Perovskite Quantum Dot Solar Cells with 15.6% Efficiency and …
We developed lead halide perovskite quantum dot (QD) solar cells with a combinational absorbing layer based on stacked α-CsPbI3 and FAPbI3. α-CsPbI3 QDs, with a relatively wide bandgap of 1.75 eV, are not ideal for single-junction solar cells. We show that the absorption can be broadened by the introduction of another QD layer with a …
Perovskite Quantum Dots for Photovoltaic Applications
The first Pe-QD solar cell was fabricated by Swarnker and his coworkers [], it was made of the cubic CsPbI 3 (α-CsPbI 3) without volatile organic group [] showing 10.77% efficiency and improved stability pared with the thermodynamically stable but optically undesirable orthorhombic CsPbI 3 (δ-CsPbI 3) of 2.82 eV bandgap, the 1.73 eV …
Organic—inorganic hybrid solar cells: A comparative review
Section snippets Device structure and general operating principles. The device fabrication and operation of hybrid solar cells is very similar to that of organic solar cells, the only difference being that the organic electron accepting material of PCBM (or other fullerene derivatives) is replaced by an inorganic nanoparticle.
