2025年2月16日 · 将有机间隔区作为缺陷钝化促进剂与低维相 （LDP） 形成相结合，是提高 3D 甲基铵碘化铅 （MAPI） 在光伏 （PV） 中的效率和稳健性的有效方法。 在这里， 新戈里察大学Saim Emin和慕尼黑大学Tayebeh Ameri等人 采用 3,5-二氟苯-1-碳肟酰亚胺碘化物 （2F）、4-（三氟甲基）苯-1-碳肟酰亚胺碘化物 （3F） 和 2,3,4,5,6-五氟苯-1-碳肟酰亚胺碘化物 （5F） 有机垫片作为 3D/LDP OIHP 太阳能电池中的钝化层。 有机间隔区中的氟原子位置和数量改变了钙钛矿 …

We investigated the formation of photovoltaic (PV) devices using direct n-Si/MAPI (methylammonium lead tri-iodide) two-sided heterojunctions for the first time (as a possible alternative to two-terminal tandem devices) in which charge might be generated and collected from both the Si and MAPI.

2025年2月14日 · Integrating organic spacers, as defect passivation facilitators along with low-dimensional phase (LDP) formation is an effective approach to enhance the efficiency and robustness of 3D methyl ammonium lead iodide (MAPI) in photovoltaics (PV).

2014年8月14日 · In this work we describe how the radiative efficiency of such a well performing “inverted” MAPI solar cell compares to a solution processed OPV cell based on a well-studied bulk heterojunction...

2019年5月7日 · Twenty-micrometer-thick single-crystal methylammonium lead triiodide (MAPbI 3) perovskite (as an absorber layer) grown on a charge-selective contact using a solution space-limited inverse-temperature crystal growth method yields solar cells with power conversion efficiencies reaching 21.09% and fill factors of up to 84.3%.

2021年3月15日 · We demonstrate the growth of methylammonium lead triiodide (MAPI) films via a novel two-step aerosol-assisted chemical vapour deposition (AACVD) method leading to the first ever perovskite-based PV devices using active layers deposited by AACVD. This is a scalable deposition process, requiring less complex equipment than conventional CVD.

2016年2月1日 · The charge carriers generated in the MAPI change the V oc of MAPI/PDPP3T:PCBM parallel-like tandem solar cells from 0.62 V to 0.84 V and demonstrates the V oc-switch effect. The introduction of MAPI layer to the polymer solar cell could reduce the thermalization losses and boost V oc .

In this work, Perovskite Solar Cells (PSCs) were prepared using two different perovskite compositions, first only with methylammonium (MAPI), and then with a mixture of 1:1 methylammonium and formamidinium (MA 0.5 FA 0.5 PI), which is known to be more durable than the first one. The PSCs exhibited reproducible photovoltaic parameters, resulting ...

甲基铵三碘化铅 (MAPI) 一直是钙钛矿太阳能电池最常用的光吸收层，并且还显示出潜在的高理论效率。 然而，迄今为止可实现的效率仍然落后于甲脒基或混合阳离子基对应物。 在这项工作中，双添加剂 2-巯基吡啶 (2-MP) 和 1,2-二氯苯 (DCB) 用于调节晶体取向，产生高晶体质量的 MAPI 薄膜并钝化薄膜的陷阱状态。 令人鼓舞的是，我们能够区分这两种添加剂的功效。 DCB 有效地减小了钙钛矿前驱体中胶体团簇的尺寸，从而帮助湿膜达到临界浓度以启动快速成核。 由此产 …
