“…Considerable efforts in developing photovoltaics have therefore focused on achieving low cost while increasing their power conversion efficiency (PCE). [1][2][3][4] One recent achievement has been the demonstration of thin-film GaAs solar cells approaching their thermodynamic efficiency limit. [5][6][7][8] However, the cost reduction long promised by the epitaxial lift-off (ELO) process has primarily been limited by the inability to fully recover the original wafer surface quality after each growth, leading to a limited number of times that the substrate can be recycled due to the accumulation of defects and to wafer thinning incurred by chemo-mechanical polishing.…”

Practical solar energy solutions must not only reduce the cost of the module, but also address the substantial balance of system costs. Here, we demonstrate a counter-intuitive approach based on gallium arsenide solar cells that can achieve extremely low-cost solar energy conversion with an estimated cost of only 3% that of conventional gallium arsenide solar cells using an accelerated, non-destructive epitaxial lift-off wafer recycling process along with a lightweight, thermoformed plastic, truncated mini-compound parabolic concentrator that avoids the need for active solar tracking. Using solar cell/concentrator assemblies whose orientations are adjusted only a few times per year, the annual energy harvesting is increased by 2.8 times compared with planar solar cells without solar tracking. These results represent a potentially drastic cost reduction in both the module and the balance of system costs compared with heavy, rigid conventional modules and trackers that are subject to wind loading damage and high installation costs.

The highly efficient polymer solar cells were realized by doping poly(9,9-dioctylfluorenyl-2,7-diyl) (PFO) dots into active layer. The dependence of doping amount on devices performance was investigated and a high efficiency of 7.15% was obtained at an optimal concentration, accounting for a 22.4% enhancement. The incorporation of PFO dots (Pdots) is conducted to the improvement of Jsc and fill factor mainly due to the enhancement of light absorption and charge transport property. Pdots blended in active layer provides an interface for charge transfer and enables the formation of percolation pathways for electron transport. The introduction of Pdots was proven an effective way to improve optical and electrical properties of solar cells.

“…Plasmonic is one of the most effective routes for light trapping and absorption enhancement [42][43][44]. A domain of different plasmonic structures such as metallic nanoparticles [45][46][47], gratings [48][49][50], antennas [51,52] and others [53,54] have been used to improve the performance of solar cells. Graphene when compared to conventional plasmonic materials such as gold and silver has less losses and is very promising for light trapping in optoelectronic devices [55].…”

The worldwide consumption of energy has increased every year by several percentages in the last decades. Nowadays, a large amount of energy is produced by fossil fuels and to a certain extent by nuclear energy. However, these resources are limited and their use has a serious environmental impact. Solar light is the most important source of regenerative energy and represents an inexhaustible energy source. Owing to this fact the attention has been drawn during the last few years towards Solar cells. Moreover, to overcome barriers such as effective cost efficiency and commercial feasibility, methods of energy generations have turned to Organic Photovoltaics devices. The advantages being: generation of cost effective devices, use of renewable sources of energy and easy flexibility. In recent years rapid development in design has led to progressive PCE of organic solar cell from 3% to almost 9-10%. To improve the efficiency of organic solar cells it is, therefore, crucial to understand what limits the cell's performance and efficiency. The scattering from the metal nanoparticles is a way of increasing the light absorption and the efficiency in organic solar cells. This review discusses the recent significant technological developments that were presented in the literature with the basic mechanisms at work, which will help improve the organic photovoltaic performance and provide an outlook to future prospects in this area.
