Can optical discs generate electricity from solar energy

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.

Do CD solar panels produce electricity?

While the energy output is minimal, CD solar panels can still generate a small amount of electricity under direct sunlight. This electricity could power small devices or provide a supplemental power source for low-energy applications. But!

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.

Are CDs useful for solar energy experimentation?

Even though CDs have some features that make them potentially useful for solar energy experimentation, more features are needed to create a highly efficient or practical solar panel. A CD’s shiny, reflective surface can help concentrate sunlight onto a solar cell or photovoltaic material, potentially increasing light absorption.

Can a 30W photovoltaic solar panel be built with 15 CDs?

In a third video “ Homemade 30W Photovoltaic Solar Panel ” the creator proposes building a panel using 15 CDs. This design seems to try to mimic a traditional photovoltaic cell, with the CDs fulfilling the role of the silicon semiconductor, and aluminum foil as the contacts on the top and bottom layers.

Can you make a photovoltaic array from old compact discs?

Spoiler: Of Course Not! You may seen videos go viral, with tens of millions of views, that apparently show people creating photovoltaic arrays by wiring coils around grids of old compact discs (or even just adhering aluminum foil strips across them). Hey, they look all shiny metallic and solar-y, so they should be able to generate power, right?
