In addition, the peak output power of this high-performance solar cell also reached 4.73 watts. In general, silicon-based solar cells using screen printing technology have a conversion efficiency of 17% to 18.5%.
PERC is "emitter and backside passivation battery." The backside of these solar cells is covered with a dielectric and metal layer with local contact points. This new structure optimizes the optical and electrical properties of solar cells. The projected light can be reflected on the back of the cell so that the emitter can convert more light into electricity. The front face of this high-performance battery has also been optimized.
The unique battery design concept has improved the performance of the battery and can be used even under weak light conditions. Due to the high open circuit voltage, the temperature coefficient is significantly better than other standard solar cells. Therefore, solar modules using these solar cells have a corresponding increase in output power even under weak light, and can increase ambient temperature and increase the annual output of electrical energy.
The exit signs category features lighted LED exit signs to comply with building fire codes and insurance standards. These energy-saving, illuminated, long-life LED exit signs to use less than 5 watts of power, lowering your energy consumption and saving you money every month. An exit sign is a device in a public facility (such as a building, aircraft, or boat) denoting the location of the closest emergency exit in case of fire or another emergency. Most relevant codes (fire, building, health, or safety) require exit signs to be permanently lit.
We offer a wide range of designs and features for LED exit signs including glass exit sign, aluminum and acrylic exit sign, ABS and acrylic exit sign, and ABS exit sign.
