Solar cells and their teachnoleadges

The history of solar cell development is briefly outlined, and the properties of the sun and solar radiation are reviewed. Properties of semiconductor materials that are important in the design and operation of solar cells are reviewed. The physical mechanisms involved in the generation and recombination of excess carriers are discussed and the basic equations of device physics are given. Both the dark and illuminated properties of p-n junctions are analyzed. Energy conversion efficiency limits are discussed for the photovoltaic process as well as the effects of various nonidealities on efficiency. Techniques for measuring the efficiency of photovoltaic devices are also described. The standard technology for making silicon solar cells is reviewed, and improved silicon cell technology is discussed. Considerations relevant to the detailed design of silicon cells are discussed. Several alternative device concepts are outlined and the structure and properties of solar cells made on some of the more developed alternatives to single-crystal silicon are discussed. Concentrating systems and photovoltaic systems components and applications are described. The design of stand-alone, residential, and centralized photovoltaic power systems are discussed. 

Solar cells and their applications

Multiple solar cells in an integrated group, all oriented in one plane, constitute a solar photovoltaic panel or solar photovoltaic module. Photovoltaic modules often have a sheet of glass on the sun-facing side, allowing light to pass while protecting the semiconductor wafers. Solar cells are usually connected in series and parallel circuits or series in modules, creating an additive voltage. Connecting cells in parallel yields a higher current; however, problems such as shadow effects can shut down the weaker (less illuminated) parallel string (a number of series connected cells) causing substantial power loss and possible damage because of the reverse bias applied to the shadowed cells by their illuminated partners. Strings of series cells are usually handled independently and not connected in parallel, though as of 2014)individual power boxes are often supplied for each module, and are connected in parallel. Although modules can be interconnected to create an array with the desired peak DC voltage and loading current capacity, using independent MPPTs (maximum power point trackers) is preferable. Otherwise, shunt diodes can reduce shadowing power loss in arrays with series/parallel connected cells.

 

Q: How do solar cells handle voltage fluctuations in the grid?
Solar cells do not directly handle voltage fluctuations in the grid. Instead, the grid itself, through the use of inverters and other control devices, manages and stabilizes the voltage fluctuations to ensure compatibility with solar cells and other energy sources connected to the grid.
Q: How do solar cells perform in areas with frequent earthquakes?
Solar cells can perform well in areas with frequent earthquakes, as they are designed to withstand a certain level of structural stress. However, the installation and mounting of solar panels should be done with proper engineering considerations to ensure their stability during seismic events. Additionally, regular inspections and maintenance may be required to address any potential damages caused by earthquakes.
Q: How do solar cells perform in mountainous regions?
Solar cells can perform well in mountainous regions, especially if they are strategically placed to maximize exposure to sunlight. However, the performance of solar cells can vary depending on the altitude, slope, and orientation of the panels. It is important to consider factors such as shading from nearby peaks or trees, as well as the potential for snow cover during winter months. Overall, with proper planning and installation, solar cells can effectively generate electricity in mountainous regions.
Q: How do solar cells handle high winds or hurricanes?
Solar cells are designed to withstand high winds and hurricanes due to their robust construction and installation techniques. The panels are securely anchored to rooftops or mounted on sturdy frames, ensuring they can withstand strong winds. Additionally, solar panels are tested and rated for wind resistance, with most systems being rated to withstand wind speeds of up to 140 miles per hour. Therefore, solar cells are designed to handle high winds and hurricanes with minimal damage or risk of detachment.
Q: Can solar cells be used in residential communities?
Yes, solar cells can be used in residential communities. In fact, they are increasingly being adopted by homeowners as a sustainable and cost-effective alternative to traditional energy sources. Solar panels can be installed on rooftops or in open spaces within residential areas, harnessing sunlight to generate electricity for individual households or even for the entire community. This not only helps reduce reliance on fossil fuels but also enables homeowners to save on energy costs in the long run.
Q: How do solar cells impact the local economy?
Solar cells have a positive impact on the local economy as they create jobs, stimulate investment, and reduce energy costs. The installation, maintenance, and manufacturing of solar cells require skilled labor, thus creating employment opportunities within the community. Additionally, the growth of the solar industry attracts investments in infrastructure and research, fostering economic development. Moreover, solar energy helps lower electricity bills for businesses and households, freeing up funds that can be spent on other local goods and services, thereby boosting economic activity.
Q: Can solar cells be used in desert regions?
Yes, solar cells can be used in desert regions. In fact, desert regions are ideal for solar energy generation due to their high levels of solar radiation and clear skies. The availability of ample sunlight and vast open spaces make deserts well-suited for large-scale solar power installations, such as solar farms or concentrated solar power plants. Additionally, the arid climate in deserts minimizes the risk of cloud cover or rain interfering with solar energy production.
Q: How are solar cells manufactured?
Solar cells are manufactured through a multi-step process that involves the production of silicon wafers, the creation of a p-n junction, the addition of anti-reflective coatings, and the assembly of electrical contacts.
Q: Can solar cells be used in agricultural irrigation systems?
Yes, solar cells can be used in agricultural irrigation systems. Solar-powered irrigation systems can effectively harness the energy from the sun to power water pumps and provide a sustainable and cost-effective solution for irrigation needs in agricultural settings. This technology reduces dependence on traditional energy sources and helps conserve water resources while promoting environmentally friendly practices in agriculture.
Q: Can solar cells be used in powering RVs and campers?
Yes, solar cells can definitely be used to power RVs and campers. In fact, many RVs and campers are now equipped with solar panels to generate electricity for various appliances and systems onboard. Solar power provides a sustainable and environmentally-friendly option for off-grid living, allowing RV and camper owners to have a constant source of clean energy while being able to travel and explore remote locations without relying solely on traditional power sources.
