【Product description】
The Heterojunction Technology (HJT) combines high efficiency with a simple design reducing the number of manufacturing steps and achieving an important cost reduction. It combines the advantages of mono crystalline silicon solar cells with the good absorption and the superior passivation characteristics of amorphous silicon leading to a higher efficiency.
The compact and lightweight dual-glass module with 2.0mm tempered glass was successfully developed in 2014. Now, thinner, lighter dual-glass module with 1.6mm tempered glass encapsulated with high efficiency HJT solar cell can be produced. Due to the material and structure characteristics, dual-glass module fundamentally avoid defects such as PID, micro cracks of cells, and snail trail ,which can reduce the investment cost, transport cost and the operation risk of power plants, etc.

Solar panel is a device that directly or indirectly converts Solar radiation energy into electricity through photoelectric effect or photochemical effect by absorbing sunlight. The main material of most Solar panels is "silicon", but due to the large production cost, its widespread use has certain limitations.
