Progress, challenges, and perspectives on polymer substrates for emerging flexible solar cells: A holistic panoramic review

Abstract: In pursuit of a renewable, inexpensive, sustainable, and compact energy source to replace fossil fuels, solar photovoltaic devices have become an ideal alternative to meet human needs for environmentally friendly, affordable, and portable power sources. It is due to their excellent mechanical robustness and outstanding energy conversion efficiency. Concerning the increasing demand for flexible and wearable electronic devices with standalone power sources, much attention has been paid to photovoltaics' flexibil… Show more

“…Curving device is an ideal strategy to overcome the efficiency limit beyond the planar format due to the introduction of new degrees of freedom, which allows spatial configuration matching and light outcoupling control. Existing curved devices, such as fiber, spherical, and flexible solar cells, have been well-integrated into smart textiles, , self-powered sensors, and greenhouse applications . However, the PCE of curved devices does not exceed that of planar devices even though many efforts in novel materials, device structures, and manufacturing technologies, and some even lag behind significantly. ,,, Although the S–Q limit of planar devices was obtained as early as 1961 and was extended to various real-world solar cells, , the theoretical research on curved devices is almost in the blank stage. Some studies explored the efficiency limit of curved devices in spherical, fiber, and nanowire , devices through kinetic simulation or simplified approximation of solar cell radiation.…”

“…Organic solar cells have gained significant attention in recent years due to their advantages of being lightweight, low-cost, flexible, and compatible with large-area printing fabrication. Small-molecule nonfullerene organic solar cells have emerged as a promising alternative to fullerene-based organic solar cells due to their higher efficiency and better stability. The performance of small-molecule OSCs has been rapidly increasing due to recent advances in designing and synthesizing efficient nonfullerene acceptors and optimizing device structure. Recently, up to 20% conversion efficiency has been achieved due to computational and experimental contributions. , …”

“…As compared to typical planar structure solar cells, fiber shaped solar cells with a unidimensional linear structure offer the advantages of flexibility, lightweight and could be easily woven into wearable electronics [1][2][3]. This advent of fibershaped devices might be provoking a significant transformation in the power reservoir of flexible gadgets [4][5][6]. Hence, diverse range of fiber shaped solar cells including dye-sensitized solar cells [7], organic/polymer solar cells [8] perovskite solar cells [9] and quantum-dot sensitized solar cells [10] have been reported recently [11,12].…”
