Transistor solar cell

[Dominic Arthur]

with the exception of transistor 2n3055, can any high current power transistor TO 3 been used for solar cell?

so it seems. probably the 2n3055 is used the most as it has a large surface area and is cheap

The power transistor is likely to

1) have plated the front surface with emitter metallization,
limiting incoming photonic absorbtion

2) locate the significant (C-B) junction deep in the silicon
where short wavelengths' freed charge may not be
seen

Produce electricity? Sure. Produce useful, let alone cost
effective, amounts? Not likely.
