Perovskite solar cells have therefore been the fastest-advancing solar technology as of 2016. [1] With the potential of achieving even higher efficiencies and very low production costs, perovskite solar cells have become commercially attractive. Core problems and research subjects include their short- and long-term stability. [7]
Module and cell prices declined even further after 2014 (see price quotes in table). This price trend was seen as evidence supporting Swanson's law (an observation similar to the famous Moore's Law) that states that the per-watt cost of solar cells and panels fall by 20 percent for every doubling of cumulative photovoltaic production. [44]
This means that most solar cell manufacturers are currently equipped to produce this type of solar cells. Consequently, a large body of research is being done all over the world to manufacture silicon wafer-based solar cells at lower cost and to increase the conversion efficiencies without an exorbitant increase in production cost.
Solar-cell efficiency is the portion of energy in the form of sunlight that can be converted via photovoltaics into electricity by the solar cell. The efficiency of the solar cells used in a photovoltaic system , in combination with latitude and climate, determines the annual energy output of the system.
The main obstacle to viable tin perovskite solar cells is the instability of tin's oxidation state Sn 2+, which is easily oxidized to the stabler Sn 4+. [10] In solar cell research, this process is called self-doping, [11] because the Sn 4+ acts as a p-dopant and reduces solar cell efficiency.
The technique offers the potential of low cost because of the low temperature solution methods and the absence of rare elements. Cell durability is currently insufficient for commercial use. [45] However, the solar cells are prone to degradation due to volatility of the organic [CH 3 NH 3] + I − salt.
Solar cell efficiency of perovskite solar cells have increased from 3.8% in 2009 [47] to 25.2% in 2020 in single-junction architectures, [48] and, in silicon-based tandem cells, to 29.1%, [48] exceeding the maximum efficiency achieved in single-junction silicon solar cells.
