Abstract

Perovskite solar cell (PSC) technology has received considerable attention due to the rapid escalation of their solar-to-electrical energy conversion, which has recently surpassed 25% for lab-sized solar cells. Other benefits...

Recent developments in perovskite-based precursor inks for scalable architectures of perovskite solar cell technology

“…In contrast, other potential scalable methods such as drop-on-demand inkjet printing 136,208–210 have yet to be proven as a reliable process step for large perovskite layer deposition in order to overcome advanced key challenges related to creating flexibility in pattern designs of any choice through high precision and resolution. 15,17,211 These challenges call for the development of room temperature-based chemically stable precursor inks that can pass through without clotting the micro-nozzles of the inkjet cartridges, in order to deliver precise microlitre-sized drop volumes over the desired surfaces. 15,17…”

“…11 Its key features include solution processing, which offers the possibility of rapid production of perovskite solar modules (PSMs), efficient solar-to-electrical energy conversions under various light intensity conditions, 12,13 and the well-established long term operational stability under various environmental conditions. 12,14–18 Thus, PSC technology has become a unique candidate among other emerging and next-generation-based photovoltaic (PV) technologies 19–22 in the emerging area of building-integrated photovoltaics (BIPV) 23 and for the next generation of maintenance-free IoT devices. 24–26…”

“…27,28 These have utilized various unique and advanced perovskite precursor inks for achieving efficient large-area PSCs and modules 29,30 while demonstrating striking stability when tested under both simulated and natural environmental conditions. 16–18 This report summarizes the trends that have emerged during the research and development of producing scalable perovskite precursor ink formulations, and it also discusses their contribution toward efficient, scalable, and durable PSC technology.…”

Ink Engineering in Blade‐Coating Large‐Area Perovskite Solar Cells

“…The perovskite precursor ink plays an important role in determining the final device performance. [ 40 ] Generally, the perovskite ink engineering for the blade‐coating process involves perovskite composition management, solvent selection, and additive modification. All these factors play critical roles in determining the perovskite crystallinity, defects, and interface connections with carrier transporting layers.…”
