Perovskites are basically a class of materials that have a similar structure and possess various characteristics such as magnetoresistance and superconductivity, owing to which, they are being increasingly used in solar cells for generating solar power. Furthermore, the perovskites-based solar cells offer greater convenience, in fabrication, and are available at much lower costs than the traditionally used solar cells. In addition to this, these solar cells provide excellent power conversion rates, which in turn, leads to higher efficiency in power generation. 

Besides the above-mentioned factors, the other reasons behind the soaring sales of perovskite solar cells (PSCs) are the surging awareness amongst the people about the various advantages offered by these cells over the conventionally used silicon photovoltaic (PV) systems and the rising number of research and development (R&D) activities being performed on PSCs. Moreover, the increasing popularity of solar energy is boosting the demand for affordable and efficient solar cells, which is in turn, propelling the growth of the global perovskite solar cell (PSC) market. 

Apart from solar panels, perovskite solar cells are majorly used in the applications pertaining to utilities, electronics, and smart glass. Out of these, the smart glass applications are expected to generate significant demand for perovskite solar cells in the coming years. This is predominantly attributed to the soaring utilization of the PSCs in glass windows, in order to generate electricity from the absorbed sunlight. According to Lance Wheeler, a solar energy expert working at the National Renewable Energy Laboratory in Colorado, the U.S., the glass windows of office and residential buildings have tremendous potential to create electricity.

In addition to being highly efficient, the other beneficial trait of the PSCs is their ability to be tuned in order to absorb light at specific frequencies. This tuning is done by altering the chemical recipe of the materials. This idea was put to practical use, when a team supervised by Richard Lunt, who is a chemical engineer in the Michigan State University, tuned the PSCs for developing an ultraviolet (UV)-absorbing perovskite-based solar window possessing a light-to-energy conversion efficiency of 0.5%.

Out of the Latin America (LATAM), Asia-Pacific (APAC), North America, Middle East and Africa (MEA), and Europe regions, the perovskite solar cell market is predicted to exhibit substantial growth in North America in the forthcoming years. The main factors responsible for the ballooning demand for perovskite solar cells in the North American countries are the  soaring utilization of solar energy and the increasing number of research and development activities being conducted, especially in the U.S., in order to develop better and advanced PSCs. 

Therefore, it can be said with certainty that the sales of perovskite solar cells will skyrocket all over the world in the upcoming years, mainly because of the rising adoption of solar energy technologies and the increasing usage of PSCs for solar power generation in many countries around the world.
