A Perspective on the Commercial Viability of Perovskite Solar Cells

Abstract

Perovskite solar cells (PSCs) have received a large amount of research funds due to their potential as a frontrunner in a new generation of solar cells; consequently, the desire to commercialize this technology is mounting. In this roadmap, the knowledge and the technological gaps between laboratory and industry are critically analyzed from the perspective of 5S criteria (Stability, Safety, Sustainability, Scalability, and Storage). To avoid any favoritism in the arguments toward commercializing this technology, herein, the average parameters of PSCs (photoconversion efficiency, durability, cost, manufacturability, and sustainability) estimated from previous studies are analyzed and discussed. Unique opportunities for PSCs in their current stage of achievements are identified, where application‐driven, instead of performance‐driven, developments are shown to favor their commercialization. Efforts required to improve the average performance of PSCs to state‐of‐the‐art levels are also identified and discussed.

Are Perovskite Solar Cell Potential‐Induced Degradation Proof?

“…Perovskite solar cells (PSCs) have shown an extraordinary evolution path in the last few years toward highly efficient thin film photovoltaic (PV) devices [1][2][3] and are already outperforming the well-developed thin-film technologies like CIGS and CdTe. [4,5] Current record efficiency of single-junction perovskite and tandem perovskite/silicon solar cells is above 25% and 29%, respectively.…”

Van der Waals Epitaxial Growth for High Performance Organic‐Free Perovskite Solar Cell: Experimental and Theoretical Insights

“…[1,2] The labscale performance has enabled the PSC technology as the competitors to c-Si solar cells and the way toward their potential commercialization has already been initiated. [3] Despite obvious successes at the lab scale, organic-inorganic hybrid PSCs are still lagging in the aspect of operational stability, which still requires serious research considerations. The fragility of organic moiety within hybrid perovskites such as methylammonium (MA + ) hinders their stability against moisture and heat deteriorating the overall PSC's performance under operational conditions.…”

Optoelectronic Enhancement of Perovskite Solar Cells through the Incorporation of Plasmonic Particles

“…A plethora of routes has been explored to harvest clean energy from this vast reservoir as electric power through various generations of solar cells, such as monocrystalline and polycrystalline silicon solar cells, thin-film solar cells, organic solar cells (such as bulk heterojunction cells fabricated from semiconducting polymers), and dye-sensitized solar cells [ 1 , 2 ]. The latest addition in this series is solar cells that use an organic–inorganic hybrid perovskite as the light absorber, known as perovskite solar cells (PSCs) [ 3 , 4 , 5 , 6 ]. The emergence of PSCs has been phenomenal, starting from the work of Kojima et al with a photoconversion efficiency (PCE) of just ~3.8% [ 7 ] and skyrocketing at an unprecedented pace to ~23% in a decade [ 8 , 9 , 10 , 11 ].…”
