The Silicon PV Value Chain

Suniva is focused on the design and manufacturing of high efficiency silicon based photovoltaic cells marketed as the ARTisun product series.  ARTisun solar cells are two steps upstream in the value chain from the end user or consumer of solar power.  However, since our ARTisun cells are the "brains" inside the solar modules or panels which

our customers manufacture using our cells, Suniva has a great impact on the downstream

products.

Boosting solar cell efficiency can have a dramatic impact on the entire value chain, from requiring less starting raw material (polysilicon) to reducing the module area required for systems.  A higher efficiency cell will mean the same amount of silicon will deliver more power per module or conversely, the same power output can be achieved with fewer wafers, meaning less ingot is required, and ultimately, less raw polysilicon is required for the same power output. 

Higher efficiency cells will also mean modules will produce more power per unit or conversely, the same power can be generated with smaller area modules.  This enhances solar applications potential where limited rooftop space previously restricted or precluded it. Requiring a smaller module footprint area has the additional benefits of reducing support structure and installation costs.

Suniva focuses exclusively on its ARTisun series high-efficiency silicon solar cell production and sells to module producers.

Suniva's plan is to increase cell efficiency to 20+% so that fewer cells are needed to build modules of comparable output.  Shrinking the size of modules has the effect of reducing the cost of module materials, module support structure and installation time.  By also reducing cell thickness from 250 µm (microns) to about 150 µm while maintaining cell efficiency, raw material costs, the largest single component by far in the cost equation, can be cut dramatically.
