The present invention relates to a hole transport material for a photovoltaic device, and a photovoltaic device comprising the same, wherein the hole transport material is a triphenylamine derivative having a certain substituent introduced thereinto. The triphenylamine derivative having a certain substituent introduced thereinto can be used as material for the hole transport layer in the photovoltaic cell, thereby offering improved power conversion efficiency compared to existing materials. The triphenylamine derivative having a certain substituent introduced thereinto, due to structural characteristics thereof, has high hole mobility, desirable energy levels, thermal stability, and good solubility, and when used as a hole transport material in photovoltaic cells, particularly perovskite solar cell or organic solar cell, shows superior power conversion efficiency and device reliability compared to existing hole transport materials, Spiro-OMeTAD or PEDOT:PSS mixture.
