Solar cells, also known as photovoltaic cells, are the building blocks of solar modules that convert sunlight into electrical energy. The process that enables this conversion is based on the so-called photovoltaic effect. In this article, we will explain the basics of how solar cells work, their components and the physical principles behind them.
How is a solar cell constructed?
A typical solar cell consists of the following main components: Semiconductor material: In most cases, the solar cell is made of silicon, a semiconductor capable of absorbing sunlight and converting it into electricity. There are two types of silicon solar cells: monocrystalline and polycrystalline. Monocrystalline cells have a higher efficiency, while polycrystalline cells are more cost-effective. p-n junction: This is the boundary layer between two differently doped semiconductor layers, the p-layer (positive) and the n-layer (negative). The p-layer is doped with boron, which gives it a positive charge, while the n-layer is doped with phosphorus, which gives it a negative charge. Front contact and rear contact: These metal contacts conduct the generated current. The front contact consists of thin metallic lines that allow the light to pass through, while the back contact covers the entire back of the cell. Anti-reflective coating: This coating minimizes the reflection of sunlight and ensures that more light can penetrate the cell.
How do solar cells work?
The operation of a solar cell is based on the photovoltaic effect, which comprises the following steps: Light absorption: When sunlight hits the solar cell, the semiconductor material absorbs the photons (light particles). These photons transfer their energy to the electrons in the semiconductor material. Electron-hole pairs: The energy of the photons knocks electrons out of their atomic bonds, creating free electrons and so-called "holes". A hole is the place where an electron was previously and represents a positive charge. Separation of the charge carriers: The p-n junction creates an electric field that drives the electrons to the n-side and the holes to the p-side of the solar cell. This separation prevents the electrons and holes from recombining immediately. Current flow: When the solar cell is connected to an external circuit, the electrons flow through the external circuit from the n-side to the p-side to fill the holes created. This electron flow generates a direct current (DC) that can be used to power electrical devices or stored in batteries.
What does the efficiency of solar cells depend on?
The efficiency of a solar cell depends on various factors, including the material quality, the manufacturing technology and the conditions under which the cell is operated. Modern commercial solar cells achieve efficiencies of 15-22%, with research and development aimed at further increasing this efficiency.
What advantages do solar cells offer
Solar cells have a wide range of applications, from small devices such as calculators and watches to large solar power plants that supply entire cities with electricity. The most important advantages of solar energy include Renewable energy source: Solar energy is virtually inexhaustible and available everywhere. Environmentally friendly: solar energy produces no harmful emissions and helps to reduce CO2 emissions. Economical: Once installed, operating costs are low and solar energy can bring significant cost savings in the long term. Solar cells are a fascinating technology that makes it possible to convert the sun's energy into usable electricity. Ongoing research and development is continually improving the efficiency and affordability of solar cells, making them an increasingly attractive option for sustainable energy generation. By relying on solar energy, we can make an important contribution to protecting the environment and at the same time reduce our dependence on fossil fuels.
How long is the service life of a solar system?
The service life of a solar system, especially solar modules, is usually between 25 and 30 years. This figure is based on the warranties and performance guarantees that most manufacturers offer for their products. Here are some important points that influence the lifespan and performance of a solar system: Quality of solar panels: High-quality solar panels from reputable manufacturers tend to be more durable and offer better performance over time. Installation: Professional installation is crucial for the service life of the system. Errors during installation can lead to damage that shortens the life of the modules. Maintenance and care: Regular maintenance and cleaning of the solar modules can extend their efficiency and service life. Contamination such as dust, leaves or bird droppings can impair performance. Environmental conditions: Extreme weather conditions, such as hail, strong winds, snow or salty air in coastal areas, can stress the modules and other components of the system. Ageing and degradation of performance: Over time, the performance and efficiency of solar modules decrease due to degradation. Most manufacturers guarantee an output of at least 80-85% of the original rated output after 25 years.
What are the components of a solar system?
Solar modules: As already mentioned, solar modules have a service life of around 25-30 years. Inverter: The inverter, which converts the direct current (DC) generated by the solar modules into alternating current (AC), has a shorter service life than the modules. Most inverters need to be replaced after 10-15 years. Battery storage: If a solar system is equipped with battery storage, the service life of the batteries varies greatly depending on the type of battery (e.g. lead-acid, lithium-ion). Lithium-ion batteries generally have a service life of 10-15 years. Mounting systems and cabling: These components can also last over 25 years, provided they are made of corrosion-resistant materials and have been properly installed. A well-maintained and high-quality solar system can therefore function for at least 25 to 30 years, with the solar modules often being the longest-lasting components. Regular maintenance and professional installation are crucial to maximize the life of the system and ensure optimal performance. After this time, the performance of the system may decline, but the modules will generally continue to generate electricity, albeit at a lower efficiency.
Energy storage for solar energy: Battery storage for homeowners and businesses
As solar installations become more widespread, homeowners and businesses are faced with the challenge of using and storing surplus solar energy efficiently. Energy storage systems offer the perfect solution to maximize self-consumption and minimize dependence on external energy suppliers. Energy storage systems make it possible to store surplus solar energy during sunny hours and retrieve it when needed - for example in the evening or on cloudy days. This not only leads to a more stable and sustainable energy supply, but also to considerable cost savings. In addition, energy storage systems contribute to grid stability and support the transition to a more environmentally friendly energy future.
For homeowners, integrating an energy storage system into their solar installation means greater independence and optimized use of the solar energy generated. Companies benefit from a reliable and cost-efficient energy supply that reduces operating costs and improves their environmental footprint. Invest in the future of your energy supply and discover the benefits of energy storage systems for your solar installation. Benefit from innovative technologies and take an important step towards sustainability and energy independence.
