Perovskite Layer

In the search for improvements in perovskite solar cells (PSCs), several different aspects are currently being addressed, including an increase in the stability and a reduction in the hysteresis. Both are mainly achieved by improving the cell structure, employing new materials or novel cell arrangements. We introduce a hysteresis-free low-temperature planar PSC, composed of a poly(3-hexylthiophene) (P3HT)/CuSCN bilayer as a hole transport layer (HTL) and a mixed cation perovskite absorber. Proper adjustment of the precursor concentration and thickness of the HTL led to a homogeneous and dense HTL on the perovskite layer. This strategy not only eliminated the hysteresis of the photocurrent, but also permitted power conversion efficiencies exceeding 15.3%. The P3HT/CuSCN bilayer strategy markedly improved the life span and stability of the non-encapsulated PSCs under atmospheric conditions and accelerated thermal stress. The device retained more than 80% of its initial efficiency after 100 h (60% after 500 h) of continuous thermal stress under ambient conditions. The performance and durability of the PSCs employing a polymer/inorganic bilayer as the HTL are improved mainly due to restraining perovskite ions, metals, and halides migration, emphasizing the pivotal role that can be played by the interface in the perovskite-additive hole transport materials (HTM) stack.

Long Term Stability

Carbon electrode based perovskite solar cells (PSCs) have attracted more attention owing to low product cost, long term stability and simple fabrication technology. Usually carbon electrode based PSCs are fabricated without hole transport layer, which results in slow development in photovoltaic performance and practical application. In this work, we synthesized p-type semiconductor VOx films via low temperature solution process. And the prepared VOx film was introduced into the carbon electrode based PSCs as hole transport layer, which is highly beneficial to further enhance the power conversion efficiencies. Here, we have demonstrated that solution processed VOx film is suitable to be the hole transport layer for PSCs based on low temperature carbon electrode. With the optimized layers of VOx, carbon electrode based PSCs with VOx exhibit enhanced photovoltaic performance compared with hole transport layer free PSCs. In the meanwhile, carbon electrode based PSCs with VOx hole transport layer have long term stability.

We successfully employ low temperature processed conductive polymer PH1000 as an alternative electrode of ITO to fabricate HTL-free PSCs. The best device shows efficiency up to 9.31%, providing a much simpler architecture for the application of PSC.

Formation Reaction

Abstract Nickel oxide (NiOx) hole transport layer was made from nickel oxide powder by a simple process and non-stabilizer or chelating agent. We used ethanol as main solvent and nitric acid less than 2% as co-solvent. The formation reaction mechanism of NiOx thin film was also studied. Perovskite solar cells (PSCs) with the optimum thickness of 70 nm exhibited power conversion efficiency as high as 12.99%, which is superior to those of PSCs with their counterparts. The moisture stability of NiOx based device (non-encapsulated) remained above 70% of their initial output after 700h storage at ambient conditions.
