A way to increase photovoltaic cell efficiency with fiber optics? A way to increase photovoltaic efficiency using fiber optics?
One of the claimed inhibitors of efficiency was the band gap of materials which contrasts to that of a photon. My idea is a way to possibly mitigate this loss by increasing the frequency of the electricity being generated(?) and taking it directly to coil. 
In a glass fiber from fiber optics, light bounces back and forth many times before finally exiting out the other end of the fiber optic thread. 
What if you were to manufacture a fiber optic thread so that it has a thin copper coil embedded in it that would have a staggered patterned coating on bare copper of n type and p type silicon? Think n,p,n,p,n,p etc for the nano coating facing the light source. The copper winding would be encapsulated at this point to prevent energy leakage. The copper coil would not be tightly wound and would leave space for some of the light to reflect to the other parts of coil. 
The nano silicon of p and n types would directly transfer the photovoltaic charge to the copper coil and it would remain homogenous to the coil. A secondary coil would be used (not coated with anything save for an insulator) to transfer the energy elsewhere. So basically this is induction.
Would the back and forth motion of electrical charges be sufficient for this to work? 
Would the induction frequency occur near the speed of light? 

 A: Your device is hard to visualize, it would help if you drew a picture so we can see exactly how it works in theory. I'm not sure if your device would work, but I can explain some additional concepts that may help you put together something that will.
Lossy band gaps...
When a photon is absorbed by a semiconductor, you can see loss of energy if the photon has a little too much energy than required, and the electron decides not to use it all. For example, Silicon has a band gap of about 1.1eV, if you shoot a 1.2eV photon at it, the electron will be excited to a state with energy of 1.1eV to 1.2eV higher than the state it was in in the valence band. A new photon will be created with the unused energy. 
Cure: Tandem Solar Cells.
If the photon does not have enough energy to be absorbed via band gap, it will go straight through the material. One can design a stack of photo-voltaic cells that first absorbs only high-energy light, then slightly lower photon energies until you reach the photovoltaic cell which can excite electrons from low-energy light. This way, the high-energy photons are absorbed first with high efficiency, then the next highest energy photons are absorbed and so on.

A: What you looking for is cooper pairing 
https://en.wikipedia.org/wiki/Cooper_pair
Means that a single photon trapped can atract electrons from the walls of the tube and create enegy (better creating heat) ? Is that what you looking for?
