What is a photovoltaic movie?
Our sun offers a potentially huge reserve of clean, free, endless energy. Everything that is needed to convert solar energy into usable electricity is a photovoltaic (PV) system. Most people are familiar with photovoltaic cells or have seen them earlier, for example, on solar calculations, emergency brands and call boxes and other places. As PV technology has advanced, a new type of PV material began to be used, namely a photovoltaic film. This film has the same function as the traditional PV cell, but with a construction that makes it flexible and much more versatile. This means that production costs are significantly decreasing compared to. This is especially interesting for those who consider PV systems an alternative source of energy.
In the past, it was exactly the cost of the necessary materials that made PV cells so expensive, and therefore impractical as a means of electricity production on a large scale. The development of a photovoltaic film is a very important progress toward the viability of ROZsáho energy production PV systems.
Another remarkable point is that a photovoltaic film can actually generate more electricity than traditional PV cells under certain conditions. They can also work better under high temperature conditions, are lightweight and are not nearly so fragile because no glass is used in their construction.
Traditional PV cells are made using two layers of different types of silicon crystals that have different electrical properties. These silicon layers allow electrons to flow when they come into contact with photons, a subatomical wave of a similar particle that is being designed for us as light. On both sides of the two -layer silicon structure, a pad and a contact grid are then placed. Because silicon is a highly reflective material, an anti -reflective coating is added. The entire structure is then inserted into a robust frame with a glass cover and on the back are placed positiveand negative electrical terminals.
The photovoltaic film is designed using the same basic technique, although alternative materials allow these systems to be much thinner and do not need a glass cover. Many scientists and other people who are familiar with PV systems assume that the photovoltaic film will complement and complement traditional silicone PV systems without replacing older systems or to obsolete.
