Several years of rapid development has allowed research groups worldwide to create increasingly efficient perovskite/silicon tandem solar cells. The scientific focus is now shifting towards the better understanding and control of the mechanisms responsible for the impressive performance of these new types of photovoltaics.
Solar cells based on crystalline silicon have been very successful during the worldwide uptake of photovoltaic (PV) technology and currently dominate the PV market. The vast majority of the commercial solar cells used in solar power plants are of the single-junction type and generate electricity using the single p-n junction.
