The present disclosure relates to porphyrin small molecules substitutes designed and synthesized for bulk heterojunction (BHJ) organic solar cells (OSCs). Provided are synthesized materials with strong and ordered self-assembly property, leading to form bi-continuous, interpenetrating networks which are required for efficient charge separation and transport in organic solar cells. The power conversion efficiency (PCE) of the solar cells devices based on the embodiments of the present disclosure have the highest PCE among the solution-processed BHJ solar cell based on porphyrin small molecules up to date.
