This is for my science project and i cannot figure it outWe assumed that blue light shining on a solar panel would give off the higher volt reading because it has the shortest wavelength and the highest energy, but it was actually the lowest. Why does this happen? Im very confused And cant find the answer anywhere.... ，thank you!!
It is based on what the solar panel is made out of. Many of them will generate electric into the NIR region.
Surely the highest volt reading will result from the wave with the largest amplitude, wavelength irrespective? You'd need to know the amplitude of the wave AFTER leaving the colour filter, since different chemicals and pigments in the filter would naturally affect the resulting wave in different ways.
Likely there will be at least a small change in the no load volts. The short circuit current will be different and the watts output will be different. Connect an amp- meter to the panel with or without a to 00 ohm resistor in series with the amp-meter and you will see different amounts of current for different colors. You do however need to adjust for the amount of light falling on your solar panel. Possibly you can use a exposure meter or a bolo meter as reference. Neil
