Dataset on the absorption of PCDTBT:PC 70 BM layers and the electro-optical characteristics of air-stable, large-area PCDTBT:PC 70 BM-based polymer solar cell modules, deposited with a custom built slot-die coater.

The data presented in this article is related to the research article entitled "Fabrication of air-stable, large-area, PCDTBT:PC ₇₀ BM polymer solar cell modules using a custom built slot-die coater" (D.I. Kutsarov, E. New, F. Bausi, A. Zoladek-Lemanczyk, F.A. Castro, S.R.P. Silva, 2016) [1]. The repository name and reference number for the raw data from the abovementioned publication can be found under: https://doi.org/10.15126/surreydata.00813106. In this data in brief article, additional information about the absorption properties of PCDTBT:PC ₇₀ BM layers deposited from a 12.5 mg/ml and 15 mg/ml photoactive layer dispersion are shown. Additionally, the best and average J-V curves of single cells, fabricated from the 10 and 15 mg/ml dispersions, are presented.
