| Abstract |
Organic–inorganic hybrid nature of perovskites have been utilized in organic electronics due to their impressive electrical and optical properties and showed remarkable performance in solar cells. Therefore, it is expected that they can overcome the fundamental limitations of silicon-based solar cells such as weight, opacity, and high manufacturing energy.To improve PCE efficiency in perovskite solar cells (PSCs), the hole transport material (HTM) is one of the important active material because it allows efficient hole extraction at the perovskite-HTM interface. Among the various HTMs, spiro-OMeTAD (2,2',7,7'-tetrakis[N,N-di(4-methoxyphenyl)amino]-9,9'-spirobifluorene) has been commonly used in PSCs as a hole transporting material (HTM). However, one drawback of this material is instability at high temperature. To enhance the thermal stability of spiro-OMeTAD, we have designed and prepared its derivative material spiro-OMeCz, by replacing triphenyl-amine units into carbazole units. Investigation on photophysical-, electrochemical-, and thermal properties of spiro-OMeCz reveals that this material is a promising HTM in PSCs device. |
