LED bulbs are a worthy alternative to incandescent bulbs, they have advantages in comparison with those bulbs that we are used to using in our everyday life. First of all, it is worth noting that LED bulbs have a longer service life, on average 10 years (an incandescent bulb works on average 3-4 months), in addition, there is a significant saving of electricity (LED - 10W, incandescent bulb - 75W) and do not forget about the environmental side. But the cost of LED bulbs significantly exceeds the price of conventional or energy-saving bulbs, so most consumers refuse to use them and choose energy-saving or conventional incandescent bulbs.
At the University of Florida, scientists have announced a revolutionary method for producing LEDs that will make the cost of such light bulbs much lower and, therefore, more affordable.
If the price of LED and incandescent bulbs becomes the same, the latter will most likely simply disappear from our lives.
Florida scientists noted that the new manufacturing method involves one layer, instead of the 4-5 layers used in modern LEDs. Applying a combined organic/inorganic material in one layer will allow the LED bulb to retain its efficiency, but will make its price much lower. In addition, today, applying layers requires high temperatures, with the new method it will be possible to do this at normal temperatures.
It is worth noting that researchers have been using this material for a long time (about 3 years), the material has been used for some time to make solar panels, but Professor Zhebin Yu's group was the first to use this material to make single-layer LEDs.
Traditional LED lamp manufacturing technology involves high temperature processing and expensive substrates to achieve high power, all of which led to the high price of the LED bulb.
The first organic light-emitting diode (OLED) bulbs were processed in a single layer at low temperatures, but gradually more layers were added and amorphous silicon substrates began to be used, which increased the efficiency and also the price of the finished product.
Professor Zhebin and his colleague Junqiang Li claim that the new method of producing LEDs they have developed will be a real scientific breakthrough. To produce the LED, they will need organometallic perovskite halide, which can be easily applied at normal room temperature, and the cheapest glass substrates can be used. The layer is fixed at only 600C.
The researchers also noted that to create the structure, it will be necessary to combine an organic and active inorganic polymer, which will replace the complex process of obtaining a multilayer structure. As a result, the production process is significantly lower in cost and is quite technological.
In their paper, the team of experts claims that their technology will make LED lights more affordable by reducing the number of layers.
