High-speed printing of a bulk-heterojunction architecture in organic solar cells films

Abstract

To facilitate the potential applications of organic solar cells (OSCs), highly cost-effective processing fabrication of solar cells and modules is an important prerequisite. However, process development has received little attention...

Robust and Sustainable Indium Anode Leading to Efficient and Stable Organic Solar Cells

“…These results illustrated that the stable InCl 3 -ITO anodes facilitated the access of high-performance and stable, yet low-cost OSCs (Figure 4e). In addition, beyond the small-area OSCs, the feasibility to access large area modules [54][55][56] was demonstrated. Through an aqueous soaking process, we have succeeded in preparing large-area InCl 3 -ITO substrates with excellent uniformity and optoelectronic properties, which impressively led to highperformance organic solar modules (Figure 5; Supporting Information).…”

Cost-Effective Cathode Interlayer Material for Scalable Organic Photovoltaic Cells

“…Additionally, the rate at which CILs are printed in the R2R process remains a significant concern. The linear coating speeds achievable in other processes, such as electrode production and active layer printing, have exceeded 20 m min –1 . − As suggested by the characteristic lines for evaporation and Landau-Levich regimes, higher coating speeds lead to thicker films. − Constrained by the absorption of existing CIL materials in the visible light range or their low electrical conductivity, CILs are meticulously fabricated within a specific range of film thickness . The coating speed range usually remains below 3 m min –1 .…”

A facile synthetic approach based on thieno[3,4-c]pyrrole-4,6-dione to construct polymer donors for highly efficient organic solar cells

“…Moreover, OSCs have progressed rapidly with impressive operational stability (80% of its initial PCE) for over 10 000 hours under continuous light irradiation through various modulation strategies. [12][13][14] With significant breakthroughs in device efficiency and stability (or lifetime) in recent years, the cost factor, which is one of the golden triangle elements, still requires more effort to realize the commercial application of OSCs in domains, 15,16 such as the design and synthesis of low-cost photoactive materials, highthroughput fabrication of solar cells or modules, 17,18 and recycling of functional materials, 19 which can be useful to reduce the levelized cost of electricity. [20][21][22] Typically, the active layer material cost is an important part of the cost of solar modules in an industrial scenario.…”
