IXOLARTM High Efficiency SolarBIT.
Description
IXOLARTM SolarBITs are IXYS’ product line of SolarBITs made of monocrystalline, high efficiency solar
cells. The IXOLARTM SolarBITs is an ideal for charging various battery powered and handheld consumer
products such as mobile phones, cameras, PDAs, MP3-Players and toys. They are also suitable for
industrial applications such as wireless sensors, portable instrumentation and for charging emergency
backup batteries.
With a cell efficiency of typically 22% measured at a wafer level, SolarBITs give the ability to extend run
time even in "low light" conditions and increase battery life and run time in a small footprint, which can be
easily accommodated in the design of Portable Products. The design allows connecting SolarBITs flexibly in
series and/or parallel to perfectly meet the application’s power requirements.
IXOLARTM products have a very good response over a wide wavelength range and therefore can be used in
both indoor and outdoor applications.
