Hyper Concentrated Photo Voltaics ((H)CPV)

(H)CPV technology differs from conventional photovoltaic systems, in that the CPV modules use different solar cells and include a glass based curved system which focuses light energy in a more concentrated manner, hence harvesting more energy and is environmentally friendly with above 90% recyclable material. The efficiency of the cells used provides benefits relating to capacity per module, cost effectiveness, reduced spatial requirements and improved climate change benefit, with a shorter energy payback period. With fewer footprints it can be better utilized in rural setting such as pumping water from tube wells. Boeing along with aid from DAE has spent millions of dollar researching and developing highest CPV panel efficiency.

(H)CPV technology is capable of outperforming any other technology currently available, not only in efficiency but cost as well as performance. Our technology will help achieve its energy goals keeping the levellized cost of energy (LCOE) much lower than conventional PV panels.

(H)CPV systems can greatly reduce the installation space using a dual-axis tracker. For example, a 6.3KW system on a dual-axis tracker covers area about 5 square meters, but the fixed solar power generation system with the same capacity needs about 40 square meters. This proves to reduce land area about 35 square meters, (not including the reducing area by increasing generation capacity).

Concentrated Solar Power (CSP)

Concentrated solar power (also called concentrating solar power, concentrated solar thermal, and CSP) systems use mirrors or lenses to concentrate a large area of sunlight, or solar thermal energy, onto a small area. Electrical power is produced when the concentrated light is converted to heat, which drives a heat engine (usually a steam turbine) connected to an electrical power generator or powers a thermo chemical reaction.


Thin Film (TF)

Thin-film solar cell (TFSC), also called a thin-film photovoltaic cell (TFPV), is a second generation solar cell that is made by depositing one or more thin layers, or thin film (TF) of photovoltaic material on a substrate, such as glass, plastic or metal. Thin-film solar cells are commercially used in several technologies, including cadmium telluride (CdTe), copper indium gallium diselenide (CIGS), and amorphous and other thin-film silicon (a-Si, TF-Si).

Film thickness varies from a few nanometers (nm) to tens of micrometers (µm), much thinner than thin-film's rival technology, the conventional, first-generation crystalline silicon solar cell (c-Si) that uses silicon wafers of up to 200 µm. This allows thin film cells to be flexible, resulting in lower weight, less drag and limited resistance to foot traffic. It is used in building integrated photo voltaics and as semi-transparent, photovoltaic glazing material that can be laminated onto windows. Other commercial applications use rigid thin film solar panels, sandwiched between to panes of glass, used in some of the world's largest photovoltaic power stations.

Thin-film has always been cheaper but less efficient than conventional c-Si technology. However, they significantly improved over the years, and lab cell efficiency for CdTe and CIGS reached almost 20 percent and are on par with polysilicon, the dominant material, currently used in most PV installations. Despite these facts, market-share of thin-film never reached more than 20 percent in the last two decades and has been declining in recent years to about 9 percent of worldwide photovoltaic production in 2013.

Other thin-film technologies, that are still in an early stage of ongoing research or with limited commercial availability, are often classified as emerging or third generation photovoltaic cells and include, organic, dye-sensitized, and polymer solar cells, as well as quantum dot, copper zinc tin sulfide, and perovskite solar cells

Solar Photovoltaics (PV)

Photovoltaics (PV) is a method of generating electrical power by converting sunlight into direct current electricity using semiconducting materials that exhibit the photovoltaic effect. A photovoltaic system employs solar panels composed of a number of solar cells to supply usable solar power. Power generation from solar PV has long been seen as a clean sustainable energy technology which draws upon the planet’s most plentiful and widely distributed renewable energy source – the sun. The direct conversion of sunlight to electricity occurs without any moving parts or environmental emissions during operation. It is well proven, as photovoltaic systems have now been used for fifty years in specialized applications, and grid-connected PV systems have been in use for over twenty years.

Two types of solar panels are used commonly, namely Mono-Crystalline and Poly-Crystalline.
