Researchers have developed an organic mini solar cell that enables operation at up to 5,000 volts. This opens up completely new areas of application.
Scientists have developed a new organic solar cell that can produce over 5,000 volt voltage. The development could be a sustainable and portable power source for high -voltage devices such as artificial muscles in robots or electrostatic drives.
So far, such applications have either needed heavy batteries or bulky high -voltage converters. The new technology offers a compact and efficient alternative that does not require an external energy supply. The photovoltaic module is based on a special structure in which over 5000 tiny solar cells are switched into series.
This enables tensions that are necessary for high -performance devices. Depending on the materials used, the researchers were able to develop two variants. A version generated 3,970 volts with an efficiency of 19 percent, while a second variant even delivered 5,534 volts, but with a lower efficiency of 6.4 percent.

These values produced the cell under artificial light with a illuminance of 100,000 lux. This roughly corresponds to the intensity of direct sunlight. A special feature of the new technology is its high reliability – even under difficult conditions.
Earlier tests with high -voltage solar cells often failed due to problems such as partial shading or voltage losses through material fatigue. The new solution, on the other hand, shows high stability and could be used in different areas.
Applications in medical technology in which artificial muscles or flexible gripping systems would benefit from an independent power source are conceivable. Electrostatic drives, such as those used in small, light flight robots, could also benefit from the technology.
First practical tests with promising results
The researchers carried out a first practical test with an artificial muscle that received electricity via the solar cell. In the experiment, it was possible to raise a 28 gram object solely by the tension generated. This demonstrates that the system not only works theoretically, but could also enable practical applications in real environments.
In the long term, the researchers plan to further increase efficiency and make the material more flexible in order to make it usable for even more areas of application. If this succeeds, the technology could represent an environmentally friendly alternative to conventional batteries and change many energy -intensive high -voltage applications.
