a solar panel that convert sunlight into electricity. These cells are made from semiconductor materials such as silicon and function as a result of the photovoltaic effect. Photovoltaic cells are widely used in various applications, ranging from small electronic devices to large-scale solar power plants. This section will provide an in-depth understanding of photovoltaic cells, their principles, types, and factors that affect their efficiency and performance.

Principles of Photovoltaic Cells

The photovoltaic effect is the basic principle that governs the functioning of a solar cell. This effect occurs when photons from sunlight hit the surface of the cell, transferring their energy to the electrons within the semiconductor material. As a result, these electrons gain enough energy to break free from their bonds and become free electrons, creating an electric current.

A typical photovoltaic cell consists of two layers of semiconductor material, with each layer having different electrical properties. The upper layer, referred to as the ‘n-type’ layer, has an excess of electrons, while the lower layer, known as the ‘p-type’ layer, has a deficit of electrons. When sunlight hits the cell, the photons’ energy excites the electrons and creates a voltage potential between the two layers.

To harness this generated electricity, metal contacts are placed on both sides of the cell. When an electrical load is connected between these contacts, the electrons flow from the n-type layer through the load and back into the p-type layer, creating an electric current. This process is known as the photovoltaic effect.

Types of Photovoltaic Cells

There are several types of photovoltaic cells available in the market, with each type offering different levels of efficiency, cost, and suitability for various applications. Some common types of solar cells include:

  1. Monocrystalline Silicon Cells: These cells are made from a single crystal of silicon and offer high efficiency due to their uniform structure. They have a distinctive dark color and rounded edges. Monocrystalline solar cells are the most efficient and expensive option, with efficiency levels ranging from 15% to over 20%.

  2. Polycrystalline Silicon Cells: Also known as multicrystalline cells, these are manufactured from multiple silicon crystals and have a less uniform structure than monocrystalline cells. They have a blue color and square-cut edges. Polycrystalline cells are less expensive than monocrystalline cells but have lower efficiency levels, typically between 13% and 16%.

  3. Thin-Film Solar Cells: These cells are made by depositing thin layers of photovoltaic materials onto a substrate, such as glass, plastic, or metal. Common materials used in thin-film solar cells include amorphous silicon, cadmium telluride (CdTe), and copper indium gallium selenide (CIGS). Thin-film solar cells have low efficiencies, ranging from 10% to 12%, but are lightweight and flexible, making them suitable for applications where weight and flexibility are essential.

  4. Perovskite Solar Cells: An emerging technology, perovskite solar cells are made from a group of materials called perovskites. These cells have shown great potential in terms of efficiency, and some laboratory tests show that they can achieve efficiencies of over 20%. However, they are still in the early stages of commercial development due to issues such as stability and long-term performance.

Efficiency and Performance Factors

The efficiency of photovoltaic cells refers to the percentage of sunlight that is converted into electricity. Several factors affect the efficiency of solar cells, including:

  1. Material quality: The semiconductor material’s quality directly impacts photovoltaic cell efficiency. High-quality, defect-free materials can better absorb and convert sunlight into electricity.

  2. Temperature: Solar cell efficiency generally decreases as temperature increases. This is because higher temperatures cause increased electron movement, which can result in more losses within the cell.

  3. Reflection losses: Sunlight that is reflected off the cell’s surface, rather than being absorbed, is lost energy. To minimize reflection losses, manufacturers often use special coatings or textures on the solar cell surface.

  4. Electrical resistance: As electrons move through the cell and conductive materials (such as metal contacts), they encounter resistance, reducing the solar cell’s output. Minimizing these resistive losses is essential for achieving higher efficiency levels.

  5. Light-induced degradation (LID): Some solar cells, especially those made from silicon, can experience a decrease in efficiency in the initial period after exposure to sunlight. This phenomenon is called light-induced degradation, and it can lead to a reduction of up to 3% in efficiency.

Apart from efficiency, other performance factors should be considered when selecting photovoltaic cells, such as the lifespan, manufacturing processes, and environmental impact.
