DC-DC converter technology

This special dc-dc step-up converter allows application of single piece of solar cells rather then the traditional method of connection pieces of solar cells together in series in order to generate sufficient voltage to charge a battery.

This self starting converter can step up voltages of 0.4 V to 4 V or higher with an efficiency of 80% or higher.

A single piece solar cell used in combination with the step up converter gives following advantages when compared with serial connected solar cells;
1. Starting charging already at low lux conditions
2. No partial shading problems
3. Optimum use of available space
4. Less parts reducing change of quality rejects
5. High tech appearance

The company Intivation is using this step-up converter technology and bringing it to the market in mobile phones with integrated solar cells.

Another company that is using this technology is Global Solar Vision who is applying it in the solar cell for LED roadstuds.
