The details

South Korean researchers have made a significant discovery in the field of solar energy, finding that a combination of fish oil and water-based emulsion can enhance the efficiency of solar panels.

The team found that applying this emulsion as a filter over solar panels could capture ultraviolet (UV) light and convert it into thermal energy.

This breakthrough could potentially increase the conversion efficiency of photovoltaic (PV) modules used in solar panels.

PV Modules and Conversion Efficiency

PV modules traditionally have a conversion efficiency of around 20%, as they are only able to convert near-infrared wavelengths into electricity.

To overcome this limitation, scientists have developed photovoltaic-thermal (PVT) systems.

PVT systems cool down PV modules and increase their efficiency by carrying away heat generated through a heat exchanger using a coolant fluid.

This method, known as de-coupled PVT systems, uses liquid filters to capture wavelengths of sunlight that contribute minimally to electricity generation, including UV, visible light, and near-infrared.

Fish Oil and Water-Based Emulsion Filter

Water has been a common choice for liquid filters in these systems, but it is not effective at absorbing UV rays.

However, the mixture of fish oil and water has proven to be highly efficient in absorbing both infrared and UV light.

This absorption capability significantly increases the energy harvesting potential of de-coupled PVT systems.

In experiments, the fish oil filter demonstrated a remarkable conversion efficiency of 84.4%.

This surpasses systems with traditional heat exchangers (70.9%) and de-coupled PVT systems using a water filter (79.3%).

Additionally, the fish oil filter effectively reduced the temperature of the modules from 46.7°C to 33.1°C.

Potential Applications and Conclusion

The application of this technology is promising as emulsion technology is already well-established in industries such as cosmetics and food.

This makes it easily adaptable to existing solar panel systems.

The fish oil and water-based emulsion filter offers the potential to maximize electricity production during the summer while capturing thermal energy for heating applications during the winter.

This innovative research from South Korean scientists highlights the significant potential of fish oil and water-based emulsion in improving the efficiency and performance of solar panels.
