Consider the circuit in Figure 2 with a source delivering power to a load consisting of Resistor R₂ (R₁>R₂) and unknown impedance Z. a) What component(s) would you insert in this circuit (in the place of Z) to result in the maximum power transfer to the load at a specific frequency 0. Express you result as function of the other component values in the circuit. b) With your added component(s) from part a), what fraction of the total power from the source will be delivered to the load?

Solar Cell

A solar cell, or photovoltaic cell, is a device that converts light into electricity directly through a photovoltaic effect, i.e., a physical and chemical event. It is a type of electromagnetic cell, defined as being used for its electrical properties, current, voltage, or resistance, which vary when exposed to light. Everyday cellular gadgets are usually the building blocks of photovoltaic modules, collectively known as solar panels. Single junction silicon solar cell can generate an open circuit of about 0.5 to 0.6 volts.
