Solar Cell Integration

System integration is the key to unlocking true energy autonomy. A light-powered device is not just about the solar cell. It is about the energy storage unit and the power management solution that controls and optimizes energy flow. Together, these components create a smarter and more efficient system.

Our experts, together with our extensive partner network, are here to help you navigate the key considerations involved in building long-lasting, low-power products.

FAQs

What indoor solar cell sizes are available?
Please download our latest product catalogue for detailed information on the available sizes of our indoor solar cells.
Does the solar cell need sunlight?

Epishine’s indoor solar cells do not require sunlight to operate. They are specifically designed for indoor light, such as ambient and artificial light from lamps and other sources. 

What is the lowest measurable lux level they work in?
Epishine's solar cells are designed to function effectively in extremely low light conditions, operating from levels as low as 1 lux. Contact us for more details on your specific application.
How much energy do Epishine's indoor solar cells generate?
It depends on the surrounding conditions but our solar cells generate approximately up to 22µW/cm² at 500 lux. Please download our latest product data sheet for detailed information on the performance of our solar cells.
How do you recycle organic indoor solar cells?​

Epishine's solar cells are RoHS (without exception) and REACH certified.

Check regional rules before disposing of any electronic device or component. If Epishine indoor solar cells are part of a device, follow the regional guidelines for electronic waste disposal.

For further information, refer to our data sheet.

Are the solar cells flexible or bendable?
Yes, Epishine's solar cells are flexible and can withstand up to 1 million bends without impacting performance. However, for specific requirements regarding bend radius, please contact us to discuss your needs in more detail.
