Light shines on a heterojunction solar cell, exciting the electrons in it. These excited electrons cause an electric current to flow when they break free. This way, the cell produces electricity for use. Reducing Surface Recombination. Heterojunction cells are good at lowering surface recombination, a common problem.
$begingroup$ Actually a current will flow if you connect a conductor to any voltage, through simple electrostatics. Not noticable at most voltages, but see what happens when you touch a peice of metal to a 100,000kV line, even in a vaccumm with no earth, a sizeable current will flow to bring the metal to the same electrostatic charge.

I have always been confused when it came to how much charge does a battery charge. Let''s say, a phone battery: It says 1900 mAh @3.7 v. Now i know it goes up to 4.2v, but those 1900 mAh are available in the 2.5v ( cut off voltage i think) - 4.2v area or the 1900mAh are available in the entire 0v-4.2v, meaning that some of the battery s energy remains unused, right?
When the starter is turned on, the 12 Volt (V) car battery sends current to the starter motor. At this instant the resistance (R) of the motor is just the resistance of the copper wire that makes up the stator and rotor coils and is therefore low (less than 0.05 Ohms). The initial starting current (I) is therefor high (greater than 240 Amps ...

The current in the circuit is going to be 4.4mA or 4.2mA. Not only have you reduced the total current going through the circuit from AMPS to a few mA, you''ve also reduced the variability current as well. You''ve reducing the current''s sensitivity to slight changes in the diode characteristics, the source voltages, etc. Hope that helps.
For a typical 6f22-form factor battery it is something 2-20 ohm for a new battery at room temperature. It gets higher as the battery gets discharged, rises with discharge current and gets a bit lower for moderately elevated temperature (say, ~50C). The initial short-circuit current for such a battery is ~1 Ampere.
Even at 8A, the battery will be flat after half an hour. And be aware that lead-acid batteries don''t like being left flat. Once run down, they should be recharged as soon as possible, or they may be permanently damaged. *1C is a current numerically equal to the amp-hour rating of a battery. So for an 8Ah battery, 1C is 8A.
In many devices that use batteries -- such as portable radios and flashlights -- you don''t use just one cell at a time. You normally group them together in a serial arrangement to increase the voltage or in a parallel arrangement to increase current.The diagram shows these two arrangements. The upper diagram shows a parallel arrangement.The four batteries in …

ANY battery does not just throw amperage or current; it will first discharge as much current as physically possible based on its chemistry and chemical reaction, and then what limits this discharged current is the resistance of the circuit it is connected to.
