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.
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.
Understanding the perovskite active layer is crucial, as its exceptional light absorption and charge transport properties are key to solar cell performance. The perovskite photoactive thin film has the chemical composition ABX₃, in which A is an organic or inorganic cation, B is a metal cation and X is a halide anion (Fig. 1a).
Preparation Methods of the Perovskite Light-Absorbing Layer The synthesis methods of the light-absorbing layer of perovskite solar cells can be roughly divided into three types: the solution method, the vapour-deposition method, and the vapour-assisted solution method.
Perovskite solar cells were prepared with PCBM as the electron transport layer and PEDOT:PSS as the hole transport layer and such cells achieved a PCE of 9.8% . 3.3.
HTMs currently form an integral part of perovskite solar cells. The ideal characteristics of HTMs are a high hole mobility, a good thermal and UV stability, and a well matched HOMO energy to the perovskites. HTMs are the necessary interface modification layer between perovskite and anode in inverted planar PSCs (see Fig. 16).
