Here’s the first such tandem perovskite cell! Founded in China and amazed by its stability

perovskite photovoltaic cells It is gaining popularity in the scientific world. Especially since their energy conversion efficiency has increased significantly from less than 4%. To more than 25 percent, of course, the efforts of various groups of researchers continue, but in the near future, perovskite photovoltaic cells have replaced those currently operating on a silicon-based basis.

Researchers from Nanjing University in China shared the pages of a scientific journal i lite Information about the newly built All-perovskite monolithic bi-phase solar cell. It is the first invention of this kind in the world.

The first biphasic tandem perovskite cell was manufactured in China

Tandem links differ from classical links in that they have two pipettes arranged in parallel. These types of cells are very promising for today’s technology, since they are cheaper to produce than their silicon counterparts, still have a high specific strength and are also flexible.

According to Chinese researchers, In their invention, they replaced the back metal electrodes with conductive oxide electrodes. They used the “bandgap” technique.

According to scientists’ calculations, it turns out that Combined biphasic perovskite cells They provide greater stability and a significant increase in energy yield compared to single-phase cells. This is in addition to the different weather conditions, climatic conditions, and the albedo variable (light reflection).

The Chinese invention brings an entirely new structure to photovoltaic cells that can be used for commercial purposes.
