摘要: | 鈣鈦礦太陽能電池在光電轉換效率上已能夠超過25%,其在製備上的簡便性以及低成本,愈來愈多研究投入於開發量產技術,具有相當大的商業化潛力。雙面透明電極的鈣鈦礦元件亦漸漸受到矚目,鈣鈦礦元件優異的穿透度調節性除了可應用於鈣鈦礦/矽晶串疊型太陽能電池外,亦可應用於手錶、窗戶、螢幕上。在本研究中,我們著手於雙面透明電極鈣鈦礦模組的開發,利用雷射雕刻技術,製造出高效率的模組。 鈣鈦礦電池模組的製造方式是將一整片的電池經由P1、P2、P3三道加工分割成幾塊小元件再將其串聯起來;P1將下電極切斷,P2在吸收層中刮出一通道,P3刮斷上電極,經由此製程完成模組開發。雷射雕刻技術具備加工準確性和細緻性優點,我們自主研發全雷射製程,開發過程中,在室內環境中以單一532nm波長的奈秒雷射進行;透過調整脈衝重疊率以及能量大小,完成三道切割。其中,P2方面需要在元件上刮出一通道以連結上下電極,我們選擇合適的連接寬度,使模組中不發電區域面積最小化,在子元件寬度為固定5mm下,製作出GFF為94%的單向串聯模組。為了確認P2可行性,使用EDS分析表面元素殘留,並用傳輸線法分析其接觸電阻,發現30μm接觸寬度下足夠應用於模組串聯。 最後,於2x2 cm2 的基材上製作串聯兩顆元件的模組,在有效面積光電轉換效率達到12.5%以及72.4%的FF。 The photoelectric conversion efficiency of perovskite solar cells has exceeded 25% since be discovered. Due to its convenience of fabrication and low cost, more and more studies have introduced them to industrial production, which has considerable potential for commercialization. The bifacial transparent electrode perovskite solar cell has gradually considered as a promising candidate. The perovskite device's excellent permeability adjustability can not only be applied on the perovskite/silicon tandem solar cell, but also watches, windows, and screens. In this research, we focused on laser patterning technology of the perovskite modules development with bifacial transparent electrodes and produced a high-efficiency module. Perovskite solar modules are fabricated through monolithic integration method which is established by the so-called P1, P2, and P3 three parallel scribing line. P1 cuts the back electrode, and P2 scribes in the absorption layer to produce an interconnection area between front and back electrode, then P3 cuts off the front electrode. Laser patterning technology has the advantages of processing accuracy and meticulousness. We develop a full laser process applied on module fabrication on our own. During the development process, a single 532nm wavelength nanosecond pulse laser was used in the air environment. Three scribing lines are completed by controlling the pulse overlap ratio and laser power density. For P2 process, it is necessary to scrape a tunnel on the perovskite layer to connect the front and back electrodes. We choose the appropriate connection width to minimize the dead area in the module. When the width of the sub-cells is fixed at 5mm, a module with GFF of 94% is fabricated. In order to confirm the feasibility of P2 process, Energy-Dispersive X-ray Spectroscopy was applied to analyze the residual elements on the surface of connect tunnel and the contact resistance was measured by the transfer line method (TLM). It was found that sub-cells were completely connected in series with a contact width of 30μm in the interconnection area. A micro module with two sub-cells was fabricated on a 2x2 cm2 substrate, and the photoelectric conversion efficiency arrived 12.5% with aperture area . We also arrived a high FF with 72.4%. |
