About Spherical Silicon Solar Cell Modules

About Spherical Silicon Solar Cell Modules

  1. High productivity because silicon is melted and sphericalized.
  2. There is no silicon cutting process, and the light-condensing structure requires less raw materials.
  3. Since crystalline silicon is used, conversion efficiency is high and there is no photodegradation.
  4. Since aluminum is used for the substrate, it will not crack. Also, it can be bent.

Development concept

Compared to conventional crystalline silicon solar cells

  1. Silicon raw material used per 1W: 1/5 or less
  2. Process energy consumption less than 1/2
  3. Achievement of equivalent performance / reliability
  4. Flexible support

High-efficiency elemental technology for concentrating spherical solar cells

  1. High quality silicon sphere
  2. Introduction of textured light confinement structure
  3. Defect inactivation by bulk passivation
  4. Reduction of surface recombination due to surface passivation
  5. Lowering the resistance of the conductive antireflection film
  6. Improvement of light collection rate by optimizing the substrate reflector structure
