Making homemade solar cells is not that hard, provided that you know the process. Many people who are interested in building solar cells at home, simply use very ineffective ways, and as a result they build a large cell, which cannot power anything more than a small LED. That’s not what we are talking about here – we want to learn how to make homemade solar cells, which can give you about 100-200Watts per square meter. That is perfectly possible, and can be done cheaply. Read on.
Homemade solar units fall into two categories – semiconductor ones, and ones based on natural dyes. The second type can be constructed extremely cheaply, for about five dollars per a hundred watt. The drawback is that people often have trouble sealing the cell properly, and making the cell airtight, and as a result it dries up in a couple of months, which results in a drop of power. That can be easily resolved though. The semiconductor solar cells are another alternative, and certain semiconductors can be produced very easily at home, and used to make a solar panel, which are then connected into a panel. The whole procedure is very straightforward and easy to do, even by inexperienced people, and that’s the reason why green energy, and energy from the sun are becoming extremely popular today. Most people are building cells, in order to power up their laptop, or other small appliance.
If you want to power your home, that is also possible, but it’s going to take a bit more work, as you should build storages for the electricity – the sun is only available during the day. Another option, is to build a very simple circuit which switches to mains power during the night – that will still save you a lot of money on electricity, and is very interesting project to take on. So, learning how to make homemade solar cells is easy and cheap, provided that you find it interesting enough, to start actually building the panels!
