In perovskite photovoltaics (PSCs), the role of hole transporting material (HTM) is highly important as it significantly influents to global device’s performance and stability. Hole transporter ensures extraction at perovskite/HTM interface transport towards cathode. Thus, accurate molecular design affording efficient cost-effective HTM major interest. Small molecules having glass forming property an attractive class can form morphologically stable thin film. Herein, a carbazole bearing polymerizable function was designed synthetized. Its characteristics are suitable for application in PSCs. The preliminary photovoltaic lead device efficiency 14–15% depending on chemical composition employed. These promising results open way new alternative polymeric HTMs solution processed hybrid solar cells.
