AbstractIn order to achieve the widespread use of HIT (Hetero-junction with I etero-Intrinsic T ntrinsic Thin-layer) solar cells, it is important to reduce the power generating cost. There are three main approaches for reducing this cost: raising the conversion efficiency of the HIT cell, using a thinner wafer to reduce the wafer cost, and raising the open circuit voltage to obtain a better temperature coefficient. With the first approach, we have achieved the highest conversion efficiency values of 22.3%, confirmed by AIST, in a HIT solar cell. This cell has an open circuit voltage of 0.725 V, a short circuit current density of 38.9 mA/cm2 and a fill factor of 0.791, with a cell size of 100.5 cm2. The second approach is to use thinner Si wafers. The shortage of Si feedstock and the strong requirement of a lower sales price make it necessary for solar cell manufacturers to reduce their production cost. The wafer cost is an especially dominant factor in the production cost. In order to provide low-priced, high-quality solar cells, we are trying to use thinner wafers. We obtained a conversion efficiency of 21.4% (measured by Sanyo) for a HIT solar cell with a thickness of 85μm. Even better, there was absolutely no sagging in our HIT solar cell because of its symmetrical structure. The third approach is to raise the open circuit voltage. We obtained a remarkably higher Voc of 0.739 V with the thinner cell mentioned above because of its low surface recombination velocity. The high Voc results in good temperature properties, which allow it to generate a large amount of electricity at high temperatures.

Absorption Window

Light harvesting for generation of electric energy is one of the most important research topics in applied sciences. First, for an efficient harvesting one needs a material with a broad light absorption window having a strong overlap with the sunlight spectrum. Second, one needs an efficient conversion of photoexcited carriers into produced current or voltage which can be used for applied purposes. The maximum light conversion coefficient in semiconductor systems is designated by so called Shockley-Queisser law, which is around 32% for an optimal bandgap value of 1,2–1,3 eV. However the efficiency may be increased using a solutions based on semiconductor nano materials such as quantum dots. Solar cells based on such a structures are included in the group of 3rd generation solar sell. 3rd generation solar cell encompasses multiple materials as a base of cell, such as: perovskite, organic, polymers and biomimetics. The most promising and in the same time most discussed are quantum dots and perovskite. Both material has a potential to revolutionize the solar cell industry due to their wide absorption range and high conversion coefficient. Nonetheless before the most common used material in photovoltaic namely silicon is replace one must overcome few major issues such as: stability and lifetime for at least 5 to 10 years or more, manufacturing process for a large surfaces and low production cost as well as recycling after the time of optimal use.

<p class="AbstractEnglish"><strong>Abstract:</strong><span> </span>One necessary application of the Solar system is a water pump power supply. The solar cells typically designed solely to drive one load pump, to boost water to a high place, over one motor-pump ought to be thought of. Several completely different or similar water pumps are generated by separate solar cell sources, or the solar cells are combined for the total pump. This final project investigates once two water pumps generated by solar cells are combined, with the condition of solar radiation in Bandung. This final project analysis shows that for a special pump let alone a combined solar cell supply has a bonus. At low insulation, the pump will carry up water and may stop the flow of different pumps to enhance the performance of the opposite pump. As a solar module utilized by Arco Solar, it's the efficiency of 8.8%. Pump one efficiency of 26%, and for pump two the efficiency reaches 14%.</p><p class="AbstrakIndonesia"><strong>Abstrak: </strong>Salah satu penerapan penting dari sistem surya, adalah sebagai catu daya pompa air.

<p style="text-align: justify;">The research of solar cell with using dye from natural materials as a sensitizer in a dye-sensitized solar cell (DSSC) continues to grow. One advantage of the DSSC is does not require a material with high purity so that the production cost is relatively low. This research aims to analyze the characteristics of the absorption band of teak leaf extract. Extraction of teak leaves dissolved in a mixture of ethanol and acetic acid with a variation ratio of 1: 0, 1: 1 and 5.66: 1, resulting in a solution of each color reddish yellow, reddish brown and dark red. Absropsi test results with UV-Vis spectrometer showed that there are peaks in the absorbance in the visible region, ie at wavelengths between 500 nm to 560 nm. This shows that the dye material of teak leaf extract may work or absorb the green color. While absobption other peaks are also found in pektrum wavelength of 580 nm, 600 nm and 660 nm, each of which can absorb the green color yellow, orange and red. ©2016 JNSMR UIN Walisongo.

Ultrasonic Standing Wave

Nowadays solar energy receives more and more attention for its clear, non-pollutant and renewable characteristics. Although the production cost of electricity by solar cell is much higher than those by fossil fuels currently, solar cell has partly substituted traditional energy and be used in some fields. Silicon wafer surface texture act an important role in solar cell, which can trap the incident lights and influence the photoelectric conversion. In this paper, a new method using ultrasonic standing wave is present based on the previous researches. The acid molecules are droved to distribute regularly in terms of the standing wave. Then regular morphology can be textured on the surface of mc-Si by the acid molecules etching with silicon. SEM experiment illustrate the present method can texture regular morphology on the surface of multi-crystalline silicon (mc-Si) , also the antireflection of 9.4% is much lower than that of traditional acid etching.
