The difference between the organic and the metallic solar cells stems from the difference between the organic and the metallic semiconductors.

The metallic semiconductors have long-term order while the organic semiconductors have molecular short-term order. This leads to the following differences:

The metallic semiconductors have much larger effective mass and therefore they have much larger mobility.

The second major difference is that the dielectric constant of the organic semiconductors is lass than that of the metallic semiconductors

This has a profound effect on the formation of excitons which are bound electron hole pairs needing dissociation energy while the excitons in the organic semiconductors are readily dissociated forming free electrons and holes.

The organic materials have a much larger absorption coefficient of the incident solar radiation and hence it requires only very thin film material to absorb the incident solar radiation. This is one of the main advantage of the organic semiconductors versus the inorganic semiconductors which needs much thicker active layers.

So the organic solar cells are very thin film structures in the order of the few tens of nanometers to few hundreds of Nano meters. Compared to organic semiconductors needing active layer thickness in the order of few micrometers to few hundreds of micrometers.

The organic semiconductors are light weight and flexible compared to the metallic materials.

The metallic solar cells are more stable against the environmental effects than the organic semiconductors.

There is a hybrid type materials which sums up the advantages of both classes of semiconductors. This class the perovskites semiconductors.

Hello Amir Hossein Zakeri ,

In the organic perovskite solar cells, carbon-based organic materials are used as the active layer to produce electrons and holes. Where in the case of inorganic perovskite solar cells, halide-based, metal halide, or non-carbon materials are commonly used as the active layer. In another case, a combination of organic-inorganic elements is used for organic-inorganic perovskite solar cells. Following articles may help:

Is there a metal-halide in both types as a perovskite base?

Apart from supporting layers, the perovskite material (the absorber layer) used in PSCs itself can be hybrid organic-inorganic and all-inorganic types.

Any material taking crystal structure of formula ABX3 is termed as perovskite material. In case of solar cells X is halides ( Cl, Br, I). This halide based perovskite for solar cell application is further of two types:

1. Alkali halide based perovskite-

They are all-inorganic. Here A is alkali monovalent cation such as Cs+, K+, Na+, Rb+ etc

B is divalent cation such as Pb2+, Sn2+, Ge2+ etc.

2. Hybrid organic-inorganic perovskite have organic monovalent cation (A) such as FA+, MA+
