Tiến bộ gần đây trong lớp vận chuyển electron hai lớp cho các tế bào mặt trời perovskite hiệu quả và tiết kiệm chi phí: một tổng quan
Tóm tắt
Ngày nay, các tế bào mặt trời lai hữu cơ - vô cơ perovskite đặc biệt được ngành năng lượng quan tâm để thiết kế và phát triển các thiết bị quang điện thế hệ mới. Chúng là những vật liệu hứa hẹn nhất cho hiệu suất chuyển đổi công suất cao (PCE) và các tế bào mặt trời giá rẻ. Chúng cũng có thể giải quyết nhu cầu năng lượng hiện tại của xã hội và cuộc khủng hoảng toàn cầu. Trong vài năm qua, hiệu suất chuyển đổi năng lượng (PCE) của các tế bào mặt trời perovskite (PSC) đã tăng nhanh từ 3.8% lên 24.2%. Tuy nhiên, bài tổng quan này tập trung vào sự phát triển gần đây của lớp vận chuyển electron do đây là tham số quan trọng nhất của các tế bào mặt trời perovskite để nâng cao hiệu suất và độ ổn định của thiết bị. Các tóm tắt này thảo luận về kiến trúc thiết bị, lớp vận chuyển electron đơn và đôi, tối ưu hóa lớp vận chuyển electron (ETL), và giao diện lớp hoạt động perovskite cho các tế bào mặt trời perovskite hiệu quả. Hơn nữa, các hiệu ứng doping lên lớp vận chuyển điện tích/lớp cửa sổ của PSC cũng đã được xem xét. Ngoài ra, các vấn đề liên quan đến hiệu suất và độ ổn định của các tế bào mặt trời perovskite halide hữu cơ - vô cơ cũng được thảo luận ở đây. Cuối cùng, nghiên cứu trong tương lai về ETL hai lớp và giao diện lớp hoạt động perovskite cũng đã được đề xuất.
