Unlocking the Potential of Electronics with Efficient Energy Storage Solutions

Efficient energy capture and storage are essential for powering modern electronics, especially as sustainability takes center stage. Epishine’s organic solar cells provide an innovative way to capture indoor light, reducing or even eliminating the need for traditional batteries. However, to fully realize their potential, these solar cells must be paired with the right energy storage solutions. Selecting the most suitable storage system for each application ensures optimal performance and reliability, even in low-light, or no-light environments.  

The Role of Energy Storage in Electronics  

Energy storage is fundamental to the performance and reliability of electronics, particularly in environments where continuous power supply isn't guaranteed. By capturing indoor light through Epishine’s organic solar cells, it’s possible to reduce or even eliminate dependence on traditional batteries. Pairing these solar cells with effective energy storage solutions is key to maximizing efficiency and maintaining a consistent power supply.  

Choosing the Right Storage  

Epishine’s organic solar cells are highly adaptable, supporting a range of energy storage configurations. Based on specific power requirements and operational environments, the solar cells can be paired with different setups to maximize efficiency and performance: 

• Minimal Storage (Small Capacitor): This cost-effective solution is ideal for applications where power is only needed while light is available, minimizing environmental impact.  

• Medium Storage (Supercapacitor): For use cases requiring intermittent operation in low-light conditions, this configuration offers a battery-free solution that allows for limited performance in the absence of light.  

• Larger Storage (Hybrid Capacitor or Rechargeable Battery): When extended operation during periods of darkness is needed, hybrid capacitors or rechargeable batteries provide reliable performance with long-lasting power.  

• Non-rechargeable Backup Batteries: For applications requiring continuous operation, pairing the solar cell with non-rechargeable backup batteries ensures the system is always powered and that battery lifetime is extended, even in prolonged darkness.   

Each configuration offers unique advantages depending on the operational requirements, whether it’s to maximize efficiency, reduce costs, or extend battery lifetime. Selecting the appropriate storage configuration is crucial for ensuring reliable power, but optimizing how energy is harvested and managed is equally important for achieving maximum efficiency and sustainability.  

Optimizing Energy Harvesting with MPPT  

Epishine’s solar cells have a specific operating point where they deliver maximum power, which shifts depending on light availability. To consistently extract the maximum energy, the solar cells can be combined with a power management integrated circuit (PMIC) that incorporates maximum power point tracking (MPPT) technology. Using PMICs and MPPT, energy conversion efficiency can reach up to 90%, which is especially vital in low-light environments where every bit of energy matters.
