No matter how sustainable, eco-friendly, and clean sources of energy they are, conventional solar panels require a large setup area and heavy initial investment. Due to these , it’s hard to introduce them in urban areas especially neighborhoods with lots of apartment blocks or shops. But now researchers have created transparent solar panels which they claim could be used as power-generating windows in our homes. In order to generate power from sunlight, solar cells on a solar panel are required to absorb radiation from the sun. Therefore, they cannot allow sunlight to completely pass through them. Transparent luminescent solar concentrators is capable of selectively absorbing invisible solar radiation including infrared and UV lights, and letting the rest of the visible rays pass through them. In other words, these devices are transparent to the human eye but still absorb a of the solar light which they can then convert into electricity.
