Description

2FIC, namely 2-(5,6-Difluoro-3-oxo-2,3-dihydro-1H-inden-1-ylidene)malononitrile, is electron deficient. It is used as a building block to prepare non-fullerene acceptors (NFAs) such as ITIC-2F, IHIC-2F, IEIC-2F, IXIC-2F for highly efficient organic photovoltaic devices.

Uses

2-(5,6-Difluoro-2,3-dihydro-3-oxo-1H-inden-1-ylidene)propanedinitrile is incorporated into the core of photovoltaic devices to achieve higher current and reduced energy loss for nonfullerene solar cells.

Check Digit Verification of cas no

The CAS Registry Mumber 2083617-82-5 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 2,0,8,3,6,1 and 7 respectively; the second part has 2 digits, 8 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 2083617-82:
(9*2)+(8*0)+(7*8)+(6*3)+(5*6)+(4*1)+(3*7)+(2*8)+(1*2)=165
165 % 10 = 5
So 2083617-82-5 is a valid CAS Registry Number.

Dopant-Free Hole Transport Materials Afford Efficient and Stable Inorganic Perovskite Solar Cells and Modules

The emerging CsPbI3 perovskites are highly efficient and thermally stable materials for wide-band gap perovskite solar cells (PSCs), but the doped hole transport materials (HTMs) accelerate the undesirable phase transition of CsPbI3 in ambient. Herein, a dopant-free D-π-A type HTM named CI-TTIN-2F has been developed which overcomes this problem. The suitable optoelectronic properties and energy-level alignment endow CI-TTIN-2F with excellent charge collection properties. Moreover, CI-TTIN-2F provides multisite defect-healing effects on the defective sites of CsPbI3 surface. Inorganic CsPbI3 PSCs with CI-TTIN-2F HTM feature high efficiencies up to 15.9 %, along with 86 % efficiency retention after 1000 h under ambient conditions. Inorganic perovskite solar modules were also fabricated that exhibiting an efficiency of 11.0 % with a record area of 27 cm2. This work confirms that using efficient dopant-free HTMs is an attractive strategy to stabilize inorganic PSCs for their future scale-up.
