Some basic information about solar cell
Solar cells are devices which convert solar light energy directly into electricity and function by the photovoltaic effect. Photo- means light and -voltaic means electrical current or electricity (light-electricity). A solar cell provides direct current (DC) electricity that can be used to power DC motors and light bulbs among other things. Solar cells can even be used to charge rechargeable batteries so that electricity can be stored for later use when the sun is not available. The fully charged batteries are portable energy that can be used whenever and wherever they are needed.
Solar cells provide DC electricity similar to batteries however, batteries differ because they operate through a process known as an electrochemical reaction. This process will provide an electrical current (electro-) from a chemical reaction (-chemical) that occurs inside the battery. When you hook up a motor to the battery, also known as a load, the reaction begins and electrons flow as shown in the picture: "Battery Circuit". Direct current (DC electricity) is different from the alternating current (AC electricity) that is used to power the TV, refrigerator, and other appliances in your home however, DC can be converted to AC when needed.
Battery Circuit (large image)
Solar cells produce DC electricity from light. Sunlight contains packets of energy called photons that can be converted directly into electrical energy. You can’t see the photons but they hit the cell and produce free electrons that move through the wires and cause an electrical current as shown in the picture: "Solar Cell Circuit". The electrical current is the electricity that powers the motor. Although you can't see the photons you can see the light and you can assume that the amount of photons hitting your solar cell is related to the amount of light hitting your solar cell. A greater amount of light available means a greater amount of photons are hitting your solar cell and the more power you get from it.
Main technical parameters about solar cells
Cell Thickness
An optimum silicon solar cell with light trapping and very good surface passivation is about 100 µm thick. However, thickness between 200 and 500µm are typically used, partly for practical issues such as making and handling thin wafers, and partly for surface passivation reasons.
Doping of Base
A higher base doping leads to a higher Voc and lower resistance, but higher levels of doping result in damage to the crystal.
Reflection Control
(front surface typically textured)
The front surface is textured to increase the amount of light coupled into the cell.
Emitter Dopant
N-type silicon has a higher surface quality than p-type silicon so it is placed at the front of the cell where most of the light is absorbed. Thus the top of the cell is the negative terminal and the rear of the cell is the positive terminal.
Emitter Thickness
A large fraction of light is absorbed close to the front surface. By making the front layer very thin, a large fraction of the carriers generated by the incoming light are created within a diffusion length of the p-n junction.
Doping Level of Emitter
The front junction is doped to a level sufficient to conduct away the generated electricity without resistive loses. However, excessive levels of doping reduces the material's quality to the extent that carriers recombine before reaching the junction.
Grid Pattern.
The resistivity of silicon is too high to conduct away all the current generated, so a lower resistivity metal grid is placed on the surface to conduct away the current. The metal grid shades the cell from the incoming light so there is a compromise between light collection and resistance of the metal grid.
Rear Contact.
The rear contact is much less important than the front contact since it is much further away from the junction and does not need to be transparent. The design of the rear contact is becoming increasingly important as overall efficiency increases and the cells become thinner.
- Q: Can solar cells be used in disaster relief or emergency response situations?
- Yes, solar cells can be used in disaster relief or emergency response situations. Solar cells provide a reliable and renewable source of energy that can be used to power critical devices and infrastructure such as communication systems, medical equipment, lighting, and water purification systems. They are easily deployable, independent of the electrical grid, and can operate in remote areas, making them ideal for emergency situations where access to traditional power sources may be disrupted.
- Q: What is the impact of hailstorms on solar cells?
- Hailstorms can have a detrimental impact on solar cells. The physical force of hailstones can cause damage to the surface of the solar panels, leading to cracks, scratches, or even complete destruction. This damage can impair the performance and efficiency of the solar cells, resulting in reduced energy production. Additionally, if the hailstones are large enough, they can break or dislodge the cells from their mounting structure. Therefore, it is crucial to protect solar panels from hailstorms through the use of appropriate shielding or protective measures to ensure their longevity and optimal functioning.
- Q: Are solar cells durable?
- Yes, solar cells are generally durable. They are designed to withstand various environmental conditions such as heat, humidity, and extreme temperatures. Additionally, most solar cells are made with materials that have a long lifespan and are resistant to degradation. However, proper maintenance and protection are necessary to ensure their longevity.
- Q: How do solar cells perform in areas with frequent tornadoes?
- Solar cells can perform well in areas with frequent tornadoes as long as they are properly designed and installed to withstand extreme weather conditions. While tornadoes can potentially damage or destroy solar panels, advancements in technology have made solar cells more resilient. Additionally, solar panels can be reinforced or mounted securely to minimize the risk of damage. It is important to consider the specific location and design of the solar installation to ensure it can withstand tornadoes and other severe weather events.
- Q: What is the impact of solar cells on wildlife?
- The impact of solar cells on wildlife is generally minimal and beneficial. Solar cells produce clean energy without emitting harmful pollutants or greenhouse gases, reducing air and water pollution that can negatively affect wildlife habitats. Additionally, solar energy infrastructure typically occupies a small footprint and can coexist with wildlife habitats, allowing animals to continue their normal behaviors. However, there have been some concerns about the potential for bird collisions with solar panels and the disruption of desert ecosystems during large-scale solar installations. Overall, compared to traditional energy sources, solar cells have a much lower impact on wildlife and contribute to a more sustainable future.
- Q: How are solar cells integrated into building designs?
- Solar cells can be integrated into building designs in several ways. One common method is to install solar panels or modules on the roof, which capture sunlight and convert it into electricity. These panels can be mounted on top of the roof or integrated into the roofing material itself. Another approach is to incorporate solar cells into windows or building facades, creating solar glazing that generates electricity while still allowing natural light to enter the building. Additionally, solar cells can be integrated into shading devices such as awnings or louvers, providing both energy generation and sun control. Overall, integrating solar cells into building designs allows for the efficient utilization of renewable energy and reduces dependency on traditional power sources.
- Q: Can solar cells be used in powering autonomous vehicles?
- Yes, solar cells can be used in powering autonomous vehicles. Solar energy can be harnessed using solar panels and converted into electrical energy to power the vehicle's battery or directly power its systems. This allows for a sustainable and renewable source of energy, reducing the reliance on fossil fuels and increasing the vehicle's range and efficiency. However, it's important to note that the amount of energy generated by solar cells may not be sufficient to fully power the vehicle, so it is often used in combination with other energy sources like batteries or fuel cells.
- Q: Can solar cells be used for powering shopping malls?
- Yes, solar cells can be used for powering shopping malls. By installing a sufficient number of solar panels on the rooftops or in parking lots, shopping malls can generate renewable energy to meet a portion or even the entirety of their power needs. This can help reduce dependence on fossil fuels, lower electricity costs, and contribute to a more sustainable and environmentally friendly operation.
- Q: What are the main components of a solar cell?
- The main components of a solar cell are the semiconductor material (usually silicon), which absorbs sunlight and generates electrons, the metal contacts that allow the flow of current, and the transparent cover that protects the semiconductor from environmental factors while allowing sunlight to reach it.
- Q: Can solar cells be used in museums?
- Yes, solar cells can be used in museums. They can provide renewable energy to power museum exhibits, lighting, and other electrical systems, reducing the reliance on traditional energy sources and minimizing the environmental impact. Additionally, solar cells can be integrated into the design of the museum building itself, enhancing its sustainability and showcasing a commitment to renewable energy.
