Low-Temperature Sequential Deposition for Efficient Inverted Perovskite Solar Cells

Low-temperature sequential deposition for efficient inverted perovskite solar cells

Inverted perovskite solar cell has made significant progress in recent years. Although two-step sequential deposition shows the benefits to obtain higher quality large-size perovskite crystals, the high annealing temperature, which is required to achieve phase transition, leads to the desorption of self-assembled molecules at the buried interface and induces redundant lead iodide at the top interface. Here, we propose a low temperature sequentia…

Improving perovskite solar cell efficiency, sustainability with micro-concentrators

Researchers in Italy are tackling two metal halide perovskite solar PV challenges, reduce the use of lead and extend stability of the power conversion efficiency, in a novel combination of micro-concentrators and picosecond laser processing.Researchers from University of Genoa and University of Rome Tor Vergata are taking on two well-known metal halide perovskite (MHP) solar PV challenges, reducing the amount of lead while maintaining a high-lev…
