The combination of inorganic and organic semiconducting materials in conjunction forms a hybrid solar cell. Conventional solar architectures involved inorganic materials (largely silicon) which revealed elevated PCEs, but with high production cost. In contrast, the solar cells that mainly involved organic materials have low production costs and via molecular designs and modern synthetic tools, they can be functionalized along with ease of tuning their energy level (Pandey et al. 2016). Therefore, hybrid solar cells perfectly blend the advantageous features of these two technologies and represent an emerging but vastly effective and inexpensive solar technology. Such amalgamation of solar technology is constructed of a heterojunction in combination with c-Si and a-Si fundamental thin layered tools.

The values of photocurrent and photovoltage in basil/ZnO are higher than ZnO/FTO thin films. Voltage vs. time characteristics of basil/ZnO/FTO shows that dye is degrading slowly as the value of photovoltage is decreasing with time. The stability of dye, recombination, and separation of electron−hole (e–h) pair at ZnO−dye interface are the main limiting factors on the efficiency of DSSCs. These results can be very useful to study the life of natural dye and its stability. The maximum open-circuit potential is determined by the gap of dye, but Voc is decreased due to recombination of e–h pair [39,40]. Therefore, the performance of the hybrid solar cell is limited by low photocurrent and fill factor. The low open-circuit potential behavior can be explained further by the detailed understandings of dye absorption and electron–dye recombination. The various interface in the FTO/ZnO/dye/metal leads to low Isc. The protein complex and the ZnO layer are responsible for better efficient dye-sensitized solar cells.

Enhancement of hybrid cell performance has been achieved by obtaining controlled mixtures of nanoparticle/copolymer and using the nonconjugated block copolymer with homogeneous distribution of nanoparticles in the layer.[37,38] Another developed hybrid cell structure is based on a two-layer sandwich structures produced by spin coating. Examples of hybrid organic photovoltaic cells obtained from the solution are nanocomposites consisting of PbS nanoparticle nanoadditives in poly(3-hexytiofen) (P3HT) matrix. An example of modern hybrid solar cell structure is CIS substrate/absorber and buffer layer of organic zinc phthalocyanine (ZnPc), active layer of ZnPc:C60 composite, and a poly (3,4-ethylenedioxythiophene buffers) (polyester)-doped polystyrenesulfonate (PSS) (PEDOT: PSS).[37]
