Thus, bulk heterojunction perovskite solar cells by the CH 3 NH 3 PbI 2.55 Br 0.45 :Zn 2 SnO 4 thin film exhibit over 21.07% power conversion efficiency, which is more than 12% enhancement as compared to that (18.74%) observed from planar heterojunction perovskite solar cells by the pristine CH 3 NH 3 PbI 2.55 Br 0.45 thin film.
We apologise for any inconvenience caused and thank you for your patience. A major limitation to increasing the efficiency of perovskite hybrid solar cells (pero-HSCs) is the fact that the diffusion length of the electrons is shorter than that of the holes.
To date, the power conversion efficiency (PCE) of perovskite solar cells (PSCs) has attained to 25.7 %, which can be competitive with that of silicon solar cells. , , , However, the long-term stability of PSCs lags far behind the lifetime of silicon solar cells.
The bulk perovskite layer is close to intrinsic type [ 10 ]. The very thin ETL and HTL layers are the interfacial layers between the bulk perovskite layer and the contact electrodes [ 11, 12 ]. The structure is equivalent to ETL-i-HTL or HTL-i-ETL.
Halide perovskite solar cells (PSCs) have become the research hotspot in photovoltaic technology for its potential low cost. The certified power conversion efficiency (PCE) of organic-inorganic PSCs has reached 25.5%. However, the commonly used perovskite materials dominated by organic ions will decompose at high temperatures.
This study proposes a concise physics-based mathematical model that explains the effects of bulk and surface recombination on the photocurrent in various perovskite solar cells. Theoretical calculations and experimental results from several perovskite solar cells have been compared to validate the theoretical model.
