Cells are known as the basic units of life. One thing that plant cells and solar cells have in common is that they are very important to humans and living things on earth. One main difference between plant cells and solar cells is how each harnesses solar energy. Plants harness solar energy to use photosynthesis. Solar cells harness solar energy to convert it to electricity.

One of the main duties of photosynthesis is changing solar energy into chemical energy. Anything that can be digested and all fossil fuels are products of photosynthesis. Many organisms are responsible for carrying out photosynthesis. Organisms carry out this task by converting CO2 or carbon dioxide to organic material. The outcome of this chemical reaction is electrons that are converted to protons and oxygen. The remaining energy from this chemical reaction is then absorbed by carotenoids and chlorophylls.
Solar cells are composed of many semiconducting materials. The most common semiconductor devices are diodes, transistors, and integrated circuits. The main duty of a semiconductor is to control voltages and currents so that everything works properly. Diodes are used to produce DC and AP. Transistors are used to vary the current of a heating element. Integrated circuits are used to demodulate and amplify radio signals. Some advantages of semiconductor devices include small size, consumption of small power, and being very efficient. Another advantage of semiconductor devices is that they can operate under extreme conditions.

Over 95% of solar cells produced are composed of silicon. Silicon is available in large quantities due to the fact that silicon is the second most abundant element on….....
