Organic Bromide Salts Interface Modification for High-Efficiency Perovskite Solar Cells with Printed Carbon Electrode

Recent Advances in Poly(3‐hexylthiophene) and Its Applications in Perovskite Solar Cells

“…[ 102 ] A MABr‐modified PSC module was also fabricated recording a 13.2% PCE at a 12 cm 2 area. [ 131 ] Further improvements were reported by Ren et al's previously mentioned work with a 50 cm 2 fully printed module achieving a high 17.05% PCE. [ 95 ]…”

“…[ 118 ] Tian et al reported a MABr‐modified perovskite surface with P3HT HTL in carbon electrode‐based PSCs achieving 19.22% PCE. [ 131 ] The modified structure had an enhanced hole extraction and reduced recombination and defect density, with better energy‐level matching leading to enhanced performance. [ 131 ]…”

Boosting the fill factor and open-circuit voltage of carbon-based perovskite solar cells with a graphene co-doped P3HT/NiOx hole-transporting bilayer

“…[8][9][10] However, in the past years, the PCEs of C-PSCs have increased slowly, and are mostly in the range of 10-20%. [11][12][13][14][15][16][17][18][19][20] The relatively low PCEs of C-PSCs are primarily ascribed to the mismatched valence band offsets and lack of electron-blocking capability between the perovskite and carbon-electrode, resulting in inefficient hole extraction, serious non-radiative recombination loss and an open-circuit voltage (V oc ) deficit. [21][22][23][24] Promisingly, this issue can be overcome by inserting a holetransporting layer (HTL) between the perovskite layer and carbon-electrode.…”
