I worked on this technology in my first masters a couple of years ago, so of course I'm biased but I believe the encapsulation to protect from all kinds of degradation will be critical and as you say because of their less intensive processing they will be the future once the kinks are ironed out (not literally). Recyclability may be a more difficult problem but again there is headway being made on that front then toxicity and waste become much less of a problem. On the other hand with much cheaper materials there could be less incentive to recycle as there won't be much profit made from it. Perhaps we'll need government support of it.

In other words, how much energy does it take to make it. And for the most part (for now), that energy is comming from oil or natural gas, or coal.

Good intro on it. Regardless of what types, one of the larger expressed arguments against solar panels is the end of life treatment, fears of toxic waste - where it's going to go, water tables etc... maybe another video to make centers on the recycling of solar panels, potential mechanisms to do it high and low volumes, at low costs etc as part of the total life cycle. Same issue with batteries, which seem further ahead right now with companies like Redwood Materials and Li-cycle well into the game. Somehow, there needs to be a collection mechanism that bundles them up in a way that they can fill railroad cars or trucks with them and take to designated sites for reduction to primary materials again. I'd like to hear who is planning for an going after that sort of issue, what they expect to see as recovery and lost in process. thx.

Now, lithium dominates the battery market. Of course, I also remember the technologies that didn't work so well. NiCd, for example.

I live in the northern US (Michigan's Upper Peninsula on the shores of Lake Superior). While the sun does shine, there is more of an abundance of wind for the better part (many many months) of the year. Having a wind turbine that the neighbors won't complain about would be a boon for the generation of electricity and ... more importantly ... HEAT !

@agsystems8220 2 роки тому

Depends on who is using it, and whether it is integral to a structure. In a dedicated solar farm switching out every module every 2 years could easily be viable if the cost is low enough and they are designed to make the job easy. Even if they were roof mounted, switching them out could be viable. If you have to tear off the whole roof, not so much. I'm not a fan of the window idea for that reason too, but replacing the blinds every 2 years wouldn't be that big a deal. Either way, I think the biggest barrier currently is the lack of good energy storage, not the difficulty of collection. The next barrier is the cost of the inverters to get solar energy to the grid. Even if the cells themselves were free, it would only reduce the cost of a system by 50% because the electronics are already half the cost.

Spotweld cracks it, solder comes right off. The pure forms are actually available relatively cheaply (under 100USD for a stack of 50 10cm x 5cm rectangles) even on e-bay but at least 80% will have fracture on arrival. These have a GREAT potential but as you mentioned, very few companies are packaging them but at a huge drop in efficiency. Right now the packaging is the biggest issue. Also one of the craziest advantage of perovskite cell is that it works fairly well when the piece is broken.

@insAneTunA 2 роки тому

Those machines for separating valuable materials from electronic waste already exist. They use mechanical force, and shaker decks, and water with additives, magnets, and all kind of different methods to separate the materials. They crush and mill everything to a fine powder, and while traveling through the machine various processes separate the materials in various stages. For example they can separate the lighter particles from the heavier particles by using a solution of water with soap that attaches to the lighter particles and that makes the lighter particles float, and then they skim of the lighter particles, and the heavier particles move on to the next process, and so on. It is one machine that does all the separation until all the various materials are separated from each other as much as possible. They do that because on average they can recover more gold out of one ton of E waste compared to a ton of gold ore. And then there is also the other valuable materials that are recovered from the E waste. Such as platinum and other precious metals, but also copper and less valuable materials, but that are still useful and profitable. And yes that machine consumes a lot of energy, but compared to the energy that is used to mine and refine new materials it is absolutely only a fraction of the total energy that is used for mining and refining new materials.

@insAneTunA 2 роки тому

I know that a Duch company is very good at building these machines, but it is not a wide spread knowledge, because they don't really want to show how those machines work, because they don't want too many people to know that E waste is actually a very valuable product. I once watched a documentary about recycling E waste, and they even stated that at some point in time there will be so much E waste on a yearly bases that for some materials it will no longer be needed to mine for it in nature, if we make the processes that makes it possible to recover the valuable materials as efficient as possible with an infrastructure that makes it possible to do that. Meaning that it should be easy for people to offer their broken products to a recycling station, and so on. In my country you can offer your broken product to the delivery guy that brings you the new device that you bought online. Given the fact that it is a similar device. So if your TV is broken and you buy a new one they take your old TV if you want that. It is not obligated for the consumer to do that, but it is a service, and the delivery guy is obligated to offer that service.

Welll. Very cool I think tech that directly harvests solar energy into electricity has a constant issue, it always suffers from UV damage and electron migration ect, so a thin film tech like perovskite could see more widespread use even with a reduced lifespan because it can be easier to replace, becoming a simple chore done every few years with proper engineering. Something like a roller system with a stabilized paper leader just tape the new roll on, and crank the rollers till the old roll is off. And that can give it an large market advantage if the costs are low enough and if there is a core trade in to further reduce costs and reclaim the gold used. So perhaps it is far to soon to tell the future but in any future it seems this tech has a future at least in some applications.
