Solar Cells: A Guide to Theory and Measurement
Existing types of solar cells may be divided into two distinct classes: conventional solar cells, such as silicon p−n junctions, and excitonic solar cells, XSCs. Most organic-based solar cells, including dye-sensitized solar cells, DSSCs, fall into the category of XSCs. In these cells, excitons are generated upon light absorption, and if not created directly at …
Polycrystalline perovskite films have many fatal defects; defect passivation can improve the performance of perovskite solar cells (PSCs). In this study, the defects in perovskite films are passivated by introducing the pseudohalide salt CsPF6 into the films. Because the ionic radii of Cs+ and PF6– are close to those of FA+ and I–, respectively, they can be …

Organic solar cells (OSCs) have again become a hot research topic in recent years. The record power conversion efficiency (PCE) of OSCs has boosted to over 17% in 2020. Apart from the high PCE, the stability of OSCs is also critical for their future
Environmental concerns deriving from fossil fuel dependency are driving an energy transition based on sustainable processes to make fuels and chemicals. Solar hydrogen is the pillar of this new green economy, but the technological readiness level of PV electrolysis and direct photoelectrochemical (PEC) electrolysis are still too low to allow …
The effects of surface treatment with TiCl 4 on the structural and electrochemical properties of a porous titanium oxide (pTiO 2) layer deposited on a fluorine-doped tin oxide (FTO)/glass substrate covered with a dense TiO 2 layer (pTiO 2 /dTiO 2 /FTO/glass) were systematically investigated in order to obtain an optimum pTiO 2 layer for use in CH 3 NH …
In comparison, the working principle of this solar cell is quite different from perovskite solar cells and inorganic p–n junction solar cells. When OPVs are illuminated, a localised and strongly bound exciton (i.e. a bound electron–hole pair) is generated, with the electron in the LUMO (lowest unoccupied molecular orbital) and the hole in the HOMO …

Interfacial defects are considered to be a stumbling block in producing highly efficient perovskite solar cells (PSCs), so a more reasonable design is required for interfacial passivation materials (IPMs) to achieve further improvements in PSC performance. Here, we use fluorine atom (−F) and methoxy (−OCH3) functional groups to …

• Solar → heat, dry clothes, dry food – Solar is still main light source, no need for conversion – Solar is source of biomass, wind, hydro, etc. • Biomass → farm animals → horsepower, food Later, people also did these conversions: • Coal → heat • Hydro → milling flour, running machinery • Wind → pump water
Organic solar cells (OSCs) have been developed for few decades since the preparation of the first photovoltaic device, and the record power conversion efficiency …
