a Device geometry of OPV with L-cystine as ETL. The JV curve is displayed. Reproduced with permission from ref. 129. b The device structure of an organic solar cell incorporated with DNA nano layer and the device performance (JV curves) variation with respect to the spin speed of DNA layer deposition. Reproduced with permission from ref. 108. c JV curve comparison of an OPV device incorporated with Polyamino acid and Poly [(9,9-bis(3′-(N,N-dimethylamino)propyl)-2,7-fluorene)-alt-2,7-(9,9–dioctylfluorene)] (PFN) as electron extraction layer. Reproduced with permission from ref. 113. d Carboxymethyl-cellulose (CMC) based OPV device. The effect of different annealing temperature of ITO/ZnO/CMC on the JV curve compared with ITO/ZnO device.
