The word photovoltaic comes from the combination of "photo" (meaning light) and voltaic (meaning electricity) produced by a chemical reaction. The word has been defined as the generation of sun light to produce electricity through semi-conduction with materials.
Electrons are emitted from the sun to the earth. When these electrons are set free by the semi-conduction with a material such as silicon or selenium, the energy (in the electrons) are then released in electric DC form. Photovoltaic (PV) systems produce direct current electricity that is converted via an inverter to produce alternating current or is stored in batteries.
WHY USE LAMINATES ?
- Requires no roof penetrations
- Generates more electricity in real world conditions
- Lightweight, durable, flexible
- Ideal for Building-Integrated (BIPV)
- Easy to install
- Removable
- No polysilicon needed
HOW DOES IT WORK ? : Triple Junction technology
This technology provides unprecedented levels of efficiency and stability for amorphous silicon solar cells Each cell is composed of three semiconductor junctions stacked on top of each other. The bottom cell absorbs the red light, the middle cell the green/yellow light and the top cell absorbs the blue light.
This spectrum splitting capability is one of the keys to higher efficiencies and higher energy output, especially at lower irradiation levels and under diffuse light. PV-products using Triple Junction solar cells, show good stability and excellent outdoor performance
