good solubility. PEDOT:PSS also showed appreciable efficiency range of stability
and efficiency.
Inorganic HTMs like CuI and GO greatly improve stability when it acts like a
buffer layer. In addition, NiO doped with other p-type inorganic materials showed
better JV characteristics and suppressed hysteresis. Moreover, the p-type inorganic HTMs are chemically stable, have higher hole mobility, and are cheaper to
manufacture.
Owing to different desirable factors in HTMs, it will be important to explore the
characteristics of potential HTM (Interfacial properties, hole mobility, and charge
carrier recombination) for enhanced device performance in perovskite-based solar
cells. The varied photovoltaic performance among different HTMs is a characteristic
of the interaction of the perovskite and HTM layers. The chemical mechanisms of
such interactions have not been studied in deep at present. For a proper design of new
HTM interfaces, these mechanisms have to be thoroughly investigated. In addition,
the use of inorganic buffer layers to HTM interface needs to be realized for proper
interface contact and stability.
