Solar Energy

Do you do any work for your self?

I've just been looking at your previous posts, try CR4 search and Google first.

You're going to need to be a little more clear on how you're going to go about this project. There's a lot of variations in materials and techniques for going about making a solar cell, and within those variations you have to decide what kind of balance you want to strike between efficiency and cost.

thank you

i want to make chemical cells i am looking for a simple way to build it.

thanks for your information.

The more "basic" of the solar cells use silicon. Here's a link to help you learn a bit about them: http://www.madehow.com/Volume-1/Solar-Cell.html

The more recent solar cells however involve utilizing thin films of material such as semiconductors, organic material, or polymers to absorb and convert the sunlight.

If you're looking to make any kind of solar cell just to make a computer renewable, start with silicon wafers. By my understanding, they seem much easier to "make" without any prior knowledge of how they work.

thank you so much for your advice i will do the best

This is the rule to which I referred in my PM's to you. I pulled it up for another OP who was obviously doing homework, too.

I'm done scolding you, this is just for clarity:

• Do your own homework. CR4 is not a homework cheat site. While some here might relish the opportunity to sharpen up old rusty skills by working the homework problem, consider this and consider it well. If you cheat on your homework by using someone else's answers, you are only cheating yourself, because the purpose of any homework or other college assignments is to help you learn - by practice, repetition, and self-discovery. (thanks STL Engineer)

Good Luck.

Dear Fatima,

What kind of cells do you plan on making. As far as I know there are two types of solar cells.

1) Mono crystalline. (Shorter life span, Cheaper, Easily available)

2) Multi crystalline. (Expensive, Longer life span and less maintenance cost).

Now that you know what kind of cells there are you can start by deciding what you want to do. Check the details of each type on the internet and how they can be made. The rest is up to your efforts. Good bye and Good luck.

Regards,

DG EE

tank you so much

i will research for this types

good luck

Fatma ,Ur graduation project is on application . so don't confuse urself with solar cell design .simply decide the wattage capcaity of the load ; no of hrs load has to be run ; decide the autonomy ; and then simply decide the module capacity
