The functional characterization of the entire solar cell (which demonstrate a marked improvement of photovoltaic parameters) indicated an overall increase of ~90% in the PCE from 1.48% without any ...
Photovoltaic cells, also called solar cells, are devices that create electricity from light. The most common type is made from silicon in a process similar to the way computer chips are made and requires large expensive factories.One possible alternative to silicon cells is dye-sensitized cells, which are less efficient, but are far less expensive to manufacture.

To reveal the interconnected porous microstructure of the PHEA/PEG framework, a freeze-drying technique was employed and the cross-sectional SEM photograph was shown in Fig. 2 a. It was apparent that the resultant PHEA/PEG gel electrolyte was indeed a well-interconnected and microporous framework capable of …

Photovoltaic cells have been successful in the field of clean energy and are now an important means of harvesting clean energy. The tribovoltaic effect is similar to the photovoltaic effect, the only difference is that the tribovoltaic cell converts mechanical energy into electrical energy, instead of light energy to electric energy.
Photoelectrochemical Cell - an overview
Furthermore, two electrolytes were considered in the RK1 cells: (1) Iodolyte electrolyte (Solaronix); and (2) the NPI-optimized electrolyte described in the section ''Photovoltaic properties ...
This novel type of solar cell had an overall efficiency of 7.1–7.9% (under simulated solar light), which is comparable to amorphous silicon solar cells . The separation of the functional-light-absorbing "dye" from the charge carrier transport in the former is the fundamental distinction between this type of solar cell and ordinary cells.
