Restores in the photoelectric parameters of the aging silicon solar cells by thermal annealing and ultrasonic treatment

TL;DR: In this article, the photoelectric parameters of mono-crystalline silicon solar cells degraded under gamma radiation can be significant recovered by MHz-frequency ultrasonic treatment (UST) under AM 1.5 illumination condition.
Abstract: To simulate and accelerate of the aging effects, silicon solar cells were exposed to the different doses of co 60 gamma radiation. The current-voltage (I-V) characteristics of mono-crystalline solar cells under AM1.5 illumination condition were studied before and after the gamma irradiation. Experimental results showed that the solar cell parameters such as open circuit voltage (V oc ), short circuit current (I sc ) and efficiency (η) decrease with the increase of the gamma radiation doses. The photoelectric parameters of mono crystalline silicon solar cells degraded under gamma radiation can be significant recovered by MHz-frequency ultrasonic treatment (UST). The performance of UST to restores of the aged silicon solar cells parameters compared to thermal annealing method has been shown in this paper.

TL;DR: In this article, the electrical parameters of degraded silicon solar cells can be significantly recovered by ultrasonic treatment (UST), which is related to a redistribution of the radiation defects and an increase in the homogeneity of a solar cells crystal structure.
Abstract: In the lifetime of solar cells and under normal operating conditions, electrical parameters of solar cells are degrading continuously because solar cells are ageing during outdoor exposure, which could deteriorate their electrical characteristics. In this paper, to simulate and accelerate the effects of aging, solar cells are exposed to the different doses of gamma radiation, since gamma radiation and aging produces similar effects in semiconducting devices. The electrical parameters of degraded silicon solar cells can be significantly recovered by ultrasonic treatment (UST). The restores of the silicon solar cells parameters such as efficiency (η), open circuit voltage (V oc ), short circuit current (I sc ), among other, after ultrasonic treatment is related to a redistribution of the radiation defects and an increase in the homogeneity of a solar cells crystal structure.

TL;DR: In this article, the effects of thermal annealing on bulk-heterojunction organic solar cells based on a thin film blend of poly(3-hexylthiophene-2,5 diyl) (P3HT) and [6,6]-phenyl-C61 butyric acid methyl ester (PCBM) are discussed.
Abstract: The main focus of this review article is to introduce the reader to the advantage and limitation of organic solar cells and to understand how the thermal annealing process could improve performance of organic solar cells. The article explores the operation principles of organic photovoltaic (OPV) device and reviews the effects of thermal annealing on bulk-heterojunction organic solar cells based on a thin film blend of poly (3-hexylthiophene-2,5 diyl) (P3HT) and [6,6]-phenyl-C61 butyric acid methyl ester (PCBM). It focuses on changes in the physical film properties, the electronic performance of devices, as well as the link between film structure and electronic performance during a thermal annealing process. Analysis of film and electrical characteristics, as a function of thermal annealing parameters, indicates that a balancing is established. The balancing between charge conduction and excitonic dissociation leads to the establishment of optimal annealing conditions for maximized electronic performance. Additionally, the report highlights research areas that require attention for future development of this technology.
