Scientists have created solar panels that can work at night

Solar panels — it is an intermediate element that converts sunlight into energy, having a very simple but very effective design

They allow you to independently produce energy, which contributes to sustainable development as much as possible, thereby protecting the planet from further cruel treatment of it. Interest in the use of solar energy is growing every year.

Although at first solar energy was collected exclusively during the day, models are beginning to appear that work also at night thanks to accessories or additional technologies.

Thanks to research conducted by Stanford University, a group of experts has found a way to modify the design of ordinary solar panels in such a way that they can also generate electricity at night.

The goal of this research was to demonstrate that semiconductors can be used to modify the functions of silicon solar panels so that they can generate power at night, not just during the day.

For this, it is necessary to use a thermoelectric generator, which has a system capable of converting temperature changes into electricity, and which would function as an intermediary between the photovoltaic elements and the surrounding air, generating the electric current necessary for its use and operation.

According to the tests carried out as part of this study, the scientists found that the thermoelectric generator produced only 1% of the current generated by a conventional solar panel during daylight hours, while this increased to 40% at night.

The research results are undoubtedly promising, although scientists say the system is not yet ready for mass production.

The proven power density is very interesting in night lighting conditions, as the researchers say: "Due to the long lifetime of the thermoelectric generators, our proposed configuration can have lower long-term maintenance costs compared to storage batteries. The demonstrated power density is already interesting for use in night lighting. Our development can also power sensors in remote locations, reducing the size or eliminating the need for rechargeable batteries.
