					</table><p>An international research team from the <a href="https://tabrizu.ac.ir/en" target="_blank" rel="noopener">University of Tabriz</a> in Iran and <a href="https://w3.bilkent.edu.tr/bilkent/" target="_blank" rel="noopener">Bilkent University</a> in Turkey has developed an inverted all-perovskite bilayer solar cell design with a power conversion efficiency of 24.83% by incorporating innovative materials and optimizing light absorption across a wide spectrum.</p>
<p>The researchers focused on developing bilayer heterojunctions with different perovskite materials to enhance light absorption in various spectrum regions.</p>
<p>Under standard illumination conditions, the team&#8217;s simulations demonstrated positive performance metrics for the inverted all-perovskite bilayer cell.</p>
<p>It achieved a power conversion efficiency of 24.83%, an open-circuit voltage of 0.9 V, and a short-circuit current density of 34.76 mA/cm2.</p>
<p>The top absorber utilizes methylammonium lead iodide, a type of lead-halide perovskite, while the bottom absorber comprises a perovskite material with formamidinium, methylammonium, tin, lead, and iodide.</p>
<p>Together these absorbers were proven to optimize the cell&#8217;s performance.</p>
<p>The study, titled &#8220;Performance analyses of highly efficient inverted all-perovskite bilayer solar cell,&#8221; was published in <em>Scientific Reports</em>.</p>
<p>Using a simulation tool developed by the <a href="https://www.ugent.be/en" target="_blank" rel="noopener">University of Ghent</a>, the team conducted extensive simulations to refine the cell design.</p>
<p>By adjusting the absorber layers&#8217; parameters and the contacts&#8217; work function, they achieved improved performance. Additionally, they discovered that temperature significantly impacts the functionality of the bilayer cell.</p>
<p>The team found that the thickness of the two layers plays a crucial role in the cell&#8217;s performance, emphasizing that the wide bandgap absorber layer should be thinner than the narrow bandgap.</p>
<p>Optimal thicknesses of 100 nm and 600 nm were identified for methylammonium lead iodide and formamidinium, methylammonium, tin, lead, and iodide, respectively.</p>
<p>This breakthrough in solar cell design represents a significant stride toward more efficient and sustainable solar energy and holds potential for large-scale implementation.</p>
<p>Last December, researchers from the Fraunhofer Institute of Solar Energy Systems (ISE) <a href="https://www.mercomindia.com/scientists-claim-efficiency-perovskite-silicon-tandem-cell-large-area" target="_blank" rel="noopener">collaborated</a> with industry partners to achieve an efficiency of 22.55% in a perovskite-silicon tandem solar cell measuring over 100 square centimeters.</p>
<p>Earlier in the month, scientists at the Swiss Laboratories for Material Science &amp; Technology, Empa, claimed to have <a href="https://mercomindia.com/silver-tandem-solar-cells-achieve-record-efficiency/" target="_blank" rel="noopener">developed</a> a low-temperature method using silver to produce a bifacial perovskite-copper indium gallium selenide tandem solar cell.</p>
