During the last decade, solar PV has seen a substantial improvement in efficiency: from 16% in 2010 to 22% in 2021. The efficiency value of silicon solar cell is moving towards the maximum achievable limit of 29.2% Integration of tiny, highly efficient, multi-junction cells on top of standard silicon panels.
In the February 25, 2021 issue of Nature, Seo et al. reported a perovskite solar cell with a certified conversion efficiency of 25.2%. We discuss how improving the carrier management with electron transfer and the perovskite layer are key for achieving high-efficiency perovskite solar cells.
This great development in the efficiency is not matched if the cost of the device is considered. The highly efficient PVs (mainly multi-junction solar cells) are prohibitively expensive , . On the other hand, the efficiency of the most dominant technology in the market (i.e. Si) is 25% in the lab and less than 20% commercially.
Ross and Hsiao reported that the efficiency cannot exceed 29% based on an ideal theoretical analysis, where entropy and unavoidable irreversibility place a limit on the efficiency of photochemical solar energy conversion.
Some thorough theoretical analyses with more restricted practical assumptions indicated that the limit is not far above the obtained efficiency . Currently, we are in the midst of the third generation solar cell stage.
Silicon solar cells have been widely used in the photovoltaic industry for many years due to their efficiency, reliability, and affordability. However, these cells are approaching their maximum theoretical efficiency limit of 29%, set by the properties of the silicon material.
