product description

 

Currently, polysilicon is commonly used for the conducting gate materials in semiconductor devices such asMOSFETs; however, it has potential for large-scale photovoltaic devices.The abundance, stability, and low toxicity of silicon, combined with the low cost of polysilicon relative to single crystals makes this variety of material attractive for photovoltaic production. Grain size has been shown to have an effect on the efficiency of polycrystalline solar cells. Solar cell efficiency increases with grain size. This effect is due to reduced recombination in the solar cell. Recombination, which is a limiting factor for current in a solar cell, occurs more prevalently at grain boundaries,

Q: Hello Yahoo, I am doing another one of my wacky inventions however I need something that will give me 2V of power!I don't want to connect loads of AA batteries into a battery holder as this shall run out quickly and become expensive in the long run, I don't want to carry around a big car battery either.I have been searching around on OKorder .uk and found some Solar-Powered 2V Trickle Chargers. These say they shall work on cloudy days (which is perfect as the majority of the time that is all we get!) but could I use it as an independent power source?If I attached the thing I want to run to the solar panel will it supply it with 2V of power?
How many amps will you need? Remember v x a = power. The way those trickle chargers work is by sacrificing some amperage to get up to 2 volts. If you can invent closer to ~3V range that solar cells naturally produce thing will likely work better. A sign or a light that doesn't need a lot of power will work. Automobile battery packs might take a month to charge. Solar-Powered 2V Trickle Chargers are used mostly to keep things like boat batteries in storage from discharging, not to charge them.
Q: How do solar panels affect the appearance of a home or building?
Solar panels can have a positive impact on the appearance of a home or building by adding a modern and eco-friendly aesthetic. While they may alter the traditional appearance slightly, the sleek and futuristic design of solar panels can often enhance the overall visual appeal of the structure.
Q: Do solar panels require regular inspections or maintenance checks?
Yes, solar panels do require regular inspections and maintenance checks to ensure optimal performance and longevity. These inspections typically include monitoring the panels for dirt, debris, or shading that may reduce their efficiency, as well as checking the electrical connections and wiring for any issues. Additionally, ongoing maintenance such as cleaning the panels and replacing any faulty or damaged components is essential to keep the system operating efficiently.
Q: Hi. I have been looking into getting solar panals but I only want them for one room. See, we're expanding the house by adding a basement, the basement isn't going to be that big but we wanted to have solar energy for the basement only. Could anyone give me a rough estimate on the cost of solar panals for my basement?
As Tex said, you have no idea whats involved. Start by looking into some sites that explain how they work and whats involved before asking how much on a small room. And how do you add a basement but not a main floor? and where is the basement roof?
Q: if so, would it be possible to make (or remake) an organism that could subsist off of sunlight and external heat like plants?
Plants and algaes and cyanobacteria already exist. What exactly do you want?
Q: please no dumb answers and list where you got the info.Also how much does it cost to install solar panels for a regular sized house?
Short version is that the sunlight knocks electrons loose from a semiconductor panel, and those loose electrons generate an electrical current. The solar panels have lots of cells arranged in series parallel to get to a higher voltage (usually 2 or 24 volts) and current. This is sent to charge batteries under the control of a charge controller. The voltage from the batteries is sent to an inverter that converts the 2/24 volts to 20/240 VAC for household usage. .
Q: I know what they do and how they work, but at this point they're expensive, don't always produce enough electricity as needed, and can't be used when there's no sun, as in half the day. Wouldn't wind power seem so more efficient? Or if they do use solar panels, how about putting them in the desert. But I really believe that research money should go to fusion generators since that's the future and the answer to our problems. Which is best in your opinion?
i think that they are effective, even tho they cost heaps to get installed, i think that they are worth it. They dont require any effort to operate and use natural sunlight that turns into energy that people use everyday. they may be an eye sore but think of how much they are helping the earth and they are a great alternitave to fossil fuels (which are running out anyway), the only problem that i think they would have would be in winter when there isnt much sun on a few days. but other than that they are great
Q: Is it as simple as buying the panels, an inverter and plugging it into a wall-socket, assuming it would just send power back into the outlet and supplement my house's electrical usage, or... Is it not that simple?Remember, I'm talking about a SMALL system, and I don't care how little power it'd make, or how uneconomical it would be.
How to tie small solar panel system into my house's electircal system? It's very complicated. Just for starters, if you plugged your solar panel into your electrical outlet, you would probably see smoke and fire, not electricity. Of course anything CAN be done. But this one is truly unfeasible at the consumer level. The only way to send power back into a live system is to synchronize the phase voltages. In your case you would require the solar panels, a battery backup system, a voltage inverter and some type of industrial synchronizer (probably a generator) so you could sync your inverter output to the utilities output. Solar is still more of a standby or supplemental type power at this time. The easiest way is to supplement your hot water by using solar panels to heat water rather than create electricity. If money was not much of an option then you could theoretically run your whole house without the need for any synchronization but have a gasoline or diesel generator to keep your battery pack topped up when needed.
Q: Can solar panels be used to power a camping trip?
Yes, solar panels can be used to power a camping trip. They are an excellent source of clean and renewable energy, allowing campers to charge their electronic devices, power lights, refrigerators, and other camping equipment. Solar panels are portable and can be easily set up in a sunny location to harness the sun's energy during the day and store it in batteries for use at night. They provide a sustainable and eco-friendly solution for powering camping adventures.
Q: So I'm trying to figure out what to ask for my birthday because its one of the few times I can get stuff for no reason, like stuff I don't normally go to the store to buy. (i dont go to the store to get much at all anyway).Anyway, I'm interested in solar panels and led and electronics and i was wondering if there is anything not over expensive that would be cool. Some things I'm interested in:solar, wind, water energyGadgets (multitools, swiss army knives)Vibram fivefingersdrawingmaking stuff (duct tape wallets, stuff out of altoids containers)basically technology and outdoors-gear stuffoh and im 6 turnin 7 male.
solar panel is expensive, but small solar panel is not expensive, for example, 5w solar panel, solar light also not expensive led light also not expensive. i am not sure about other stuff that you said
