"Perovskites, a broad class of compounds with a particular kind of crystal structure, have long been seen as a promising alternative or supplement to today's silicon or cadmium telluride solar panels. They could be far more lightweight and inexpensive, and could be coated onto virtually any substrate, including paper or flexible plastic that could be rolled up for easy transport. In their efficiency at converting sunlight to electricity, perovskites are becoming comparable to silicon, whose manufacture still requires long, complex, and energy-intensive processes. One big remaining drawback is longevity: They tend to break down in a matter of months to years, while silicon solar panels can last more than two decades. And their efficiency over large module areas still lags behind silicon. Now, a team of researchers at MIT and several other institutions has revealed ways to optimize efficiency and better control degradation, by engineering the nanoscale structure of perovskite devices." #solarcells #nanoscale #materialscience

Application of Spin Coater in Perovskite Solar Research Perovskite materials boast exceptional attributes, including superior light absorption, impressive charge-carrier mobilities, and extended lifetimes. These qualities pave the way for high device efficiencies and hold the promise of realizing a cost-effective, scalable technology suitable for widespread industry adoption. While challenges in terms of stability and environmental compatibility need to be surmounted, addressing these issues could unlock the transformative potential of perovskite-based technology, paving the way for terawatt-scale solar deployment. Furthermore, the inherent material properties have ignited interest in utilizing hybrid perovskite semiconductors across an expansive spectrum of energy applications, spanning from conventional electronics to cutting-edge optical systems.

Lead-free double perovskites, in particular tin-based perovskites, have emerged to be a promising photo-absorber in solar cells for attaining protruding efficiency and stability. However, the tin-based double perovskite nanocrystals are yet to be investigated in photovoltaics. There are several advantages of nano-crystals over their bulk counterpart, including tunable band gap, higher fluorescence, and higher carrier lifetime, to name a few. In this work, we synthesized vacancy-ordered Cs2SnI6 nanocrystals (NC) and explored their potential in solar cell applications as a photo-absorber for the first time. Due to the 4+ oxidation state of Sn, this perovskite has a high stability against oxidation and hydrolysis during manufacturing and device operation. We also incorporated alkali-metal ion Rb+ in the Cs2SnI6 NCs for a possible enhancement of efficiency and stability in photovoltaic cells. Better carrier extraction was found through this incorporation as the optical band gap of the NCs is narrowed down to 1.39 eV. The Density Functional Theory (DFT) study revealed the change in the electronic band gap and density of states (DOS) of the NCs upon Rb-doping. The photovoltaic device fabricated with the FTO/TiO2/(Cs1−xRbx)2SnI6 NC/CuI/Au architecture has achieved a maximum efficiency of 0.71% with an inspiring short-circuit current (Jsc) of ∼5 mA/cm2. The champion cell has also shown remarkable stability after ∼40 days in an ambient atmosphere. This work, therefore, provides new insights into the alkali-metal ion regulated lead-free fully inorganic perovskite NCs for stable photovoltaic application. https://lnkd.in/gSsprbm4

🌞 Exploring Strategies for Perovskite Solar Module Encapsulation 🌐 Ensuring the long-term stability of perovskite solar cells is the key to unlocking their full potential for practical applications. When it comes to field deployment, the assembly of these cells into modules requires careful consideration, especially in the realm of external encapsulation. The primary goal of encapsulation extends beyond mechanical robustness—it's about shielding the delicate perovskite absorber from environmental stressors like moisture, oxygen, UV light, and temperature fluctuations, all known sources of device degradation. For instance, Ethylene Vinyl Acetate (EVA), a widely adopted encapsulant for silicon solar panels, is incompatible with perovskite-based photovoltaics requiring more research in this direction. 🔍 What to Look for in an Encapsulant Material: - Optical Transparency: To allow efficient sunlight absorption. - Moisture/Oxygen/UV Barrier: Shielding the perovskite layer from harmful elements. - Temperature Resistance: Enduring varying environmental conditions. - Chemical inertness to perovskite 🔗 My personal recommendations to dive deeper into the science: 📖 An Early Systematic Work by the group of Prof. Anita Ho-Baillie.
