6 FAQs about [Can optical disks absorb heat from solar energy to generate electricity ]
Can a Blu-ray Disc help solar cells absorb sunlight?
The Northwestern researchers have demonstrated that a Blu-ray disc’s strings of binary code 0s and 1s, embedded as islands and pits to store video information, give solar cells the near-optimal surface texture to improve their absorption over the broad spectrum of sunlight.
Can Blu-ray discs be recycled into solar panels?
While it’s certainly appealing to think about recycling our Blu-ray discs directly into more efficient solar panels, a more realistic approach might be to use the mass-production infrastructure that’s already in place to create optical media that’s adapted to improving solar cell performance.
Can a Blu-ray Disc improve light absorption?
An interdisciplinary research team has discovered that the pattern of information written on a Blu-ray disc -- and it doesn’t matter if it’s Jackie Chan’s “Police Story 3: Supercop” or the cartoon “Family Guy” -- works very well for improving light absorption across the solar spectrum. And better yet, the researchers know why.
Do Thermophotovoltaic cells generate electricity from infrared light?
Just as solar cells generate electricity from sunlight, thermophotovoltaic cells do so from infrared light. Now, in a new study, scientists have revealed thermophotovoltaic cells with a record-high conversion efficiency of more than 40 percent, better than the average turbines used to generate power in the United States.
Can Blu-ray patterned solar cells be used for light trapping?
The overall broadband absorption enhancement of a Blu-ray patterned solar cell was measured to be 21.8 percent, the researchers report. “In addition to improving polymer solar cells, our simulation suggests the Blu-ray patterns could be broadly applied for light trapping in other kinds of solar cells,” Sun said.
How do solar panels work?
Solar panels perform more efficiently when sunlight is spread evenly over the cells’ surface, allowing for more equal exposure. Normally, expensive, pre-made fabrications using “quasi-random nanostructures” are used to diffuse the sunlight to achieve maximum efficiency.
