vertically, using no fuel but only energy generated from the Sun (assume full sunshine is present without obstructions)?

Everything that can be done, has already been done before, we are just paying the price to "transfer the knowledge" from "those who have done it before", it must be paid ON TIME, BEFORE TIME, EVERY TIME Without fail, even the knowledge to "BREATHE" must be repaid that is why we are repaying it as CO2, the knowledge to "THINK" must be repaid also but we dont know how.
A balloon goes up with nothing but hot air enclosed in a circular or oval shaped container. If we make a helicopter in that shape it will go up also, but where are the controls to steer it in the proper direction and to increase and decrease the speed?

Yes only scale models can work. For real copters it is dangerous to try and safety proceedures does not allow such copters. U can try scaled down models with a battery and a solar panel. However it is difficult to put in air for longer time. Try experiments yeild results.

I think it is possible
Use capacitors to store the energy, then once full you can discharge at a rapid enough rate to possibly get a rotor turning. Caps weigh much less than batteries though you won't be able to fly anywhere.
Prolly best to use the suns power to spool up a flywheel that doesn't have the drag like a rotor does, then engage the clutch on the main rotor and use the stored engergy to lift off momentarily.
Either way you aren't flying, you are taking off momentarily.

I recently designed a photovoltaic control circuit designed to increase the KVA rating of a solar cell. My circuit design could potentially be powerful enough to lift a helicopter, depending on the surface area of the photovoltaic cells.

You don't need a helicopter in the shape of a balloon. We have those, they are called airships. They could use batteries and solar cells, but it is cost prohibitive.

get a lawn chair a bunch of helium balloons and a b.b.gun it has been done/// do not drop the b.b.gun like the last guy at 17,000 feet

Not with our current technology.

No. If you do try, don't try in Wales - not much sun.
