石墨烯/鉑奈米粒子於金字塔薄型矽上之太陽電池分析
Analysis of Graphene coupled with Pt nanoparticles/Pyramidal Thin Silicon Solar Cells
摘要
石墨烯具有有多項優異性能，包括高導電性，高透明度，良好的化學穩定性和的機械柔韌性，在光電器件如光感測器、太陽電池，電晶體應用中具有巨大的潛力。 藉由有限差分時域（FDTD）方法對Pt奈米粒子石墨烯/金字塔形薄型矽太陽能電池進行了模擬，以提高轉換效率，在三種不同顆粒大小下的比較，具有10nm Pt顆粒大小的太陽能電池表現最佳，由於表面電漿共振展現出明顯增強的電場強度，從效率5.3%提高至6.14％。 在此採取還原氧化石墨烯旋塗於自製的金字塔薄型矽基板上製作溶液製程的石墨烯太陽電池，經由調整旋塗佈部機次數與轉速來控制薄膜分佈及品質，並旋塗鉑奈米粒子溶液達成表面電漿共振之效果。經由各種量測分析證實其效果，未來可透過表面電漿共振的改善，提升石墨烯元件的發展與應用。

Graphene with excellent properties, including high electrical conductivity, high transparency, well chemical stability, and remarkable mechanical flexibility has great potential in applications of optoelectronic devices, such as photodetectors, solar cells, and transistors. Simulation of graphene/pyramidal thin Si solar cell with Pt nanoparticles to improve the conversion efficiency was performed by the finite-difference time-domain (FDTD) method. solar cell with 10nm Pt nanoparticles shows obviously enhanced electrical field intensity due to surface plasmon resonance, are the efficiency was improved from 5.3% to 6.14 %. Here, the graphene solar cell in the reduced graphene oxide is spin-coated on the pyramidal thin silicon substrate to prepare a solution process is controlled, the film distribution and quality are controlled by adjusting the number and rotation speed of the spin coating machine, the effect of surface plasma resonance is achieved by spin coating a platinum nanoparticle solution. It is confirmed by various measurement and analysis that it can be improved in the future and the contribute to the development and application of graphene components.
