How efficient is a perovskite solar cell?

The perovskite solar cell efficiency is an excelling aspect where this technology stands out. Researchers have achieved up to date a recorded efficiency of 29.15%, almost 30%, which is 3.75% more than the highest efficiency recorded for crystalline silicon Al-BSF technology.

What is a n-i-p perovskite solar cell?

An n-i-p perovskite solar cell features a Gold (Au) anode and a Fluorine Doped Tin Oxide (FTO) transparent layer, while p-i-n perovskite solar cells can feature Aluminum (Al) cathodes and Indium Tin Oxide (ITO) anodes.

How do perovskite solar cells differ from Al-BSF c-Si solar cells?

The structure of perovskite solar cells differs slightly from the classical structure of Al-BSF c-Si solar cells. Perovskite solar cells can be manufactured using conventional n-i-p or p-i-n architecture, sandwiching the perovskite absorber layer between a Hole Transporting Layer (HTL) and an Electron Transporting Layer (ETL).

Are perovskite solar cells a viable alternative to c-Si solar panels?

Perovskite solar cells are the main option competing to replace c-Si solar cells as the most efficient and cheap material for solar panels in the future. Perovskites have the potential of producing thinner and lighter solar panels, operating at room temperature.

Why should a perovskite top cell be transparent?

As a primary purpose, the perovskite top cell should be able to convert UV/visible light as efficiently as possible, and, at the same time, it should be highly transparent to those lower-energy photons in the NIR spectral range that will be absorbed by the bottom cell.
