- V mp is the voltage value at the maximum power point
- I mp is the current density
- V oc is the photoopen voltage
- I sc is the optical short circuit current.
- J sc is the optical short-circuit current density and V oc is the photo-opening voltage.
- the optical bandgap shown in the UV spectrum shows a low bandgap between 1.60 and 1.78, which can be expected to increase the overall photo-opening voltage.
- Example 5 The same result was obtained for Example 5 and Example 10 for the same reason.
- Example 4 Comparing the photoelectric conversion efficiency results of Example 6, Example 8, and Example 9 shows the change according to the bulkiness of the substituent of the acceptor group.
- Examples 6 and 8 showed no significant change in efficiency, but were shown to affect the intermolecular proximity of the polymer due to the proximity of the adjacent naphthalene-dithiophene to the butyloxyloxy group.
- the butyloxyl group is introduced to avoid the proximity of the adjacent naphthalene-dithiophene to the butyloxyloxy group, it can be seen that the efficiency is increased.
- a polymer compound having a high energy conversion efficiency was prepared by maximizing the energy conversion efficiency (%) by optimizing the donor-acceptor combination in the conductive polymer into which the naphthalene-dithiophene compound was introduced.
