Double-sided solar cells: improving power generation efficiency
 |
A Korean company recently launched their new product, the double-sided solar cell. This new type of solar cell can be used on both sides at the same time, which effectively increases the power generation efficiency. Among the traditional solar cells, the single-crystal silicon cell has the highest light conversion efficiency, which is about 19%. This new type of bifacial solar cell can further increase the light conversion efficiency to 20%-30%. At the same time, the power efficiency of a single-cell battery has also increased from 4 watts to 4.5 watts in conventional batteries to 4.5 watts to 6 watts. With the intensifying contradiction between supply and demand of resources, the further development and utilization of solar energy will surely become the future development trend, and this product has developed a very good development idea.
