Efficient and stable perovskite-silicon tandem solar cells through contact displacement by MgF <i> <sub>x</sub> </i>
Abstract
<jats:p>The performance of perovskite solar cells with inverted polarity (p-i-n) is still limited by recombination at their electron extraction interface, which also lowers the power conversion efficiency (PCE) of p-i-n perovskite-silicon tandem solar cells. A MgF<jats:italic><jats:sub>x</jats:sub></jats:italic>interlayer with thickness of ~1 nanometer at the perovskite/C<jats:sub>60</jats:sub>interface favorably adjusts the surface energy of the perovskite layer through thermal evaporation, which facilitates efficient electron extraction and displaces C<jats:sub>60</jats:sub>from the perovskite surface to mitigate nonradiative recombination. These effects enable a champion open-circuit voltage of 1.92 volts, an improved fill factor of 80.7%, and an independently certified stabilized PCE of 29.3% for a monolithic perovskite-silicon tandem solar cell ~1 square centimeter in area. The tandem retained ~95% of its initial performance after damp-heat testing (85°C at 85% relative humidity) for >1000 hours.</jats:p>
