Photovoltaic, What and How

Who are know about photovoltaic? I believe majority of you knows that. The limitation of un-renewable energy (such as crude oil, natural gasses etc) source is problem for people over the world. Now, we are trying to use other energy source which can be renewed easily and in short time. Many energy source are provided in our surrounding, and the engineer and scientist considered all of those. Wind, water, solar etc are the renewable energy source met in our daily life. Thus, this photovoltaic use the solar light as main of power generator for producing electricity energy.

Easily, photovoltaic is made by semiconductor material consisted of non-stable electron structure (III-A and V-A group materials). Because of that structure, the electron can be easily moved because of solar light collision. That moves produce electricity power.

The poster below is made by me when I was student in bachelor degree. This poster is published in my laboratory information board. This gives information about basic of photovoltaic system and its application. This poster was made by software Corel Draw X13. If you need the original sources in extension .cdr, you can emailed me.
