  In this prospective talk,work,we disclose the synthesis and characterization of a series of polymerpolymer bulk hetero-junction(BHJ)blends,which incorporate benzodithiophene(BDT)-based donoracceptor(D-A)copolymers as donor,naphthalene diimide(NDI)-based D-A copolymers as acceptor.By introducing different numbers of alkyl aromatic side chains to the donor polymers,together with crstallinity modification on acceptor polymers,the performance of all-polymer solar cells was greatly improved and optimized power conversion efficiency(PCE)over 6.0%was obtained with a high Voc of 1.0 V.
