Inverted Planar Perovskite Solar Cells With A High Fill Factor And

Inverted Planar Perovskite Solar Cells With A High Fill Factor And The performance of inverted perovskite solar cells is highly dependent on hole extraction and surface properties of hole transport layers. to highlight the important role of hole transport layers, a facile and simple method is developed by adding sodium chloride (nacl) into poly(3,4 ethylenedioxythiophene):poly(styrenesulfonate) (pedot:pss). the average power conversion efficiency of the. The average power conversion efficiency of the perovskite solar cells prepared on nacl doped pedot:pss is 17.1% with negligible hysteresis, compared favorably to the control devices (15.1%). particularly, they exhibit markedly improved v oc and fill factor (ff), with the best ff as high as 81.9%. the enhancement of photovoltaic performance is.

Figure 1 From Inverted Planar Perovskite Solar Cells With A High Despite the low cost and moderate temperature fabrication process of inverted planar perovskite solar cells (pvscs), the relatively low efficiency (<20%), inferior reproducibility and poor stability significantly hinder their great potential for future commercialization. to address these issues, here we intr. The performance of inverted perovskite solar cells is highly dependent on hole extraction and surface properties of hole transport layers. to highlight the important role of hole transport layers.

It is noted that unlike the n i p single junction cells or p i n top cells in tandem devices where the high energy uv light would be largely filtered by perovskite photoactive layer and then reach the p layer perovskite interface, for single junction p i n perovskite solar cells, the high energy uv photons would first strike at p layer perovskite interfaces and the uv induced interfacial.
