SLMD960H09L

Solar cells are solar energy devices, which use photovoltaic effect to convert solar energy into electrical energy, and widely used in solar photovoltaic systems such as solar street lights, solar toys, solar gardens, solar water pumps and solar energy power generation. The SLMD960H09L solar cell is a new type of solar cell with a conversion efficiency of up to 19.9% and a built-in bypass diode for bypass current.

SLMD960H09L Application Field

The SLMD960H09L solar cell is widely used in outdoor solar products such as solar lights, solar chargers, outdoor flashlights, solar house power systems, solar mobile power systems, and other applications requiring high-efficiency and low-light solar energy applications. . It is also widely used in other solar power generation systems such as solar farms and solar street lights.

SLMD960H09L Working Principle

SLMD960H09L solar cells make use of the photovoltaic effect to convert solar radiation energy into electrical energy. When the incident solar light is absorbed by the semiconductor material, the energy of the light is converted into heat energy, which is converted into electricity by using the photovoltaic effect.

The SLMD960H09L solar cell is a high-efficiency solar cell composed of two layers of semi-insulating silicon. Its structure is divided into three parts: the P-type region on the top layer is the side where the incident light is absorbed; the N-type layer at the bottom is where electrons flowing from the P-type layer are diffused and stored, and the contact region at the bottom where the metal is in contact with the outside. The incident light of the solar cell is absorbed by the P-type region, which causes the generation of electron-hole pairs, and electrons migrate to the N-type layer of the solar cell due to the built-in electric field, while holes migrate to the metal contact of the P layer due to the built-in electric field. Through the contact between the metal and the P-type region, the holes escape from the P-type region and the circuit is completed, thus generating a current.

The SLMD960H09L solar cell has a built-in bypass diode, which is used to prevent solar cells from being damaged by reverse current. When the blocking voltage of the solar cell is higher than the predetermined value, the bypass diode is turned on and the current flows from the bypass diode instead of from the solar cell.

In summary, the SLMD960H09L is a high-efficiency solar cell used in solar photovoltaic systems. It makes use of the photovoltaic effect to convert solar energy into electrical energy, and it has a built-in bypass diode to protect the solar cell from reverse current. It is widely used in outdoor solar products such as solar lights, solar chargers, outdoor flashlights, solar house power systems and solar mobile power systems.
