The efficiency of solar cells drops when exposed to light until it has reached the stable value (at around 10-30 % of its initial value) over the course of its service life (25 years).
Deep Discharge/ Deep Cycle Batteries – Definition, Glossary, Details – Solar Mango
Deep discharge/ Deep Cycle Batteries are used as solar batteries or in backup power. They are designed to be discharged down as much as 80% time after time, and have much thicker plates. Deep cycle batteries are capable of surviving…
Czochralski Process – Definition, Glossary, Details – Solar Mango
The Czochralski process is a method of crystal growth used to obtain single crystals of semiconductors and is used mainly in the production of large cylindrical ingots or boules of single crystal silicon. This high grade silicon is used in…
Current at Maximum Power (Imp) – Definition, Glossary, Details – Solar Mango
The current at which maximum power is produced by a solar panel i.e., Pmax = Vpm X Ipm therefore Ipm = Pmax/Vpm. Assumed value = 5.
Crystalline Solar Cells – Definition, Glossary, Details – Solar Mango
The majority of PV cells produced today use crystalline silicon (c-Si) which is a light absorbing semiconductor. Crystalline solar cells are made from silicon wafers, which in turn are made from polysilicon ingots. Crystalline cells could either be monocrystalline (made…
Contact Resistance – Definition, Glossary, Details – Solar Mango
Contact resistance is the resistance between metallic contacts and the semi-conductor. Contact resistance losses occur at the interface between the silicon solar cell and the metal contact.
CIS – Definition, Glossary, Details – Solar Mango
CIS solar cell is made of semiconductor layers of Copper, Indium, Selenium and Gallium and uses the broadest light spectrum of all solar technologies. This enables high yield even under diffused light conditions. Also abbrievated as CIGS solar cells.
Capacity Utilization Factor – Definition, Glossary, Details – Solar Mango
The performance of a PV power plant is often denominated by a metric called the capacity utilisation factor. It is the ratio of the actual output from a solar plant over the year to the maximum possible output from it…
Battery Life – Definition, Glossary, Details – Solar Mango
Battery life of a solar battery is a measure of battery performance and longevity. It is the period during which a cell or battery is capable of operating above a specified capacity or efficiency performance level.
Band Gap – Definition, Glossary, Details – Solar Mango
Band Gap is also known as energy gap. The band gap is the gap in energy between the bound state and the free state, between the valence band and conduction band.The band gap of the semiconductor determines the maximum efficiency…
