1.soler cell
#.A solar cell is an electrical device
#. converts the energy of light directly into electricity
#. It is a form of photoelectric cell
#. its electrical characteristics—e.g. current, voltage
#.Most commercially available solar cells are capable of producing electricity for at least twenty years
#.Chinese companies have played an important role in solar panels manufacturing in recent years. China produced solar cells/modules with an output of 13 GW in 2010 which represents about half of the global production and makes China the largest producer in the world
Other name: photovoltaic cell

2.voltaic cell
#.chemical energy changes into electrical energy
#.carring 2 solutions i.e ZnSo4(Zn electrod dipped) and CuSo4(Cu electrode dipped )
#.2 solutions connected by a salt bridge
#.Zn electrode oxidation nd Cu electrode reduction take place
#.electrodes are connected by voltameter in circuit
#.voltameter used to measure volts between 2 electrodes
#current passes Zn to Cu electrode
Other name: galvanic cell Daniel cell nd dry cell

3.fuel cell
#. A fuel cell is a device that converts the chemical energy from a fuel into electricity through a chemical reaction with oxygen or another oxidizing agent
#.Hydrogen is the most common fuel, but hydrocarbons such as natural gas and alcohols like methanol are sometimes used.
#. fuel cells are used for commercial, industrial and residential primary and backup power generation. Fuel cells are very useful as power sources in remote locations, such as spacecraft, remote weather stations, large parks, communications centers, rural locations including research stations, and in certain military applications
