The voltage will be double that of one dry cell. The current will be that of one dry cell.
The panel itself produces DC and if it is connected to mains electricity it needs a separate converter to change the current to AC.
It's connected in series with the load.
The current, if connected to a voltage source that can supply the needed current to (R1+R2) R3, will be unchanged. If the source cannot supply the needed current, the terminal voltage will decrease, which will change the current flowing through R1 and R2.
In electrochemistry, overvoltage is synonymous with overpotential. Look up overpotential instead of overvoltage to get details of what it is. Basically, it is a potential that develop because of limited reaction kinetic. It works to reduce the voltage of the electrochemical cell. Think of it like this. For a given redox reaction pair that represents a chemical cell, it has a theoretical voltage determined by thermodynamics. This is typically called the open cell voltage. It's the maximum voltage that you could harness out of this reaction if you were to make this into a battery. That is all very good and all except for the little detail of reaction kinetics. In reality, you don't ever get the maximum voltage at open cell. Once current start flowing, limitations on rate of reaction at the cathode and anode develop. Reactions are not infinitely fast. Once you start the reaction, the region near the electrodes are depleted of ion species as they are oxidized or reduced into and out of the electroloyte. It takes time for more to diffuse from the bulk to the solution to the electrode/electrolyte interface. Now your reaction rate is limited. This limitation will show up as a potential, the overpotential, at the electrode. It acts to reduce the potential available to you across the entire cell. If your open cell potential of a batttery was say 2 volts, you may find a severely rate limited reaction to generate 1.9 volts of overpotential at the electrodes as you try to draw current out of the battery. When that happens, your cell actually only gives you 0.1 volts, not 2 volts. What I described above is called concentration overpotential. There are other sources of overpotential. It is much beyond the scope of Y:A to describe it. However, the phenomenon of overpotential in an electrochemical cell is a consequence of reaction kinetics. There are other concepts like equilibrium exchange current density and the use of the Tafel plot when you delve into the topic of electrochemical cells. These are things that must be considered in addition to the thermodynamic open cell potential when a cell starts to draw a current. The best batteries will be constructed out of a system in a way as to have high exchange current density and minimum overpotential. So as you draw current from the cell, you don't find yourself with vastly diminished voltage. It's ability to do work will not be self-limiting as you put it in a device that draws current.

battery
An electrochemical cell, which is sometimes called a battery.
The Anode in electrochemical cell has negative charge (-ve).
They are called the electrodes or terminals. The parts of a cell where current leaves and enters the cell. The cathode is the positive, the anode is the negative.

In a electrochemical cell or a battery there are two electrodes and an electrolyte. Chemical reaction occurs between the electrodes and the electrolyte which causes one of the electrodes to be positively charged and the next one to be negatively charged. The differences between the two electrodes creates voltage. When the battery is now connected to a circuit it makes a current.
A biological fuel cell is another term for a microbial fuel cell, a bio-electrochemical system which drives a current by mimicking bacterial interactions found in nature.
