Dalam laporan ini, ciri-ciri sel suria telah dinilai dengan doping lapisan aktif CH3NH3PbI3 (MAPbI3) dengan 3.0 vol% dan 6.0 vol% ion kalium (KI) dalam sel suria perovskite berstruktur songsang (PSC). Plot Tauc bagi ciri-ciri penyerapan dan ciri potensi pengionan menunjukkan bahawa hujung atas jalur valens beralih sebanyak 0.21eV ke arah cetek daripada -5.34eV kepada -5.13eV, dan jurang jalur tenaga berkurangan daripada 1.530eV kepada 1.525eV . Juga, ukuran XRD menunjukkan bahawa pemalar kekisi menurun daripada 8.96Å kepada 8.93Å apabila KI didop. Penurunan dalam pemalar kekisi menunjukkan bahawa sebahagian daripada tapak A digantikan daripada ion metilammonium (MAI) kepada KI. Dalam ciri JV sel suria, nilai min Jsc bertambah baik daripada 7.0mA/cm2 tanpa KI hingga 8.8mA/cm2 dengan 3.0 vol% KI didop dan kepada 10.2mA/cm2 dengan 6.0 vol% daripada doped KI. Hasilnya, nilai min kecekapan penukaran kuasa (PCE) tanpa KI ialah 3.5%, tetapi nilai min PCE meningkat kepada 5.2% dengan 3.0 vol% KI doped dan kepada 4.5% dengan 6.0 vol% KI doped. Oleh itu, ia telah menunjukkan keberkesanan doping KI kepada MAIPBI3, yang berfungsi sebagai lapisan aktif, walaupun dalam PSC berstruktur songsang.

Abstract: In this report, solar cell characteristics were evaluated by doping the active layer CH3NH3PbI3 (MAPbI3) with 3.0 vol% and 6.0 vol% of potassium ion (KI) in an inverse-structured perovskite solar cells (PSCs). The Tauc plots of the absorbance characteristics and the ionization potential characteristics show that the top end of the valence band shifted by 0.21eV in the shallow direction from -5.34eV to -5.13eV, and the energy band gap decreased from 1.530eV to 1.525eV. Also, the XRD measurements show that the lattice constant decreased from 8.96Å to 8.93Å when KI was doped. The decrease in the lattice constant indicates that a part of the A site is replaced from methylammonium ion (MAI) to KI. In the J-V characteristics of the solar cell, the mean value of Jsc improved from 7.0mA/cm2 without KI to 8.8mA/cm2 with 3.0 vol% of KI doped and to 10.2mA/cm2 with 6.0 vol% of KI doped. As a result, the mean value of power-conversion efficiency (PCE) without KI was 3.5%, but the mean value of PCE improved to 5.2% with 3.0 vol% of KI doped and to 4.5% with 6.0 vol% of KI doped. Thus, it has shown that it is effective to dope KI to MAIPBI3, which serves as the active layer, even in the inverse-structured PSCs.
