What determines the output voltage in a solar cell?

When a photon hits an electron from the N-Semiconducter, flows into a hole in the p-Semiconducter. This creates current in the system. But what distinguishes the current tension? V = IR indicate the resistance is the only variable … But I is constant, depending on how electrons are called free … and if there are infinite resistance then V is infinite, so we just created and a source of infinite energy (P = IV) (just kidding, of course). So what is the determination of stress?

The rate at which electrons are ejected the N-semiconductor (and by this I mean the literal number of electrons passing a fixed point in the circuit) is a measure of current. Resistance is also independent is fixed. This gives V = IR, I is the independent variable, dependent on V, R is of course a constant. So we have that V is directly proportional to I, thus increasing I increase V. To increase I can increase the cell surface, or change the internal properties of the materials in the cell (ie the N-semiconductor material used). Now, as you probably want a practical way to make this happen, I would say try to increase the cell surface. Furthermore, it is likely that has an upper limit for the material used which gave a maximum current can pass as a fixed area, so if you use a hypothetical cable without resistance, still be faced with a maximum voltage produced. Hope this helps.
