The research was conducted to explain how to design a simulation of Solar tracker on Wind-Solar hybrid technology. The simulation were carried out with proteus software simulation. Solar tracker has four LDR sensors and an Arduino Uno Microcontroller which assist the Solar tracker to estimating position of the sun to use a servo motor for solar cell movement. For the result, When the upper light intensity (LDR 1 and LDR 2) is greater than the bottom (LDR 3 and LDR 4), solar cell will move upwards, and vice versa. When the light intensity of the left (LDR 1 and LDR 3) is greater than the right (LDR 2 and LDR 4), solar cell will move to the left, and vice versa. From the research, it could concluded that Solar Tracker can be applied to Wind-Solar technology solar cells

Carbon nanotube bundles were precisely grown atop a p-type silicon wafer that had been treated with catalysts to produce geometries that resemble three-dimensional nano-models to extract more power from the sun. The embedded carbon nanotubes bundles on silicon wafer promise more opportunity for each photon of sunlight to interact with resulting solar cell, as a result of increase of surface area available to produce electricity. The paper discusses morphology of grown nanotubes on silicon wafer along with future prospects of Si-CNTs fabricated solar cells.

Indoor Conditions

Most commercially available photovoltaic solar cells are crystalline silicon cells. However, in indoor environments, the efficiency of Si-cells is poor. Typically, the light intensity under artificial lighting conditions is less than 10 W/m² as compared to 100-1000 W/m² under outdoor conditions. Moreover, the spectrum is different from the outdoor solar spectrum and there is more diffuse than direct light. Taken into account the predicted cheaper costs for the production of organic solar cells, a possible niche market for organic PV can be indoor applications. In this article, we study the properties and suitability of several bulk heterojunction organic solar cells (with distinct different absorption spectra) for different indoor conditions. We simulate different light environments and use a silicon solar cell as reference. Depending on the required power for the indoor device, we determine minimum requirements for the environment (light intensity and indoor spectrum) and for the organic solar cell (absorption spectrum and surface area). In this way we determine the appropriateness and conditions for a competitive indoor use of organic solar cells.

Abstrak- The study about fill factor and efficiency solar cell have been done with an automatic drive machine that rotates the surface of the solar cell following the movement of the light source from 0° up to 90° compared without automatic drive.  The test results are then implemented to determine the fill factor and efficiency in variations in light intensity. In this study, polycrystalline solar cell type (99 × 69) mm2, the Philips 100W/220V light bulb at a distance of 18 cm and the driving machine is controlled through an Arduino Uno R3 microcontroller. Data acquisition of current and voltage is carried out with the help of DCP-BTA current and VP-BTA voltage probes that are connected to the mini labquest transducer and displayed to a computer through loggerpro software. The result show that it has been successfully designed an automatic driver of a solar panel (99 × 69) mm2  with an Arduino Uno R3 microcontroller and a logger pro software as data acquisition software. The using solar cell automatically driven can improve the accuracy and precision of current and voltage readings so the fill factor might be increased up to 10% while the efficiency of solar cells does not change. Variations in light intensity can increase the fill factor and efficiency of solar cells. Fill factor and efficiency have an exponentially relationship to light intensity.

Solar Tracker

A new solar tracker is designed and tested. The solar tracker is an all-weather solar machine aiming at the sun automatically with high precision. An embedded CPU is used as the control unit, calculating the position of the sun according to geography. Two light intensity detecting chips are used; one of them is to measure the ambient light intensity while the other is to check whether the tracker is directed to the sun well. The result of the first chip determines whether the second chip will be put into use. In this way it is guaranteed that the tracker operates well either with sufficient ambient light or not. Two step motors are used to drive the solar energy collector. The solar tracker has been produced and tested, showing satisfying tracking effect.

Pengembangan dan penggunaan energi terbarukan merupakan kebutuhan penting di masa depan demi meminimalisir emisi karbon dan untuk membatasi perubahan suhu rata-rata global. Energi terbarukan yang dapat digunakan salah satunya adalah energi surya. Pemanfaatan energi matahari ini dapat dilakukan melalui energi listrik yaitu menggunakan teknologi dengan Solar Cell. Sel surya atau solar cell dapat mengkonversi energi cahaya matahari menjadi energi listrik. Salah satu kendala dalam konversi energi surya adalah kurang optimalnya penerimaan energi matahari akibat penempatan solar cell yang hanya menghadap satu arah saja atau bersifat statis. Maka dari itu, perlu dibuatnya suatu sistem yang dapat memodifikasi solar cell selalu mengikuti arah bergeraknya cahaya matahari. Energi yang dihasilkan dari solar cell akan maksimal apabila solar tracker selalu tegak lurus terhadap arah datangnya sinar matahari. Pada alat ini dibuat solar tracker menggunakan mikrokontroler Arduino Uno dalam mengendalikan pergerakan dari motor servo, motor stepper dan sensor LDR dalam mengikuti pergerakan cahaya matahari. Hasil analisa menunjukkan bahwa daya yang diperoleh Solar Panel yang mengikuti pergerakan cahaya matahari (Solar Tracker) lebih besar dibandingkan dengan Solar Panel pada posisi tetap. Produksi energi pada sistem dinamis dengan menggunakan servo 33% lebih besar dibandingkan dengan statis, sedangkan yang menggunakan stepper 36% lebih besar daripada solar cell dengan kondisi statis.

A novel optically powered microactuator is developed via the integration of a thin film piezoelectric microactuator with a micro-solar cell on the same chip. The integrated microactuator has an overall area of 2×2 mm2 and is less than 0.25 mm in thickness. The paper presents the details of fabrication and preliminary experimental results confirming the optical actuation. The solar cell is fabricated by doping a n-type dopant in a p-type silicon wafer. The thin film piezoelectric microactuator is fabricated alongside the solar cell via the solgel method. The microactuator prototypes are tested for optical actuation under low light intensities in the range 0.1-1.26 W/m2, and corresponding center point displacements of the actuators and the photovoltages output by the solar cells are measured. An unpoled microactuator prototype produced a maximum displacement of 31 nm corresponding to an input light intensity 1.26 W/m2.
