Research on polymer solar cells has attracted increasing attention in the past few decades due to the advantages such as low cost of fabrication, ease of processing, mechanical flexibility, etc. In recent years, non-fullerene polymer solar cells are extensively studied, because of the reduced voltage losses, and the tunability of absorption spectra and molecular energy level of non-fullerene acceptors. In this work, polymer solar cells based on conjugated polymer (PBDB-T: poly [(2,6-(4,8-bis (5-(2-ethylhexyl) thiophen-2-yl)-benzo [1,2-b:4,5-b’] dithiophene))-alt-(5,5-(1’,3’-di-2-thienyl-5’,7’-bis (2-ethylhexyl) benzo [1’,2’-c:4’,5’-c’] dithiophene-4,8-dione))]) and non-fullerene electron acceptor (ITIC: 3,9-bis (2-methylene-(3-(1,1-dicyanomethylene)-indanone)) -5,5,11,11-tetrakis (4-hexylphenyl)-dithieno [2,3-d:2’,3’-d’]-s-indaceno [1,2-b:5,6-b’] dithiophene) were prepared by means of spin-coating method, and the influence of the active layer thickness on the device performance was investigated. PBDB-T: ITIC active layers with different thickness were prepared through varying spin coating speed. It was found that the solar cell performance is best when the active layer thickness is 100 nm, corresponding to the spin coating speed of 2000 rpm. Maximum power conversion efficiency of 7.25% with fill factor of 65%, open circuit voltage of 0.85 V and short circuit current density of 13.02 Am/cm2 was obtained.

To reduce energy loss, planar acceptors with high LUMO levels were synthesized for wide-band-gap-polymer solar cells. A PCE of 4.05% was obtained with an active layer thickness of 35 nm and a transmittance of 76.1%.

The thickness dependence of the photovoltaic performance for devices based on the small molecule DR3TSBDT:PC71BM was systematically investigated and the power conversion efficiencies are found to be relatively insensitive to the thickness.
