What is a thin film design?

thin film design is the production technique of storing very thin layers at the base or substrate material. The process can be used for paints, electronic parts or solar cells to create electricity from light. A thin film describes the process of adding a very fine amount of product to the recurring layers, not necessarily how strong the finished product is. Over time, semiconductors and devices on a solid state were available, allowing electronics to use light small circuits. Until the 21st century, it led the continuing improvement of electronic circuits to devices with smaller sizes and more computing capacity. The design of a thin film is important for its ability to use small amounts of expensive raw materials to produce circuits at relatively low costs. The growing market at the beginning of the 21st century was the development of flexible circuits. Instead of having to use rigid circuits, developers could now create electronic parts on very thin flexible plastics. The market that benefited from this improvement was the solar elEctre.

Solar panels at the beginning to mid -20th century were heavy, rigid panels made of solid glass and thick layers of electricity generating materials. In time, he led a thin film design to stiff panels with a much lower weight that shortened the installation and expenses. In addition, thin films allowed the placement of solar panels in portable calculators, radios and mobile phones or chargers at low cost. At the end of the 20th century, solar cells were first made on a plastic film, allowing the panel to be inverted for storage or installed as the outer surface of a building or vehicle.

Energy efficiency, measurement of the solar light is transformed into electricity was low in early solar samples. Electricity made of solar panels was usually stored in batteries that had their own efficiency limitation. It was important to maximize the energy efficiency of the solarThe design and design of the thin film allowed efficiency to increase over 20 percent at the beginning of the 21st century, expecting further improvements because new materials were tested.

In the 21st century, solar thin films used either a mixture of crystalline and non -crystalline or amorphous silicon. Crystalline silicon can be compared with sand, where molecules have a solid, regular structure. The amorphous material is like glass where molecules are more accidental with different physical and electrical properties.

At the same time, metal mixtures have been developed for solar cells that could create electricity from light. Copper Indium Gallium selenid (Cigs) and Cadmium Telluride (CDTE) were two technologies used as alternative to silicon. These metals, although toxic in some cases, were firmly fixed in the design of a thin film and at that time they did not consider themselves environmental risks. In all cases, manufacturers have chosen a specific design to create the highest efficiency per unit to obtain market inouhodu.

Some products can be sprayed similarly to paint on a glass or film base. Alternating layers of electrically conductive and non -conductive materials can create electronic circuits. Another process for storing thin films is spraying, where the material evaporates and has an electric charge where the base material with the opposite charge is attracted. Laser light can be used to evaporate materials to be stored on the substrate. Plasma, high energy electrical discharge, can be used to transmit materials in some design of thin films.
