FAQS on solar panel solar cell
以下是根据要求创建的5组英文FAQs问答（使用HTML富文本形式）：Q: What is the difference between a solar panel and a solar cell?
A: A solar cell is the basic unit that converts sunlight into electricity, while a solar panel consists of multiple interconnected solar cells enclosed in protective materials. Solar cells produce 0.5-0.6 volts each, whereas panels combine them to generate usable voltage. Panels include additional components like glass covers and frames for durability.
Q: How is cell efficiency measured in solar cells?
A: Cell efficiency measures the percentage of sunlight converted to electricity, calculated by dividing electrical output power by incident solar energy. Standard testing uses AM1.5 spectrum at 25°C. High-efficiency cells like monocrystalline silicon achieve 20-25% efficiency under lab conditions.
Q: Why do solar panels have lower efficiency than individual solar cells?
A: Panels have lower efficiency due to interconnection losses between cells and additional layers like encapsulants. Glass covers and anti-reflective coatings reduce light absorption. Temperature effects and wiring resistance also contribute to 2-5% lower efficiency compared to isolated cells.
Q: What factors influence solar cell efficiency the most?
A: Key factors include semiconductor material (silicon/perovskite), photon absorption capabilities, and electron-hole recombination rates. Surface texturing and anti-reflection coatings boost light capture. Temperature coefficients also critically impact performance, with efficiency dropping 0.3-0.5% per °C above 25°C.
Q: How are solar cells interconnected within solar panels?
A: Cells are wired in series using conductive ribbons to increase voltage output. This creates strings that are then paralleled to boost current capacity. Busbars collect the combined electricity, which exits through junction boxes. Advanced panels use half-cut cells to minimize shading losses.
