Description
Rukon Uddin and Hidir Duzkaya design a cheaper, lead-free perovskite solar cell in computer simulations, in a 2026 paper. Standard designs need a costly hole transport layer and pricey back contacts. Their cell drops that layer entirely. A tin-based absorber avoids toxic lead. A tungsten compound layer moves electrons instead. Nickel, a cheap metal, forms the back contact.
A standard simulator tuned each part of the stack. Layer thickness, doping, and defect levels were optimized in turn. Resistance settings were also refined. The final design reached about twenty-six percent efficiency. Voltage, current, and fill factor all landed at strong values. Nickel costs a tiny fraction of the gold it replaces. The authors offer the design as a viable budget route. Real fabrication tests are the obvious next step.
