Photovoltaic cells connecting perovskites and silicon achieve 25.2% conversion efficiency
Silicon photovoltaic cells account for 90% of the entire market. In terms of cost, stability, and productivity around 20% -22%, they now have no competition. Here is the Analysis of the advantages of perovskite in new solar cell materials .
Research and investments in this sector have made silicon cells reach their maximum theoretical conversion efficiency. Therefore, there are many new concepts of PV cells that will allow reducing energy prices from PV systems and making photovoltaics a widely adopted technology for electricity production.
One of the ideas is the so-called double-connector system. In most cases, it is a layered structure in which a PV cell made in one technology is placed directly on another cell. It maximizes efficiency by increasing the absorption of light in the wider spectrum. Such links have been studied for a long time, but still too expensive to be used commercially. This is …
