A solar cell, the fundamental unit in a solar energy system, converts light energy into electric energy by using an unlimited clean energy source: sunlight. Additionally, solar photovoltaics do not cause secondary environmental pollution. A relatively high price in comparison to conventional power generation is the main obstacle to widespread use of solar cells; however, this challenge is currently being overcome by government grant subsidies and market expansion.
The photovoltaic effect is the basic physical process whereby a photovoltaic cell converts sunlight into electricity. Sunlight is composed of photons — packets of solar energy. Each photon contains an amount of energy that corresponds to its wavelength in the solar spectrum. When photons strike a photovoltaic cell, they may be reflected, absorbed, or they may pass right through. The absorbed photons generate electricity.
Dye-sensitized solar cells (DSSCs) consist of a crystallization system, and inorganic and organic thin film systems according to the structure and elements of the solar cells.

- Solar Cells
- Solar (photovoltaic) cells are made from silicon and manufactured to capture sunlight and convert it into electricity.
- Solar Modules
- Modules contain many solar cells connected together and housed in a protective unit to be placed on a roof and survive outdoor elements.
- Solar Panel
- Modules are strung together to create a Solar Energy System, which collects electricity and delivers it to the inverter, and then to your home.
- Solar Array
- Solar array is another name for an integrated, interconnected solar energy system.
- Thin Film Solar Cell
- A thin film solar cell is made by depositing one or more thin layers (thin film) of photovoltaic material onto a substrate.
- Grid Parity
- Grid parity is the point at which electricity can be generated at the same cost (or less) than by burning fossil fuels. If renewable energy is not cheaper in the short or long term, governments and industry will continue to lack the motivation to invest in renewable power. It is likely that the first renewable energy source to achieve grid parity will be solar power.
