Sensitized Solar Cells

Directions to high efficiency dye-sensitized solar cells (DSCs) are reviewed in terms of light harvesting and charge collection. Three dimensional DSCs characterized by a double dye layer electrode, a floating electrode, and a fiber type electrode are proposed. The potentiality of each structure was discussed by using each model cell. Transparent conductive layerless electrodes were the key structures in these cells. Fabrication processes and fundamental performances are reported. Finally, it is concluded that dyes having high photoconversion efficiency in the near IR and IR regions are essential for realizing these tandem and hybrid cells.

Grating Diffraction

A laterally oriented GaAs p-i-n nanowire solar cell with Ag gratings is proposed and studied via coupled three-dimensional optoelectronic simulations. The results show that the gratings significantly enhance the absorption of nanowire for both TM and TE polarized light due to the combined effect of grating diffraction, excitation of plasmon polaritons, and suppression of carrier recombination. At an optimal grating period, the absorption at 650–800 nm, which is an absorption trough for pure nanowire, is substantially enhanced, raising the conversion efficiency from 8.7% to 14.7%. Moreover, the gratings enhance the weak absorption at long wavelengths and extend the absorption cutoff wavelength for ultrathin nanowires, yielding a remarkable efficiency of 13.3% for the NW with a small diameter of 90 nm, 2.6 times that without gratings. This work may pave the way toward the development of ultrathin high-efficiency nanoscale solar cells.

The three dimensional photovoltaic cell is revolutionary silicon solar cell, design to maximize the conversion of sunlight into electricity. It is like container rather than plane conventional solar cell and has ‘High Efficiency Design to produce 200% of the Power Output of the Conventional Solar Cells’. Three dimensional solar has a special feature on the surface to capture more light in the morning and evening hours, as well as in the winter months when the sun is not directly overhead. Unlike conventional solar cells where electrical contact wires run on the top of the cell, blocking sunlight, three dimensional solar cell use a network of contact wires run below the light collector. Solar Tree is energy generating and harvesting tree, in order to increase efficiency “SPIRALLING PHYLLATAXY” technique is applied. It is way of mounting the three dimensional solar panel (leaf) on the top such a way that maximum sunlight incident on it. It can be applied in street lightening system, industrial power supply etc. It is much better than traditional photovoltaic solar system in area point of viewandalso more efficient. It is perfect solution for future energy needandFibonacci Sequence SolarTree is one of advance solar tree. After using three dimensional solar cell in solar tree, the investment payback period of solar panel systems is40%more than conventional solar panel systems.

AbstractThe photovoltaic performance of perovskite solar cells (PSCs) can be improved by utilizing efficient front contact. However, it has always been a significant challenge for fabricating high-quality, scalable, controllable, and cost-effective front contact. This study proposes a realistic multi-layer front contact design to realize efficient single-junction PSCs and perovskite/perovskite tandem solar cells (TSCs). As a critical part of the front contact, we prepared a highly compact titanium oxide (TiO2) film by industrially viable Spray Pyrolysis Deposition (SPD), which acts as a potential electron transport layer (ETL) for the fabrication of PSCs. Optimization and reproducibility of the TiO2 ETL were discreetly investigated while fabricating a set of planar PSCs. As the front contact has a significant influence on the optoelectronic properties of PSCs, hence, we investigated the optics and electrical effects of PSCs by three-dimensional (3D) finite-difference time-domain (FDTD) and finite element method (FEM) rigorous simulations. The investigation allows us to compare experimental results with the outcome from simulations. Furthermore, an optimized single-junction PSC is designed to enhance the energy conversion efficiency (ECE) by > 30% compared to the planar reference PSC. Finally, the study has been progressed to the realization of all-perovskite TSC that can reach the ECE, exceeding 30%. Detailed guidance for the completion of high-performance PSCs is provided.

Maximum Conversion Efficiency

A horizontally aligned GaAs p–i–n nanowire array solar cell is proposed and studied via coupled three-dimensional optoelectronic simulations. Benefiting from light-concentrating and light-trapping properties, the horizontal nanowire array yields a remarkable efficiency of 10.8% with a radius of 90 nm and a period of 5 radius, more than twice that of its thin-film counterpart with the same thickness. To further enhance the absorption, the nanowire array is placed on a low-refractive-index MgF2 substrate and capsulated in SiO2, which enables multiple reflection and reabsorption of light due to the refractive index difference between air/SiO2 and SiO2/MgF2. The absorption-enhancement structure increases the absorption over a broad wavelength range, resulting in a maximum conversion efficiency of 18%, 3.7 times higher than that of the thin-film counterpart, which is 3 times larger in GaAs material volume. This work may pave the way for the development of ultra-thin high-efficiency solar cells with very low material cost.
