Simply put- the cost. Before I go in to detail about usage and implementation of solar cells, let me explain just how they work. Solar cells, also known as photovoltaic cells (Photo= light Voltaic=electricity) capture photons, convert them into electrons, and use these electrons to transfer energy to whatever you want to power. To do this, solar cells are made with a material called a semiconductor, which, for solar cells is almost always silicon. When light hits this material, it causes electrons to break loose and flow throughout the material.
However, the x-ray technique based on synchrotron radiation becomes a strong development in recent years. There are two reasons which could explained that: on one side the availability of this brilliant x-ray source based on synchrotron radiation as it fostered the application of x-ray optics; on other side, the” nanoworld” is developing so fast, therefore, the researchers were encouraged to find new and power full method to characterize nanostructures . 2. Background about Solar cell: Actually, the biggest Earth’s solar resource is the sun. However, the Earth intercepts about 1400 W/m2 at the top of the atmosphere (on any surface pointing directly at the sun) .

To begin, we will take a look at solar energy. Solar energy is exactly what is it, energy that comes from the sun. Solar energy is a process in which solar rays or the heat that the sun gives off is collected by solar panels made up off cells called photovoltaic (Toothman). These cells are made of silicon in its crystalline form and other semi conductive materials combined with it. When the sun light hits the silicon, the heat causes the electrons in the material to start moving freely.

Solar panels work with what could also be called the photovoltaic process. Where radiation energy is absorbed and creates electricity (voltaic). “Radiation energy is absorbed by semiconductor cells – normally silicon – and transformed from photo energy (light) into voltaic (electrical current). When the sun’s radiation hits a silicon atom, a photon of light energy is absorbed, ‘knocking off’ an electron. These released electrons create an electric current.The electric current then goes to an inverter, which converts the current from DC (direct current) to AC (alternating current).
