Does this circuit look right?

I'm building a solar powered iphone charger and i just want your opinions on it as far as if i put it together right. If not please suggest how i could do it differently thanks

Circuit ---->

It looks funny to me. What is in the outlet box? A solar panel has 2 outputs. One is the positive voltage and the other is the negative voltage.

No, learn how to draw a real schematic.

From what I can tell, you have a battery, a solar array, a light bulb (labeled resistor) and an AC outlet all in series.

this will not work. First of all, you do now want an AC outlet in the circuit, too dangerous. Second, you need a real resistor of the proper value, not a light bulb.

On second look, that AC outlet is not actually an AC outlet, but is intended to be a USB voltage source. To charge a cell phone, you need regulated 5 volts at at least 1/2 amp. A 1.5 volt battery will not supply 5 volts, with or without a resistor. The solar array could, with a bright sun, generate 5 volts, but the voltage will vary and the current may not be enough.

Looking at your numbers, apparently you intend to take the 4.5 volts, add the 1.5 volts with the battery and subtract 1 volt via the light bulb. This won't work. First, the 4.5 volts out of the solar panel is actually dependent on the sun and could be anywhere from zero to 5 volts. Second, a resistor will not subtract a fixed voltage. The voltage to the cell phone has to be a constant 5 volts.

Yes, I'm sorry, that will not work for all the reasons billrussell42 said.
I would suggest that what you need are solar cells in series and parallel configurations to provide enough voltage and current respectively (power) to connect that to a power regulation circuit, to charge your iphone's battery.

You do not need a lightbulb nor another battery other than what is in your iphone already.

For the regulation circuit, I would try a voltage regulator chip of the same voltage of the iphone's charger port (probably USB right? Which would make it a positive 5 Volt regulator.) Like a 7805 voltage regulator should work. I think Radio Shack still sells these. You would need pin outs for the chip, but pinouts are available online or on the back of the Radio Shack package.

You would still need to know the voltage and amperage of each solar cell so that you can configure them to produce the right power for your regulator.

I wouldn't bother with a capacitor, because you are just charging something; there shouldn't be really any ac ripple to contend with.

I wouldn't even bother with current limiting resistors because if you have the voltage right with the voltage regulator and the iphone is meant to be charged using that port, then no worries; the iphone will only take from that voltage the current that is required to charge the phone.

Circuit design can be fun. However, please, test your outputs first and check the input and output polarities before connecting them! Do not destroy your iphone. :0:)
