Solar LED lighting system technologies and engineering design
The Solar LED lighting is a practical knowledge website that organically combines the design of LED solar lighting system with lighting technologies engineering application
1. Photoelectric characteristics of solar cells When light shines on the solar cell, currents IR and IJ flow through the battery load resistance R and inside the battery respectively, where IJ is the forward current passing through the PN junction. When the light is constant, the photocurrent IP=IR+IJ is also constant. The flow of photocurrent inside and outside the…
When comparing the characteristics of silicon crystal solar cells and LEDs, it can be found that they have many similarities as follows: (1) All are semiconductor devices. Solar cells, like LEDs, are semiconductor devices, which are diodes made of PN structure. It’s just that solar cells convert light into electrical energy, and LEDs convert electrical…
