| Features of Kyocera Solar Modules Equipped on Prius |
| ■ High quality derived from the fully integrated production process |
|
In 1982, Kyocera successfully began mass production of multicrystalline silicon solar cells using the casting method, which has now become the mainstream method used in solar power generating systems today. Since then, Kyocera has carried out all production processes in-house, from procurement of raw materials to silicon casting, cutting, wafer substrate production, cell production, and solar module assembly. The integrated production process enables Kyocera to make improvements in each step of the production process including the fusing and casting of raw materials, thus making it possible to enhance overall quality by implementing quality improvement, performance enhancement and cost reduction.

| ■ Kyocera solar cells utilize unique technology |
|
A high level of aesthetic quality was also required of the design of the solar modules to be mounted on the roof of the new Prius model. Since 2002, Kyocera has offered high-performance solar cells to the global market that utilize a unique Reactive Ion Etching (RIE) technology.
RIE is a technology utilized to create microscopic ridges on the surface of the cell using plasma and reactive gases. The subtle ridges allow the solar cells to better absorb the sunlight reflected on the surface, therefore enhancing output and conversion efficiency. At the same time, a uniform dark navy blue color has been realized. The product responds to customer needs not only in terms of performance but also with its stylish appearance.
