工程学论文代写 New Development In Solar Cell
Flexible Solar Cell
. Solar technology has reached its most convenient, lightweight form: the newly-engineered flexible solar panel. Silicon Solar is the proud carrier of over 50 modules of flexible solar panels, offered in a variety of sizes.
Through recent developments, Silicon Solar has provided ways of listing thin, light weight, flexible solar panels allowing for multiple applications to now be solar accessible that never were before. It is possible to deposit thin layers of silicon onto flexible substrates, such as polyethylene terephthalate (PET). The silicon is able to bend along with the flexible PET substrate without compromising structure because the silicon layers are only micrometers thick. They are capable of being flexible because of the production process used: thin film deposition.
Tandom Solar Cell
A 25cm square prototype Tandem Cell in front
of the laboratory artificial sunlight source
lThe Tandem Cell consists of two photo-catalytic cells in series: the front cell absorbs the high energy ultraviolet and blue light in sunlight, using nano-crystalline metal oxide thin films to generate electron-hole pairs. The longer wavelength light in the green to red region passes through the front cell and is absorbed in a Graetzel Cell producing electrical potential under nearly all light conditions The two cells are connected electrically and together provide the potential required to split the water molecules in the electrolyte. The Cell is fabricated from widely-available and cheap materials. We are developing processes to obtain high efficiency films in a usable form. The metal oxides are expected to be the limiting feature of Tandem Cellâ„¢ efficiency, but we also need to optimise all other aspects, including the counter-electrodes, the electrolytes and the mechanical design to maximise light gathering and hydrogen collection. The most expensive component of the Cells is currently the special glass, on which the nano-crystalline films are deposited.
Nano Solar Cell
They have a conversion efficiency of around 6.5%. However, they have a theoretical efficiency of 19.5%, so it’ll increase as the technology matures. even at 6.5% efficiency, they are still very cost effective. The industry’s first solar electricity panel specifically designed and developed for utility-scale solar power system deployment. Through its innovative product design, the panel significantly reduces the “balance-of-system penalty” that medium-efficient thin panels have conventionally carried relative to higher-efficiency (yet far more expensive) silicon panels.
Polymer Solar Cell
Polymer solar cellsÂ are a type of flexible solar cell. They can come in many forms including:Â organic solar cellÂ (also called plastic solar cell), orÂ organic chemistryÂ photovoltaicÂ cell that produceÂ electricityÂ fromÂ sunlightÂ usingÂ polymers. There are also other types of more stable thin-film semiconductors that can be deposited on different types of polymers to create solar cells. This technology is relatively new, being actively researched by universities, national laboratories and several companies around the world.
Currently, commercial solar cells are made from aÂ refined, highly purified siliconÂ crystal, similar to the material used in the manufacture ofÂ integrated circuitsÂ and computer chips (wafer silicon). The high cost of these silicon solar cells, and their complex production process has generated interest in developing alternative photovoltaic technologies.
Hybrid Solar Cell
Hybrid solar cellsÂ combine advantages of bothÂ organicÂ and inorganicÂ semiconductors. Hybrid photovoltaics have organic materials that consist ofÂ conjugated polymersÂ that absorb light as the donor and transportÂ holes.Â Inorganic materials in hybrid cell are used as the acceptor andÂ electronÂ transporter in the structure. The hybrid photovoltaic devices have a significant potential for not only low-cost byroll-to-rollÂ processing but also scalable solar power conversion.
