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.
本公开涉及为体异质结(BHJ)有机太阳能电池(OSCs)设计和合成的卟啉小分子替代物。提供了具有强大和有序自组装性质的合成材料,导致形成双连续、相互渗透的网络,这对于有机太阳能电池中的高效电荷分离和传输是必要的。基于本公开实施例的太阳能电池器件的光电转换效率(PCE)在迄今基于卟啉小分子的溶液处理BHJ太阳能电池中具有最高的PCE。
