Perovskite Solar Cells
Two-dimensional hybrid perovskites are used as absorbers in solar cells. Our first-generation devices containing (PEA)2(MA)2[Pb3I10] (1; PEA=C6H5(CH2)2NH3 , MA= CH3NH3 ) show an open-circuit voltage of 1.18 V and a power conversion efficiency of 4.73%. The layered structure allows for high-quality films to be deposited through spin coating and high-temperature annealing is not required for devi...
متن کاملMeniscus-assisted solution printing of large-grained perovskite films for high-efficiency solar cells
Control over morphology and crystallinity of metal halide perovskite films is of key importance to enable high-performance optoelectronics. However, this remains particularly challenging for solution-printed devices due to the complex crystallization kinetics of semiconductor materials within dynamic flow of inks. Here we report a simple yet effective meniscus-assisted solution printing (MASP) ...
متن کاملPrinting efficient solar cells
As worldwide demand for fossil fuels depletes reserves, scientists are increasingly focused on generating alternative energy— especially if it can be produced cleanly and inexpensively. Hydroelectric, solar, wind, nuclear, and biomass technologies are replacing coal, oil, and natural gas. Many of these new technologies have similar costs. Yet the availability of materials or existing infrastruc...
متن کاملOrganic Charge Carriers for Perovskite Solar Cells.
The photovoltaic field is currently experiencing the "perovskite revolution". These materials have been known for decades, but only recently have they been applied in solid-state solar cells to obtain outstanding power conversion efficiencies. Given that the variety of perovskites used so far is limited, a lot of attention has been devoted to the development of suitable organic charge-transport...
متن کاملHole-Transport Materials for Perovskite Solar Cells.
The pressure to move towards renewable energy has inspired researchers to look for ideas in photovoltaics that may lead to a major breakthrough. Recently the use of perovskites as a light harvester has lead to stunning progress. The power conversion efficiency of perovskite solar cells is now approaching parity (>22 %) with that of the established technology which took decades to reach this lev...
