Researchers worldwide have been interested in perovskite solar cells (PSCs) due to their exceptional photovoltaic (PV) performance. The PSCs are the next generation of the PV market as they can produce power with performance that is on par with the best silicon solar cells while costing less than silicon solar cells.
A major development in this area is the manufacture of tin–lead (Sn-Pb) perovskite absorbers, which can serve as the bottom cell in tandem solar cells . These materials have band gaps in the range of 1.2–1.3 eV, making them perfect for absorbing the low-energy part of the solar spectrum.
Metal halide perovskite solar cells are emerging as next-generation photovoltaics, offering an alternative to silicon-based cells. This Primer gives an overview of how to fabricate the photoactive layer, electrodes and charge transport layers in perovskite solar cells, including assembly into devices and scale-up for future commercial viability.
Since 2009, a considerable focus has been on the usage of perovskite semiconductor material in contemporary solar systems to tackle these issues associated with the solar cell material, several attempts have been made to obtain more excellent power conversion efficiency (PCE) at the least manufacturing cost [, , , ].
As such, research into perovskite recycling is crucial. One tricky component of perovskites to recycle is lead. Currently, producing 1 GW of energy using the most efficient perovskite solar cell would result in 3.5 tons of lead waste. The main strategy used right now to mitigate lead contamination is in-operation of the solar cell.
All-perovskite tandem solar cells, which combine layers of perovskite materials with variable band gaps, can be produced at low temperatures and are compatible with flexible, lightweight substrates. This makes them particularly appealing for commercial uses.
