I don't think anybody wants to do his homework for him.
For free.

Now every SPAM robot has his e-mail address. He will receive millions (maybe billions?) of SPAM e-mails.
And lots of viruses and spy-ware.

Wow, that link's covered just about everything wrong that can be wrong.
IIRC CdS photocell is very slow. Solar cells are slow too. Actually IIRC laser pointers are limited in their speed too. I seem to recall that red LEDs acting as receivers (yep LEDs actually act as photovoltaics too) were actually the winner for speed, even though the tiny signal requires a preamp.

What do you intend to transmit?
