Abstrak Objektif. Penggunaan sel surya silikon saat ini masih tergolong mahal serta juga menggunakan bahan kimia yang berbahaya pada proses pembuatannya. Oleh karena itu perlu dikembangkan sel surya alternatif yang berbahan dasar murah dan ramah lingkungan, seperti DSSC (Dye Sensitized Solar Cell). Penggunaan DSSC sangat bagus dikembangkan dikarenakan proses pembuatan yang sederhana, biaya murah serta berbahan dasar organik.. Berdasarkan hal tersebut, perlu adanya pengembangan DSSC menggunakan dye dari ekstrak antosianin dari bahan alam yang banyak terdapat dilingkungan.  Material and Metode. Penelitian ini bertujuan mengetahui karakteristik DSSC menggunakan ekstrak bunga rosella dengan variasi jarak sumber cahaya terhadap DSSC. Karakteristik yang diukur adalah nilai arus dan tegangan serta efisiensi sel.  Sebagai sumber cahaya digunakan adalah lampu halogen 150 watt. Sumber cahaya diletakkan pada jarak 10 cm, 20 cm dan 30 cm. Hasil. Karakterisasi nilai tegangan dan arus DSSC menggunakan cahaya lampu halogen dengan jarak 10 cm terhadap DSSC lebih besar dibandingkan dengan jarak 20 cm dan 30 cm. Hasil pengujian menunjukkan bahwa efisiensi sel yang berjarak 10 cm terhadap DSSC merupakan hasil terbaik arus maksimal (Imax) 0,08 mA, tegangan maksimal (Vmax) 121,7 mV. Kesimpulan. Kinerja dari DSSC dipengaruhi oleh jarak sumber cahaya yang digunakan terhadap sel. Perbedaan nilai efisiensi ini disebabkan oleh besar intensitas cahaya terhadap sel, semakin dekat jarak sumber cahaya semakin besar intensitas cahaya sehingga menghasilkan nilai efisiensi yang besar. Abstrack Objective. The use of silicon solar cells is still relatively expensive and also uses harmful chemicals in the manufacturing process. Therefore it is necessary to develop alternative solar cells that are based on inexpensive and environmentally friendly, such as DSSC (Dye-Sensitized Solar Cell). The use of DSSC is very well prepared because of the simple manufacturing process, low cost, and organic-based. Based on this, the development of DSSC requires the use of dye from anthocyanin extracts from natural materials that are widely available in the environment. Materials and Methods. This study aims to determine the characteristics of DSSC using rosella flower extracts with variations in the distance of the light source to DSSC. The trademarks measured are current and voltage values ​​and cell efficiency. As the light source used is a 150-watt halogen lamp. Light sources are placed at a distance of 10 cm, 20 cm, and 30 cm. Results. Characterization of DSSC voltage and current values ​​using a halogen lamp with a distance of 10 cm to DSSC is more significant than a length of 20 cm and 30 cm. The test results show that the efficiency of cells within 10 cm of DSSC is the best result of maximum current (Imax) of 0.08 mA, maximum voltage (Vmax) of 121.7 mV. Conclusion. The performance of DSSC is influenced by the distance of the light source used against the cell. This difference in efficiency value is caused by the higher intensity of the light to the battery, the closer the distance of the light source, the higher the depth of the sun to produce an immense efficiency value.

Sensitized Solar Cells

Dye-sensitized solar cells (DSSC) are solar cells that has a great potential to be applied as renewable energy conversion. The major advantages of DSSC are the ease of fabrication process and low cost of production. Despite of these advantages, the efficiency of DSSC for converting light into electricity is still low. It is due to charge recombination in DSSC which limits the photoanode performance. Numerous efforts has been carried out to increase the efficiency of DSSC, one of which is by adding reduced graphene oxide (rGO) to titanium oxide (TiO2) to obtain TiO2-rGO nanocomposite. In this study, the synthesis of TiO2-rGO nanocomposites was carried out with concentration of rGO are 0.6, 0.8, and 1.0 wt% to amount of TiO2. We have done some characterizations to confirm the result of synthesized TiO2-rGO. UV-Vis measurement shows the addition of rGO has widened the absorption up to 400 nm. The FT-IR spectrum confirms that the rGO peaks appears at wavelength of 1400, 1600, dan 1700 cm-1 which exhibited the vibration C-O, C=C, and C=O stretching from COOH groups, respectively. The highest efficiency of DSSC with photoanode TiO2-rGO nanocomposite is 0.09% which was obtained from 0.8 wt% of rGO.

