The parameters which involved for the rotation spectrum are molecular mass, inertia moment, quantum numbers and angular momentum orbital. Made a pitch for a molecular spectrum rotation and inertia moment will be used methods from concept classical mechanics. Quantum mechanical used for determining angular momentum orbital. The spectral energy was counted for a molecular rotation and i.e and . Specific electromagnetics radiation for the energy absorption spectrum and emiting diatomic molecular at the moment that molecular vibrating were in the region spectrum infrared, whereas if the molecular rotated then its on the far infrared and microwave region. Transition which emited measured up by selection rules that only commit for the quantum numbers change as many as one unit, where identics with as the quantum number for one atomic hidrogen. was a quantum number take the values .Transition which emited doesnât have all the same energy, but rather form a series energy which descend (or a series which go up wave length).]]>

<![CDATA[[Computation and modeling] The current solar cell technology is a technology developed by a process that is cheaper and easier in manufacturing. The solar cells sensitized by a dye below abbreviated writing that the DSSC is often also called Grätzel cells or whether the writing in Indonesian to be Sel Surya Berbasis Pewarna Tersensitisasi (SSPT). DSSC is a potential candidate in as a third generation of solar cells (coming soon) because it does not require a material with a high degree of purity so that a low-cost production process. Dye used as a sensitizer can be either synthetic or natural. Metal-based organic dye complex ruthenium using synthetic (it is expensive), but it contains heavy metals that harm the environment. To reduce the cost of DSSC develops organic based on material sensitizer. DSSC using the same principles for the process of photosynthesis that behave as a chlorophyll dye that absorbs light and produces carrier.The effectiveness of DSSC is no doubt that reaching more than 10% but with using this expensive type which is ruthenium complex metal-based organic. It is necessary to study massive research, a material awareness survey that has good performance, environmental costs. In this study will be carried out using DSSC senduduk fruit dye (Melastoma malabathricum) manufacturing and oxide semiconductors are nano materials (nanocrystals) TiO2 anatase gradually the solvotermal techniques.]]>

<![CDATA[The aim of this research is to finding out modeling nanostructure solar cell SC with count in electron energy level on the conduction band. Divais photovoltaic nano i.e quantum dot QD and quantum well QW performing wide range transition of electron which can be controlled by the distribution range area suitably of the size dimension QD. QD gives ability absorbance of the ligth where created electron hole coupling which located in the dot. Transition electron in the QD be significant exceed thermal energy and cannot inducted by the fonon thermally while transition hole be simply inducted by the phonon acoustik thermal.Method of this research are concept and computation for accounting energy level. The concept which be used is DEK. The thickness well ð¿ð¤ is small enough (10ðð or less), the set of level energy discret will be in the well and have hinges at the effective mass and the well thickness i.e ð¸ð rising with reduction ðâ or ð¿ð¤. Maximum energy ð¸1 = 3,77 à 104ðð at the thickness layer ð¿ð¤ = 0,1ðð. Maximum energy ð¸2 = 1,51 à 105ðð at the ð¿ð¤ = 0,1ðð. âð¸ is difference magnitude energy in the starting point 0,1ðð i.e 1,13 à 105ðð and in the last thickness QW i.e 10ðð is 1,13 à 101ðð. Therefore transition electron in the QW be significantly exceed thermal energy and cannot inducted by the phonon thermal.]]>

<![CDATA[Teknologi sel surya saat ini adalah teknologi yang dikembangkan sebgai energi alternatif. Dye Sensitized Solar Cells DSSC merupakan salah satu kandidat yang berpotensi sebagai sel surya generasi mendatang dikarenakan ia tidak memerlukan material dengan tingkat kemurnian tinggi sehingga biaya produksi yang rendah. Dye yang digunakan sebagai sensitizer dapat berupa sintetik maupun alami. Dye sintetik menggunakan organik logam berbasis ruthenium komplek (jenis ini mahal), selain itu mengandung logam berat yang berpengaruh buruk pada lingkungan. Untuk mengurangi biaya dikembangkanlah DSSC berbasis organik pada material sensitizernya. DSSC menggunakan prinsip yang sama dengan proses fotosintesis yaitu dye bertingkah laku seperti klorofil yang menyerap cahaya dan memproduksi carrier. Efisiensi mencapai di atas 10% tetapi dengan menggunakan ruthenium. Maka diperlukan penelitian yang secara besar-besaran mencari, menginvestigasikan material sensitizer yang mempunyai performansi baik, murah dan aman bagi lingkungan. Dalam penelitian ini akan dilakukan fabrikasi DSSC dengan menggunakan dye buah senduduk (Melastoma Malabathricum ) dan semikonduktor oksidanya adalah nanokristal TiO2. Efisiensi yang terhitung adalah 9,06%.]]>
