Study of thin film coating technique parameters for low cost organic solar cells fabrication

In this work, fabrication of P3HT: PCBM polymer solar cell from spin coating in glove box environment is compared with the new ambient convective coating. With less complicate deposition process and set up, only 40 microliter is used in convective coating compared to 200 microliter used in standard spin coating. The solar cell performance in the ambient convective coating has no significantly different from that in spin coating under nitrogen filled glove box. Convective coating use small amount of solution to create uniform thin film on a substrate while film thickness can be controlled by deposition speed and volume. Therefore, this coating technique has potential in pilot and manufacturing scale. (C) 2017 Published by Elsevier Ltd.
