Solar World
Application of organic electronics for low-cost photovoltaic shows an emerging field. Figure in organic solar cells is the use of optical microscope pictures and cross-Gaussian filter polarizers and shoot Norma made.
The two circle the moon like a metal cathode. These films annealed devices can often improve the power conversion efficiency. This photo is in the annealing temperature is close to the melting point of the battery components to shoot the scene, thus creating a map of the special stripes.
What is the hydrogen fuel cell vehicles
Hydrogen fuel cell vehicles is the use of hydrogen in fuel cells react with oxygen to produce a drive motor power, to promote the car forward. Therefore, it is the kind of electric vehicles, rather than traditional internal combustion engine vehicle.
The world's most compact, powerful is the new General Motors fuel cell research. It is the power density of 1.75 kilowatts per liter, and create a new world record. The volume of the battery pack 819 x 140 x 508 mm (58 liters), weight 82 kg, continuous power output of 102 kW. The battery pack can also cope with higher peak demand in the short period of time up to 129 kilowatts of electricity. Internal combustion engine of this size even smaller than the average.
The battery on the battery pack in parallel What are the requirements?
Parallel batteries to equal the force of the battery, otherwise the battery will force a large force small battery discharge, the formation of circulation within the battery pack. In addition, the internal resistance of each battery should be the same, otherwise the internal resistance of the battery discharge current is too large. Condition should not be used in parallel with different batteries.
