FREQUENTLY ASKED QUESTIONS

WHERE ARE SOLAR CELLS MANUFACTURED?

The production of solar cells occurs in various countries, with leading manufacturers often situated in regions rich in technology and infrastructure. Notable players include China, the United States, Germany, and Japan. The manufacturing process involves several stages, beginning with the extraction of raw silicon, which is then purified. Once purified, silicon is formed into ingots and sliced into wafers. These wafers undergo doping processes to create p-n junctions, essential for the photovoltaic effect. Subsequently, the cells are assembled into modules to produce solar panels.

China stands out as a dominating force in solar cell production, creating a significant percentage of the global supply. The country’s investment in solar technology and favorable government policies have catalyzed expansion in this industry, enabling unprecedented growth. Conversely, other regions also contribute to solar panel manufacturing, establishing diverse suppliers and fostering local economies. The ongoing competition and technological advances in these countries play an instrumental role in shaping the international solar market.

HOW DO PHOTOVOLTAIC CELLS WORK?

Photovoltaic cells function through the photovoltaic effect, which involves converting light directly into electricity. The operation of these cells centers around semiconductors, typically silicon, which are treated to create two distinct layers: p-type (positive) and n-type (negative). When sunlight strikes the surface of a photovoltaic cell, it excites electrons in the semiconductor material, prompting them to move. This movement creates an electric current as free electrons flow from the n-type layer to the p-type layer, establishing voltage.

The generated electricity can either be used immediately or stored in batteries for later use. The effectiveness of this process is influenced by the intensity of light and the angle at which sunlight hits the cells. Various factors, such as temperature, shading, and degradation over time, can also affect the overall performance and efficiency of solar cells. Continuous innovation in manufacturing techniques and materials aims to improve the efficiency of photovoltaic cells while making them more cost-effective for consumers.
