In our research on semi-transparent organic photovoltaic cells (STOPV), we have been studying performance improvement using average visible transmittance (AVT) and light utilization efficiency (LUE), which is expressed as the product of conversion efficiency and AVT. So far, we have been studying the use of DTB with relatively high AVT. However, the basic conversion efficiency is low, and STOPV has not yet been fabricated. Therefore, we selected a highly efficient p-type semiconducting polymer, PNBTz1, which is expected to have a relatively high AVT, and examined it as a STOPV.
