It is known for its high electron mobility and good photovoltaic performance, making it a promising candidate for use in the production of efficient and cost-effective solar cells. Additionally, its structure and properties make it a valuable building block for the synthesis of various other organic compounds with potential applications in the field of materials science and electronic devices.

Check Digit Verification of cas no

The CAS Registry Mumber 1190978-94-9 includes 10 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 7 digits, 1,1,9,0,9,7 and 8 respectively; the second part has 2 digits, 9 and 4 respectively.
Calculate Digit Verification of CAS Registry Number 1190978-94:
(9*1)+(8*1)+(7*9)+(6*0)+(5*9)+(4*7)+(3*8)+(2*9)+(1*4)=199
199 % 10 = 9
So 1190978-94-9 is a valid CAS Registry Number.

Green-Solvent-Processable, Dopant-Free Hole-Transporting Materials for Robust and Efficient Perovskite Solar Cells

Lee, Junwoo,Malekshahi Byranvand, Mahdi,Kang, Gyeongho,Son, Sung Y.,Song, Seulki,Kim, Guan-Woo,Park, Taiho

In addition to having proper energy levels and high hole mobility (μh) without the use of dopants, hole-transporting materials (HTMs) used in n-i-p-type perovskite solar cells (PSCs) should be processed using green solvents to enable environmentally friendly device fabrication. Although many HTMs have been assessed, due to the limited solubility of HTMs in green solvents, no green-solvent-processable HTM has been reported to date. Here, we report on a green-solvent-processable HTM, an asymmetric D-A polymer (asy-PBTBDT) that exhibits superior solubility even in the green solvent, 2-methylanisole, which is a known food additive. The new HTM is well matched with perovskites in terms of energy levels and attains a high μh (1.13 × 10-3 cm2/(V s)) even without the use of dopants. Using the HTM, we produced robust PSCs with 18.3% efficiency (91% retention after 30 days without encapsulation under 50%-75% relative humidity) without dopants; with dopants (bis(trifluoromethanesulfonyl) imide and tert-butylpyridine, a 20.0% efficiency was achieved. Therefore, it is a first report for a green-solvent-processable hole-transporting polymer, exhibiting the highest efficiencies reported so far for n-i-p devices with and without the dopants.
