    Why in this short circuit geometry can I not sense a photocurrent?

    Thanks! I don't have the datasheet now. But I posted more detailed explanation of the situation on the above post.

    Why in this short circuit geometry can I not sense a photocurrent?

    I think I should explain why I come up with the problem. Now I am measuring photovoltaic material. I deposite electrode top and bottom of the PV material, and check the resistance with a multimeter. It shows over Giga ohms order (Out-of-range for multimeter). Running the PV measurement on that...

    Why in this short circuit geometry can I not sense a photocurrent?

    I'm really thank you for your answer. But I cannot draw the circuits as you requested. Could you give me some hint to understand the phenomenon as circuit V,R(internal resistance),r(shorted resistance), and ampere meter? I keep drawing the circuit like the below picture. it shows that the...

    Why in this short circuit geometry can I not sense a photocurrent?

    Hi, I'm wondering why shorted circuit geometry like figure 2 did not sense photocurrent? Even if the the circuit composed like 2, I guess that by the Kirchhoff's Law, voltage should apply to the ampere meter and photocurrent should be sensed. But in real experiment, I found that shorted circuit...
