With this paper, an additional feature is added to the device property portfolio: optical transparency. Results on translucent perovskite modules with selectively tuned levels of transparency are reported by applying the industrially established fabrication process of partial area ablation to high efficiency opaque devices. After process completion, the final devices consist of opaque areas that absorb the light, and transparent areas that permit neutral light transmission. We compare the effectiveness of using two active area removal techniques: mechanical scribing and laser ablation, and determine the factors that limit the maximum transparency and power conversion efficiency. Moreover, we show how the choice of the ablation method and design of the active area removal pattern affect and limit the maximum light utilization efficiency ratio that can be achieved with this fabrication process. The resulting 4 cm(2) translucent modules cover a range of visible light transparency from 7 to 37% with a corresponding power conversion efficiency of 5 to 13%. | Notes: | Rakocevic, L (reprint author), Imec Partner Solliance, Kapeldreef 75, B-3001 Leuven, Belgium. lucija.rakocevic@imec.be | Document URI: | http://hdl.handle.net/1942/26593 | ISSN: | 2050-7526 | e-ISSN: | 2050-7534 | DOI: | 10.1039/c7tc05863b | ISI #: | 000428987500016 | Rights: | This journal is © The Royal Society of Chemistry 2018 | Category: | A1 | Type: | Journal Contribution | Validations: | ecoom 2019 |
