Hi Bordodynov, I am not sure if it will make much sense to continue this discussion.
I have got the impression that we both start from different views - and this will cause some misunderstandings.
Nevertheless, some short comments.
* Simulation results can never reveal which parameter (voltage or current) will be the cause of some effects.
These programs use formulas and calculate relationships forward and backwards.
But in this discussion - as far as I understand - we are discussing the question of cause and effect.
* When you speak about photodiode currents - this current will flow within a closed current loop.
Don`t you think that there will be an E-field driving the carriers which form the current? And how is this E-field produced?
What is your answer to the fact I have mentioned that photocells are combined in series for producing a larger voltage?
* Quote: "your statement about "Vbe-uncertainty (0.6 or 0.7 volts)" is wrong" .
I think, it is by far not sufficient simply to state that something is wrong - without any comment or justification.
I really do not understand such a "funny" comment.
It may be interesting to read about your early transistor experiments, but what do you want to show me?
Of course, you can assume (assume !) that it would be possible to "inject" a current into a circuit node (and calculate correspondingly), but that is not the physical truth - it is just a helpful "rule of thumb" !
A current cannot be "injected" - a current is always the RESULT of an applied voltage.
* Clear and simple question: Can you show me one or more circuit examples, which can be explained with BJT-current-control only? Up to now, nobody from the "current-control party" was able to present such a circuit.
On the other hand, I have no problems to show how and why it is the base-emitter voltage that determines the collector current.
(And that is the reason for my position which you call "obsession").
