I have a project where i have to include solar cells andpiezoelectric transducers in an umbrella.
They will be used to transform solar energy and energy from rainrespectively into electrical energy. (stored in a lithiumbattery)
I would like to know how i should build up the circuit. Asin:
1. should i connect the solar cells in series?
2. How do i connect the piezoelectric transducers? what type ofrectifying diode i need for this experiement.
3. What calculations i can use to show that the energy harvestedby the piezoelectric transducers will be very little?
4. What calculations i can then use to show that to have moreenergy i make use of solar cells?
