You would need a 90%+ efficient Solar cell + A superconducting DC Motor

Not impossible within the laws of physics. But we are a long way away.

Even at 100% efficiency with the most advanced solar cell you won't squeeze more than 100W/sqft at peak hours... Because that's all you get from the sun.

At 100% efficiency, a solar cell would make on average 1KW per Sq Meter or 92watts per Sq F. You also wouldn't be able to see it (it wouldn't reflect any light) and it would be vert cold (all energy (Including heat) is converted to electricity)

My point exactly... 92W/sqft (maximum in ideal conditions) is simply NOT ENOUGH.
A small panel will NEVER fully charge a car, even if through some miracle you'd reach 100% efficiency.
Even the wimpy Chevy Volt has a 18kWh battery. For the middle of US you have a low of below 4kWh/m^2/day energy in winter, in ideal conditions (panel adjusted for month). That means at least 50sqft of ideal panels from sunrise to sunset, perfectly adjusted for the season. And no clouds.
