Colloidal solar battery is actually the principle of the use of light to generate, colloidal solar batteries generally more abundant in the use of more areas, due to photovoltaic cells (photovoltaic cell, attention photocell generally refers to the photosensitive resistor), is a light irradiation Electromotive force of the semiconductor components. In addition to the commonly used single crystal, polycrystalline, Solar Gel Battery amorphous silicon cells, the multi-compound solar cells that do not use a single element of semiconductor materials made of solar cells.
Colloidal solar cells through the series after the package protection can form a large area of solar modules (module), and then with the power controller and other components to form a photovoltaic power generation device. PV power generation is less limited by geographical constraints, because the sun shines on the earth; Solar Gel Battery PV system also has a safe, reliable, no noise, low pollution, no need to consume fuel and erection of transmission lines can be local power supply and construction of short-term advantages. Solar Gel Battery Photovoltaic power generation is based on the principle of photovoltaic effect, when the P-N junction light, the sample of the intrinsic absorption of photons and non-intrinsic absorption will produce photogenerated carriers. But can cause the photovoltaic effect can only be excited by the intrinsic absorption of the minority carriers. Solar Gel Battery Due to the P area generated by the photogenerated holes, N region of the photogenerated electrons are numerous, are barrier barrier can not be knot. Only the photogenerated electrons in the P region and the electron hole pairs (minority) of the photogenerated holes and junctions in the N region can drift over the built-in electric field in the vicinity of the junction electric field. Solar Gel Battery The photo-generated electrons are pulled toward the N-zone, and the photogenerated holes are pulled toward the P-region, where the electron-hole pairs are separated by the built-in electric field. This results in the accumulation of photogenerated electrons near the boundary of the N region and the accumulation of photogenerated holes near the boundary of the P region. They produce a photoelectric field opposite to the built-in electric field of the heat-balanced P-N junction, whose direction is directed from the P region to the N region. This electric field reduces the potential barrier, Solar Gel Battery the reduction of the photogenerated potential is poor, P-positive, N-negative. Thus, the junction current flows from the P region to the N region, and its direction is opposite to the photocurrent. If this time in the P-type layer and N-type layer welding metal wire, connected to the load, the external circuit will have a current through, so the formation of a battery components, put them in series, in parallel, can produce a certain voltage And current, output power.
Colloidal solar cells convert solar energy directly into electrical energy. Whether it is used independently or grid-connected, the PV system consists mainly of colloidal solar panels (components), Solar Gel Battery controllers and inverters, which are mainly composed of electronic components and do not involve mechanical components. Therefore, Equipment is extremely refined, reliable and stable long life, Solar Gel Battery easy installation and maintenance. In theory, photovoltaic power generation technology can be used in any need for power occasions, up to the spacecraft, down to home power, large to megawatt-class power station, small to toys, photovoltaic power everywhere.
Colloidal solar battery superiority is mainly reflected in the low temperature environment, life, discharge depth, discharge efficiency.
1, gel electrolyte, no internal short circuit. Heat capacity, heat dissipation capacity, to avoid the general storage of colloidal solar battery easy to produce thermal runaway phenomenon, Solar Gel Battery because the operation at high temperatures is extremely reliable, colloidal solar batteries will not produce "dry" phenomenon, wide operating temperature range.
2, because the colloidal solar battery is a colloidal solid, Solar Gel Battery so the electrolyte concentration uniform, there is no acid layering phenomenon.
3, low acid concentration, corrosion of the plate is weak, you can use a unique tube plate, so colloidal solar battery life is long.
4, colloidal solar battery plate with antimony-free alloy, colloidal solar battery self-discharge is very low. 20 ° C stored two years later, there are more than 50% of the capacity, that is, within two years without additional electricity.
5, super to withstand deep discharge and high current discharge capacity, with overcharge and over discharge self-protection performance.
6, colloidal solar battery anti-deep discharge capacity, 100% discharge can continue to be connected to the load, in three weeks to restore the original capacity of the charge.
7, the use of new inventions patented PVC partitions to ensure that colloidal solar batteries have better consistency and discharge performance.
8, colloidal solar battery floating charging design life of 6 / 12V design life of 15-17 years; 2V: 18-20 years.
