The annual electricity bill, running into thousands of rupees a month, is huge. Ordinary citizens are distressed to cover this cost with the income received. The option of solar energy is definitely convenient to get rid of these costs. The problem is that since it cannot be stored, what to do at night? This question arises. But now the experts have found the answer. A team of engineers from Australia has found a solution to this problem. So now even at night it can be used to generate electricity from solar energy.
This may seem strange at first, but it is true. There are many substances that can be used to generate electricity by reversing the process of conventional solar panels. It generates electricity when heat escapes from the material at night. A team of engineers from Australia has demonstrated this principle.
This technique is also commonly used on glasses that appear in the dark of night. So far, the prototype of this new technology has generated very little energy and may soon take time to develop as an alternative energy source, but if this technology is combined with current photovoltaic technology, it can use the energy obtained from solar panels. heated during the day after cooling at night.
How this system works In the photovoltaic process, sunlight is artificially converted into direct electricity. This is the most popular way to use solar energy. In this sense, the thermodynamic process works in a similar way, taking advantage of the thermal energy that goes into space through infrared waves. When heat flows through the atoms of any substance, the electrons begin to emit electromagnetic radiation in the form of infrared waves. This process can lead to slow power generation of very low capacity.

The role of special diodes can be used to generate power very slowly at very low capacity. This requires a device with only one direction of electron flow, called a diode. In it, electrons accumulate when heat is lost. The researchers used a diode made of mercury cadmium telluride (MCT), which is used to capture infrared light. It is unknown at this time what he will do after leaving office.
MCT photovoltaic detectors emit a density of 2.26 milliwatts per square meter at temperatures up to 20 degrees. So even water cannot be boiled for coffee. Current thermodynamic diodes are giving very little power. But this technology could be made more efficient in the future. But discovering this technology was a real challenge.
Work is currently underway to use the planet’s cooling process as a source of low-energy radiation, one of which was done in this study. Increasing the capacity of this technology can eliminate the need to replace or remove the battery. This is just the beginning.
