Research and development efforts directed at the improvement of photo-conversion efficiency of solar cells are witnessing a significant rise across the world and these activities are leading to some highly improved product varieties. Recently activities in the area have led to the development of solar cells with record-high rate of photo-conversion – 26.3 percent of the sunlight received; the previous record was efficiency of 25.6 percent.
The solar cell has been developed as a result of R&D efforts by researchers in Japan. Being able to devise cells with this remarkable photo-conversion ratio says a lot about the significant development technology has achieved in the field; after all, leaves, which are known to the mankind as nature’s solar cells, have a photosynthesis efficiency of merely between 3-6 percent.
Improvements in Photo-conversion Ratio Necessary to Boost Adoption of Solar Power
The team of researchers from the Kaneka Corporation in Osaka, which is behind the prototype, states that they may have also found a way of creating one more prototype with the maximum level of photo-conversion efficiency considered to be possible for silicon-based cells in theoretical terms – 29.1 percent. To boost the uptake and deployment of solar power projects as an efficient alternative to the highly polluting power-generation technologies powered by coal and other petrochemicals, improvements in photo-conversion efficiency of solar cells are crucial.
The researchers have used industrially compatible processes for the development of large-area silicon-based solar cells. Although the study presents a way to devise silicon solar cells with a significant power conversion ratio, the path from the prototype to commercialization could take some time. Researchers have said that further work is necessary before the individual cells can be brought together to develop commercially available solar panels.
