Which solar cell fabricated by CVD method has the highest efficiency?

Based on the J-V measurements, CH 3 NH 3 PbI 3-x Cl x perovskite solar cell fabricated by CVD method showed the highest efficiency of ~11.1% compared with CH 3 NH 3 PbI 3 perovskite solar cell with a PCE of 9.2%. Note that these J-V curves were obtained by the reverse scan and the forward scan results are shown in Fig. S9.

Can vapor deposition produce planar heterojunction perovskite solar cells?

We report a facile one-step method to fabricate planar heterojunction perovskite solar cells by chemical vapor deposition (CVD), with a solar power conversion efficiency of up to 11.1%.

Can vapor transport be used to fabricate perovskite solar cells?

In this work, we explore the simplified vapor transport approach for perovskite solar cell fabrication, developing a simple one-step chemical vapor deposition (CVD) method to fabricate both triiodide and mixed halide perovskite solar cells with a PCE exceeding 11%.

Can a one-step CVD process be used to fabricate perovskite materials?

In summary, we have suggested the use of a one-step CVD process to fabricate perovskite materials and heterojunction planar solar cell devices. The perovskite films were deposited onto c-TiO 2 -coated FTO glass via in situ reaction of PbI 2 or PbCl 2 and CH 3 NH 3 I vapors.

How to prepare a solar cell from a gas phase?

Up to now, two general methods, namely, deposition from solution and evaporation from the gas phase have been explored to prepare mesostructured 16, 17, 18, 19 and planar heterojunction 20, 21 perovskite solar cells, respectively.

Why do solar cells have a high performance photovoltaic device?

More importantly, these materials hold promise for high performance photovoltaic devices, i.e. solar cells, due to higher charge carrier mobilities and longer diffusion lengths than many organic semiconductors 5, 6. In addition, their band-gap can be conveniently and widely tuned via doping process 7, 8, 9, 10, 11.
