Low heat, electric energyconversionrate in more than 90%.
发热量低，驱动电能转化率在90%以上。
2
Energyconversionrate was higher because of the feedback of materials in the system.
由于系统内物质的反馈，能量转换率较高。

By using the convex lens to focus the solar energy, the use amount of the crystal silicon batteries is largely reduced and the energyconversionrate is improved.
