What colour of the visible light spectrum striking your solar cell are being absorbed by it?...
What colour of the visible light spectrum striking your solar cell are being absorbed by it? What would happen to its power efficiency if a filter of the same color as the anthocyanin was placed over your cell? The solar cell is a TiO2 solar cell which utilizes raspberries.
Homework Answers
Solar cells are made out of N-type and P-type semiconductor material that use the visual light spectrum to generate electricity. Solar radiation with wavelengths of 380 nm to 750 nm (violet to red) strike the material with enough energy to knock electrons from their weak bonds and create an electric current

Which of the following best explains what happens as photons of visible light are absorbed by dye molecules? Certain electrons in the dye molecule move to a higher energy level, with the difference in energy between the lower and higher energy levels being the same as the energy of the absorbed photons Certain chemical bonds in the dye molecules begin to bend and stretch with the difference in energy between the lower and higher vibrational states being the same as...
