Photovoltaic Characteristics

We investigated the effects of irradiation beam conditions on the performance degradation of silicon and triple-junction solar cells for use in space. The fluence rates of electron and proton beams were varied. Degradation did not depend on the fluence rate of protons for both cells. A higher fluence rate of electrons caused greater degradation of the Si cell, but the dependence was due to the temperature increase during irradiation. Two beam-area expansion methods, defocusing and scanning, were examined for proton irradiation of various energies (50 keV–10 MeV). In comparing the output degradation from irradiation with defocused and scanned proton beams, no significant difference in degradation was found for any proton energy. We plan to reflect these findings into ISO standard of irradiation test method of space solar cells.

Significant Difference

This research aims to determine the significance of the difference in science learning results between the group of fifth-grade students in Gugus I Elementary Schools, North Kuta District, in the school year of 2017/2018, that take lessons with the multimedia-assisted probing-prompting learning model and the group of students that take lessons with the conventional learning. The design of this research is a quasi-experimental research with the nonequivalent control group design. The population of this research are all the fifth-grade students of Gugus I Elementary Schools in North Kuta District that still implement the KTSP, which consists of 10 classes with a total of 339 students. The sampling is conducted using the random sampling technique. The sample in this research are the students of class VB in SD (Elementary School) No.7 Dalung, with 36 students as the experiment group and the students of class VB in SD No.4 Dalung with 28 students as the control group. The data collection is conducted using the test method in the form of the multiple choice objective test. The science learning results are analyzed using the t-test. Based on the average the experiment groups =80,89 > the control group =72,85, which means that the multimedia-assisted probing-prompting learning model has an influence on the science learning result. Based on the hypothesis test, tvalues =4,517> ttable =2,000, with dk=62 and a significance level of 5%. Based on the test criteria, H0 is rejected and Ha is accepted. Thus, it can be interpreted there is a significant difference the science learning result between the group of students that were taught using the multimedia-assisted probing-prompting learning model and the students that were taught using the conventional learning. It can be concluded that the the multimedia-assisted probing-prompting learning model has an influence on the science learning result of the fifth-grade students in Gugus I Elementary School, North Kuta District, in the school year of 2017/2018.

Photovoltaic Characteristics

Hybrid photovoltaic concepts based on a nanoscale combination of organic and inorganic semiconductors are promising way to enhance the cost efficiency of solar cells through a better use of the solar spectrum, a higher ratio of interface-to-volume, and the flexible processability of polymers. In this work, two types of thin film solar cells have been developed. In both types of solar cells, poly-N-vinylcarbazole (PVK) is used as electron donor, cadmium sulfide (CdS) and titanium dioxide (TiO2) nanocrystals are used as electron acceptors, respectively. Since TiO2 has a wide band gap and can only absorb UV light, in the second type of solar cell, ruthenium dye is used as photo-sensitizer. The preliminary results of photoconductive and photovoltaic characteristics of these two inorganic-organic composites are presented.
