S. Korea develops technique to recycle discarded solar panels into high-performance solar cells:

Researchers have developed a non-destructive technique to recycle discarded solar panels to create high-performance solar cells. The technique will become crucial in a few decades when solar panels that are currently being used are discarded after their operational life of about 20 years.

A solar panel is a photovoltaic module made of materials such as glass, aluminum, silicon and copper. It uses sunlight as a source of energy to generate direct current electricity. A solar cell is a black mirror-like electrical device that is the key component of a solar panel. Techniques have been researched to maximize the efficiency of recycling solar panels.

The state-run Korea Institute of Energy Research (KIER) said in a statement on August 19 that a technique developed by its research team led by Lee Jin-seok enables the recycling of solar panels. The institute said the new technique can recycle both undamaged and damaged panels to achieve up to 100 percent retrieval rate of glass components. About 80 percent of other materials can be retrieved and recycled into high-performance solar cells.

    This is the development that has been needed to make solar panels truly a "green" source of energy. until now the panels had to be mostly made from materials that had a carbon foot print to aquire and process into raw materials.

    That is of course if this new process can be done with energy from other carbon neutral/negative sources.

      Not inherently. I mean, you can still reduce the silicon oxide to silicon without carbon.

        You seem to be assuming that energy has zero carbon footprint.

        If that was the case, we wouldn't even be having this discussion in the first place. You've just *moved* the problem, and probably made it larger in the process.

            The good news is that it's now over unity. Even being pessimistic, it's at least 4, and some might claim it's now up to about 10 or so.

          1. There'll be a transient period while the assumption doesn't hold true, but we are getting there
          2. zero carbon footprint is not necessary the end goal. A sustainable equilibrium level of greenhouse gasses, good enough for humanity living on Earth, is.

            That works right up until some dumbfuck know-it-all bloviates a bunch of bullshit into some policymakers ass about how he knows everything and we have perfect information in the domain, which turns into polity and precipitates a black swan event and causes an untold catastrophe.

    It takes 20 years for the panels to lose some power and they only lose a fraction. Much better than batteries. I'd be cool buying used panels. Who is throwing these things out? Unless you're talking a tiny panel, those house sized 35v ones hold up well.
