“…[133][134][135][136] Nevertheless, there are still limited choices of perovskite materials and their toxicity and instability remain extremely challenging issues to be solved. [137][138][139] In detail, the main factors affecting the instability of perovskite materials include: i) Humidity: as an example, CH 3 NH 3 PbI 3 is hygroscopic and eventually decomposes into CH 3 NH 3 I and PbI 2 when exposed to water. [140] ii) Thermal stress: overcoming the limits of the tetragonal CH 3 NH 3 PbI 3 phase (slightly below ≈50 °C) shortens the durability of the device.…”

conditions. This makes difficult to further reduce the cost of electricity production. [7,8] Furthermore, although solar energy is a renewable source, it does not mean that any kind of photovoltaics (PV) is sustainable. For instance, silicon is an essential material in electronics and solar industries and, up to date, is irreplaceable. Despite its abundancy in Earth's crust, it is for the vast majority (80%) present as ferrosilicon, whose purification is expensive and highly pollutant. The production of 1 ton of silicon requires 6 tons of raw materials, almost 3 tons of Quartz, 1.5 tons of reducing agents, 1.5 tons of wood and 13 000 kWh of energy. [9,10] Therefore, in 2014 the EU commission included silicon metal in the critical raw material (CRM) list. [11] In this context, the third generation PV has reborn, offering cost-effective and efficient CRM-free devices with a lower reliance on the incident angle of light and integration in smart-end applications, like flexible and wearable devices, [12][13][14] fully transparent solar cells and windows, [15,16] and biocompatible devices. [17][18][19] The leading third generation SCs are organic solar cells (OSCs), [20][21][22] perovskite solar cells (PSCs), [23][24][25][26][27] and dye-sensitized solar cells (DSSCs). [28][29][30] Despite their versatile applications and high performances, sustainability still represents a major issue toward becoming an ideal energy technology in the mid-long term future. Among others, fullerene-based materials are toxic, [31] indium tin oxide (ITO) is brittle, chemically unstable, and expensive due to limited indium sources on Earth's crust. [32,33] Cobalt is also listed as CRM, [11] while cadmium, selenium, lead and ruthenium are toxic materials. [34,35] With regard to flexible devices, polyethylene terephthalate (PET) is the standard substrate; though its environmental footprint is critical and its nonbiodegradable properties lead to harmful effects in living organisms. [36] This has fueled a strong cooperation among the fields of engineering, biology, chemistry, and physics to discover new strategies for cost-effectiveness preparation and implementation of bio-derived materials in highly performing PVs.In general, this cooperation constitutes a part of the emerging and multidisciplinary field of biophotonics, [37] which involves biomedical optics, [38] living light, [39][40][41] biomimetic, biomaterials and bioengineered compounds, as well as fabrication/implementation methods applied to optoelectronics [42] and photonics, [43] among others. For instance, artificial lightning and biology have been recently merged with the implementation of cellulose, chitosan, silk, and fluorescent proteins as Accomplishing sustainability in optoelectronics, in general, and photovoltaics (PV), in particular, represents a crucial milestone in green photonics. Third generation PV technologies, such as organic solar cells (OSCs), perovskite solar cells (PSCs), and dye-sensitized solar cells (DSSCs) have reached a mature age and are slowly making thei...

“…The utilization of solar energy has been investigated widely in recent years due to the advantages of renewability and cleanability. , Photocatalysis and photovoltaics are two main routes for the utilization of solar energy. Water splitting to produce H 2 , pollutant degradation, and CO 2 reduction are main important applications of photocatalysis. − Moreover, photovoltaic devices such as dye-sensitized solar cells, quantum dot sensitized solar cells, organic polymer solar cells, and perovskite solar cells (PSCs), which can convert sunlight energy into electricity directly, have attracted increasing attention. − In particular, PSCs have been widely investigated due to their unique advantages of low cost and high efficiency. Hybrid organic–inorganic PSCs have achieved remarkable development since the first report in 2009 .…”

Although lead-based inorganic–organic perovskite solar cells (PSCs) have delivered the highest power conversion efficiency (PCE) to date of 25.2%, the toxic nature of lead and poor stability are the biggest hurdles for the commercialization of PSCs. Lead-free halide double perovskite Cs2AgBiBr6 has received increasing attention as a promising alternative for toxic and unstable organic–inorganic perovskites in PSCs due to its nontoxicity, high structural stability, and unique photoelectric properties. However, the PCEs of Cs2AgBiBr6-based PSCs are strongly restricted by the inherent and extrinsic defects in Cs2AgBiBr6 films. Thus, an in-time review to summarize the research progress of Cs2AgBiBr6-based PSCs to provide strategies for the enhancement of PCEs is critical. In this review, the recent advances in Cs2AgBiBr6 as a light absorber in PSCs are summarized and discussed with an emphasis on the structural, photoelectric, and physical properties of Cs2AgBiBr6. The synthesis and fabrication methods of Cs2AgBiBr6 crystals and films are also reviewed. Importantly, strategies for improving the photovoltaic performance of Cs2AgBiBr6-based PSCs are presented, including band gap engineering, film quality optimization, and interface engineering. Finally, current challenges and perspectives are presented. This review aims to provide useful guidelines for future research in this emerging field.

“…Utilization of the nanomaterials is a substantial method in various fields of science such as catalysts, − drug delivery, − absorbents, − wound healing, , supercapacitors, − and solar cells ,,− to improve the efficiency of the systems. In the same line, nanoscience has generated proof-of-principle photovoltaic cells consisting of perfect crystals, compared to large perfect silicon crystals with high-cost production procedures. ,− By looking at the recent reports, it is determined that incorporation of the metal-containing structures (especially lead) into the perovskites is being substituted by the use of different nanospecies. ,, Recently, there have been several achievements over halide organic–inorganic nanostructures, in which the photoelectric and photovoltaic properties of the perovskites were highly improved, while there is no vestige of the lead (Pb) element at their structures . The toxicity of lead metal and the instability of lead halide perovskite nanocrystals prevents their engineering; hence, concentrating on the preparation of lead-free perovskite single crystals rendering enhanced luminescent features seems urgent.…”

Herein, a concise survey on the latest enhancements of the recently discovered metal-free halide perovskites (MFHPs) as the last member of the ABX3 perovskite systems is portrayed with regard to its preferential characteristics, functions, and diverse structure. Even with features such as electronic band structures similar to physical characteristics such as liquids applied in optoelectronic systems, the heyday of metal-halide perovskites did not last long, because of the emergence of MFHPs. Indeed, the toxic nature of Pb-containing halide perovskites obstructs scaling up in practice while tending to eco-benign materials utilized in the adjustable design and functional probing has come into view as a significant hotspot in photovoltaic research. The MFHPs emerge with unprecedented properties, including light weight, excellent optoelectronic function, variable chemical structures, adjustability, mechanical adaptability, and environmentally benign procedures. These organic semiconductors with good efficiency and long-term stability are used in light-harvesting devices. Here, in the enterprise to upgrade the latest state of the art, we mean to have a quick browse on the various crystalline structure, synthesis approaches, and different properties of metal-free organic halide materials such as ferroelectric, dielectric, piezoelectric, charge-transport, electrocaloric refrigeration and mechanical properties. Future perspectives on this late-rising category also are submitted.
