“…Solar cells generate energy by electron displacement, this happens when in a multiple layer cell, an electron in the highest occupied molecular orbital (HOMO) absorbs a photon, and by consequence is excited in the lowest unoccupied molecular orbital (LUMO), this generates a bound electron-hole pair called exciton [207]. Extra photon energy dissipates as heat; because of this, an efficient solar cell works in a wide solar spectrum, to create the greater amount of excitons [207]. Excitons are generated due a low dielectric constant of the organic materials [208].…”

“…Exciton diffuse in the donor-accepter interface (D-A) [207]. If the exciton is inside the diffusion range of the organic polymer [209] it can be separated in a free electron and a hole denominated charge carriers [207]. This happens when the exciton meets the electric field within the diffusion range (≤20 nm) [210].…”

“…This happens when the exciton meets the electric field within the diffusion range (≤20 nm) [210]. Charge carriers are swept to their respective electrodes, because of the built-in field [207]. During the diffusion recombination process will happen leading to losses, before reaching the (D-A) interface [208].…”

Solar photoelectric energy converted into electricity requires large surface areas with incident light and flexible materials to capture these light emissions. Currently, sunlight rays are converted to electrical energy using silicon polymeric material with efficiency up to 22%. The majority of the energy is lost during conversion due to an energy gap between sunlight photons and polymer energy transformation. This energy conversion also depends on the morphology of present polymeric materials. Therefore, it is very important to construct mechanisms of highest energy occupied molecular orbitals (HOMO)s and the lowest energy unoccupied molecular orbitals (LUMO)s to increase the efficiency of conversion. The organic and inorganic solar cells used as dyes can absorb more photons from sunlight and the energy gap will be less for better conversion of energy to electricity than the conventional solar cells. This paper provides an up-to-date review on the performance, characterization, and reliability of different composite polymeric materials for energy conversion. Specific attention has been given to organic solar cells because of their several advantages over others, such as their low-energy payback time, conversion efficiency and greenhouse emissions. Finally, this paper provides the recent progress on the application of both organic and inorganic solar cells for electric power generations together with several challenges that are currently faced.

“…The reason for this interest is their greater flexibility as well as easier fabrication, especially over large areas, along with the lower production cost [2,3]. Of special consideration are polymer photovoltaic solar cells (PSCs) [4], which traditionally contain 3 tiers: (a) polymer zone (for photon absorption), (b) region for the production of electron and hole pairs, and (c) a layer for the charges to be carried through to the contacts.…”

The energy scenario today is focused on the development and usage of solar cells, especially in the paradigm of clean energy. To readily create electron and hole pairs, solar cells utilize either photoactive or photosensitive components. A bulk heterojunction (BHJ) is a nanolayer consisting of donor and acceptor components with a large interpenetrated acceptor and donor contact area. In this context, a mix of P3HT and PCBM offers novelty for its use as an acceptor as well as a donor. In the work presented here, we address the mechanism of modelling and characterization of a BHJ-based polymer solar cell. Here, a new design of BHJ polymer solar cells have been designed, modelled, using Silvaco TCAD in the Organic Solar module, and matched with an already assembled device having similar features. Using this model, we have been able to estimate key parameters for the modelled devices, such as the short-circuit current density, open-circuit voltage, and fill factor with less than 0.25 error index compared to the fabricated counterpart, paving the way for fabless polymer solar cell design and optimization.
