Perovskite solar cell (PSC) is an emerging photovoltaic technology with a striking 25.5% laboratory scale power conversion efficiency (PCE) (NREL, 2020), that has been achieved in less than ten years of research (Jeon et al., 2015, Lee et al., 2012, NREL, 2020).The "perovskite" refers to the hybrid organic–inorganic perovskite absorbers with …
The main difference in operation between silicon solar cells and OSC, and the reason that OSCs lag silicon solar in their commercialization, is that light absorption in organic semiconductor thin films does not lead to efficient generation of free charge carriers, but to the generation of strongly bound excitons having limited diffusion length.
In the 1990s, the layered organic-inorganic halide perovskite was first studied by Mitzi and co-workers for the electronic applications. 18 Until 2009, the first application of hybrid organic …
Efficiency is paramount in enhancing the performance and cost-effectiveness of solar cells.

The results are helpful in simulating the organic–inorganic perovskite thin film solar cells. Following this, we show the application of the device model in typical organic–inorganic perovskite thin film solar cells in Section 4.1 in terms of the effects of the trap states, direct band recombination, surface recombination, and ion migration.
Light trapping structures are a promising method of improving the efficiency of solar cells. We focused on the plasmonic thin-film solar cell. A structure is proposed consisting of an indium tin oxide layer with embedded metal nanoparticles, a hydrogenated amorphous silicon (a-Si:H) layer, and an aluminum (Al) layer. The finite …