Dye sensitized solar cell (DSSC) is a new class of low-cost solar cell, that belongs to third generation solar cells in thin film based. It is based on a semiconductor formed between a photo-sensitized anode and an electrolyte, known as photoelectrochemical system. A lot of research has been conducted due to their interesting potential for low-cost, lightweight, disposable and having cell efficiency up to 10%. This paper reports the fabrication of dye sensitized solar cells using TiO2 nanoparticles and chlorophyll as active layer. TiO2 nanoparticles were prepared by sol-gel method while the chlorophyll was extracted from Pandanus amaryllifolius (Pandan leaf). TiO2 film was prepared on ITO coated glass using dip coating technique and then immersed overnight in the chlorophyll solution. An electrolyte solution composed of PC-LiClO4 was injected into the cell before sealed using glass that was coated with Pt as top electrode. An active area of 4.48 cm2 was fabricated by black masking the front side. The performance of the device was studied by observing the current-voltage characteristics of the device in dark at ambient temperature and under illumination of 100 mW/cm2 light. It was found that the device showed rectifier property in the dark and able to generate electrical current under light.

This project is to investigate the counter electrode material from two different carbon sources to fabricate dye sensitized solar cell (DSSC). The carbon sources are extracted from battery and pencil lead. The method to prepare the DSSC is through the conventional Dr.Blading method. The same method is also used for the counter electrode which uses carbon from recycle batteries, the carbon from pencil lead are scribbled onto the ITO glass to get a uniform coating. Both thickness of the counter electrode vary accordingly. The solar cells are then placed under outdoor solar irradiation and the output is taken every 10 minutes. Based on observation, the solar cells which have the carbon from batteries shows higher cell efficiency which is 8.2 % with lower FF of 0.78, compared to by using the pencil lead, the cell efficiency is only 7.23% but with a higher FF of 0.93.

The Cost

Solar power system is one of the renewable sources that will be used to produce electricity because of its characteristics such as consumed free source of sun light, less maintenance needed for the system and free of charge for usage electricity. One of the main disadvantages is the initial cost of the equipment used to harness the suns energy especially the cost of solar panel. In Malaysia, the cost of solar panel are relatively high because the solar panel are imported from overseas and the materials used in existing solar panel is very expensive. Therefore the proposed solar cells that will be used is natural dye sensitized with photovoltaic material. The scope of this research is to full fill the demand of low cost and to abundance, renewable material that could be used for energy conversion solar cell. The circuit connections of solar cells are in series and the performance of the dye sensitized cells would be based on the intensity of the sunlight illumination. The measurement of solar cell are conducted using 10 dye sensitizied cells connected in series circuit arrangement and the performance for this design are evaluated based on the generated potential (V) upon sunlight illumination at noon and evening for certain period of time. The result obtained from this research shows that the performance of series circuit connection of the dye sensitized solar cell is comparable with the silicon solar cell.

Sensitized Solar Cells

Although the price of dye-sensitized solar cells is lower than other solar cells, they still contain some high-cost materials, such as transparent conductive substrates, dyes (ruthenium dyes, organic dyes, etc.), and platinum counter electrodes. To solve this problem, a dye-sensitized solar cell based on hibiscus leaching solution and carbon black–silver electrodes was prepared by screen printing. The prepared low-cost dye-sensitized solar cells were flexible. The open-circuit voltage (Voc) of the obtained dye-sensitized solar cell is 0.65 V, the current density (Jsc) is 90 μA/cm², and the fill factor (FF) is 0.241.
