Engineers at Rice University have solved a long-standing conundrum in making stable, efficient solar panels out of halide perovskites. Chemical and biomolecular engineer Aditya Mohite says the new approach is as efficient as most commercially available solar cells. If the process engineering can bring the roll to roll manufacturing to commercial scale at great economy, solar energy harvesting might get quite a boost. Rice University engineers have shown the manufacture of high-efficiency solar cells with layers of 2D and 3D perovskites may be simplified by solvents that allow solution deposition of one layer without destroying the other. The work solved a long-standing conundrum in making stable, efficient solar panels out of halide perovskites. The effort took finding the right solvent design to apply a 2D top layer of desired composition and thickness without destroying the 3D bottom one (or vice versa). Such a cell would turn more sunlight into […]
