Our existing solar panels arent really efficient; they are just able to convert up to about 20 percent of the suns energy into electricity. If solar panels were more effective, much smaller panels could make the same amount of electricity, and would not claim as much land.
Currently, solar panels rely on expensive materials like silicon and include elements that can be harmful, including l ead and cadmium– in many states solar panels are considered harmful waste when its time to dispose of them. Saha is confident that her solar panels will be mostly plant-based particles and other products that are relatively prevalent like copper, making them much easier to recycle when the time comes.
Lahari Saha, a researcher at the University of Maryland, Baltimore County, is establishing a novel method to enhance the performance of photovoltaic panels. Her research study includes leveraging plants capability to convert sunshine into chemical energy through biological molecules such as chlorophyll, which are excellent at recording sunlight and transforming it to energy.
Present photovoltaic panels are inefficient and include hazardous products, a different approach that harnesses plant particles like chlorophyll could cause enhancements.
Our current photovoltaic panels arent really efficient; they are just able to transform up to about 20 percent of the suns energy into electrical energy. As an outcome, to create a lot of electricity, the panels need a great deal of area– often leading forests to being lowered or farms to being replaced by solar. If solar panels were more effective, much smaller sized panels might make the same quantity of electrical power, and wouldnt claim as much land.
To make solar panels that are more effective, Lahari Saha, in the lab of Professor Chris D. Geddes at the University of Maryland, Baltimore County, is working to make electricity in a special way– by harnessing plants abilities to transform sunlight into chemical energy utilizing biological particles, like chlorophyll, that excel at soaking up sunshine. Saha will present her deal with Wednesday, February 22 at the 67th Annual Biophysical Society Meeting in San Diego, California.

Their objective is to utilize biological molecules to make electrical power that can then be harvested and used to power devices or stored in batteries for later usage. The procedure includes leveraging particles fluorescence. “Any sort of molecule that fluoresces, produces light. If we thrill the fluorophore, it can transfer its energy to metal nanoparticles, and if the particles are close sufficient to each other, they will knock off electrons and produce existing,” Saha discussed. The procedure is not simply limited to particles that fluoresce, Saha discussed, they simply need to have high absorption of light such as chlorophyll, beta carotene, or lutein. Each of these is easy and fairly inexpensive to obtain from plants
The other advantage of this kind of fluorescence-based solar panel is that it would be easier to recycle. Presently, solar panels depend on pricey products like silicon and contain components that can be toxic, consisting of l ead and cadmium– in many states solar panels are thought about contaminated materials when its time to get rid of them. But Saha is confident that her solar panels will be mainly plant-based molecules and other products that are fairly common like copper, making them much easier to recycle when the time comes. Plus, by selecting materials with greater longevity, she hopes the solar panel will last longer prior to it is time to get rid of them.
However Sahas leading goal is to make a solar panel thats more effective, “so it does not have as big of a footprint,” she stated. She hopes her smaller sized solar panels will enable farms to optimize food production over generating energy, and will keep forests protected.
