Portable Electronic Devices

Proposal of amorphous silicon solar cells

Allows extended operations for mobile devices by recharging the battery.

Features

Formed in arbitrary shapes
Circular and other shapes are available in addition to square shapes.
Wide range of substrate types available
Glass, film, and stainless steel
Any desired voltage can be designed.
Allows to design any desired voltage on a substrate.

Capable of handling custom sizes while keeping initial costs down.

Solar Example A (E595: Glass type)
External dimensions 57.7mm × 41.3mm
Characteristics 141mW (AM 1.5, 100mW/cm²: under peak weather conditions), 67mW (50K Lx)
Electrical output
(per day)
Calculated based on the daily average sunlight for Tokyo over one year: 141 mW × 3.2 h = 451 mWh/day
Solar Example B (E602: Glass type)
External dimensions 36.1mm × 41.3mm
Characteristics 82mW (AM1.5,100mW/cm²: under peak weather conditions), 39mW (50K Lx)

Applications: To cell phones
