ABSTRACT
A typical hybrid solar cell comprises a large area of inorganic material and an organic conductive absorber, which can be an organic hole conducting material or a blend of organic electron and hole conductors. Two techniques are used to interface inorganic with organic photovoltaic materials. The first method is to deposit a suspension of stabilized inorganic nanoparticles or nanorods in polymer solution; the second method is to deposit porous inorganic architectures, subsequently intercalating organic materials. It is noteworthy that interfacial defects may vary greatly depending on the preparation and deposition conditions of ETL and HTL. The HSCs based on polymer and wide-bandgap semiconductor QDs showed up to 4% PCE by optimizing the morphology of the hybrid layer and stabilizer engineering. It is worth noting that tin oxide-based semiconductor materials are a new class of ETL for organic-inorganic hybrid SCs with high PCE and long-term stability.
