Through the analysis of current process, the manufacturing cost and the levelized cost of electricity (LCOE) of PSCs is estimated as 0. 57 $ W −1 much higher than that of the silicon solar cells. Perovskite solar cells (PSCs) manufacturing costs are currently roughly competitive with the lower end of. . This rapid development provides a window of opportunity for perovskite technology to be commercialized, promising a cheaper alternative to the most widespread types of photovoltaics,4−6 with lower production costs, material costs, and energy demands during manufacture. Lifecycle assessments of PSCs. . Perovskite solar cells are assembled in highly controlled environments to minimize exposure to moisture and oxygen. When British solar manufacturer Oxford PV shipped the first commercial order of perovskite-silicon solar. . For example, taking into account the preference for very high-purity precursors to limit the potential for defects caused by unwanted elements in the crystal, perovskite precursor inks are quite reasonable in cost. Current production costs are around $0. 16 per watt, with some estimates suggesting it could decrease to. .
