以近紅外光加熱技術製備鈣鈦礦太陽能電池

鈣鈦礦太陽能電池的製程中，通常以加熱板進行熱處理的步驟，但受限於玻璃熱傳導較慢，因此加熱時間往往需要較長時間（數十分鐘）才能達到最佳的材料性質。本研究以近紅外光快速加熱技術應用於鈣鈦礦太陽能電池製程上，可將氧化鎳薄膜及兩步驟製備鈣鈦礦薄膜的熱處理時間，分別從900秒及1500秒縮短至50秒及30秒；除此之外，也將近紅外光加熱技術結合狹縫式塗佈法，製備大面積鈣鈦礦太陽能電池，在溶液中加入正丁醇幫助近紅外光波段的吸收，可以幫助鈣鈦礦前驅物溶液快速揮發，並得到12公分×12公分的高均勻性鈣鈦礦薄膜，其製備成的電池最高效率可達14.30%，加熱時間也縮短至只需14.5秒。本研究開發了近紅外光加熱技術製作鈣鈦礦太陽電池，此技術大幅度的提升了鈣鈦礦太陽電池量產速度，有助於未來鈣鈦礦太陽電池的商業化進程。

For manufacturing perovskite solar cells, we often use heat the perovskite layer by using a hot plate. Due to the limited heat conduction of glass, the perovskite layer is often taken long heating time (tens of minutes) to achieve the optimal properties. In this study, we applied a rapid heating technology of near-infrared (NIR) irradiation to the manufacturing process of perovskite solar cells. By using the NIR irradiation, the heating time of nickel oxide film and perovskite film fabricated by two-step method can be shortened from 900 s and 1500 s to 50 s and 30 s, respectively. In addition, we also integrated the NIR heating technology with slot-die coating process to fabricate large-area perovskite solar cells. We added n-butanol to the perovskite precursor to increase the near-infrared energy absorption, facilitate the evaporation of the solvent system and film formation, and accelerate the crystallization of perovskite. The heating time can be shortened to 14.5 s, and a high-quality uniform perovskite film over an area of 12 cm x 12 cm can be prepared. The highest PCE of the large-area perovskite solar cells can reach to 14.30%. Our research has developed a near-infrared irradiation technology to rapidly manufacture large-area perovskite solar cells, and this technology would facilitate the commercialization of perovskite solar cells in the future.
