THE INTENT
Many different applications are found within the realm of photovoltaic technology.
As well, there are many different types of display technologies which are useful in their own ways, however, these two ideas have rarely been found in union. This blog is an introduction to developing a marriage of photovoltaic ink and OLED video technology within a single glazing unit. This concept has many useful places in our daily lives, but this is primarily an architectural inquiry.

starting from square one, the model was redeveloped. this way a definite curtain is exposed, and the glazing can be utilized.
the building's mainframe system can control all of the OLED displays so that images can move, and different screens can work in conjunction with eachother.

during the day, a building facade could absorb radiant energy using photovoltaic OLED panels.
at night, these panels could become a display; these glass walls could become completely opaque, show video signage. the possibilities are endless.
the polymer and anode layers are microscopic and can be applied using the same techniques found in laser printing. the human hair is approximately 200x the size. photovoltaic inks would be applied to the glass substrate, which is the same place that a silicon film would be applied to redirect radiant energy toward the edges. a frame would be necessary to conceal the mechanisms used to redirect the energy from the panel.
PHOTOVOLTAICS
Photovoltaics (or PV) is the field of technology and research related to the application of solar cells for energy by converting solar energy directly into electricity.[1] Due to the growing demand for renewable energy sources, the manufacture of solar cells and photovoltaic arrays has advanced dramatically in recent years.[2][3][4]
Photovoltaic production has been doubling every 2 years, increasing by an average of 48 percent each year since 2002, making it the world’s fastest-growing energy technology, and then increased by 110% in 2008.[5] At the end of 2008, the cumulative global PV installations reached 15,200 megawatts.[6][7] Roughly 90% of this generating capacity consists of grid-tied electrical systems. Such installations may be ground-mounted (and sometimes integrated with farming and grazing) [8] or built into the roof or walls of a building, known as Building Integrated Photovoltaics or BIPV for short.[9]

There are many ways that photovoltaics are utilized, and furthermore, the capabilities of each type of installation usually is efficient in its own sort. One very interesting development is one which has progressed rapidly in the last year. Recently, scientists at MIT improved the field of photovoltaics by integrating nanotechnology to invent a ink which can be applied to the out rim of flat glass panels. The radiant energy is reflected toward the edges of the glazing using a transparent silicon film on the glass. This silicon is similar to the same structural component in OLED screens.

The cost of photovoltaic power can be reduced with organic solar concentrators. These are planar waveguides with a thin-film organic coating on the face and inorganic solar cells attached to the edges. Light is absorbed by the coating and reemitted into waveguide modes for collection by the solar cells. We report single- and tandem-waveguide organic solar concentrators with quantum efficiencies exceeding 50% and projected power conversion efficiencies as high as 6.8%. The exploitation of near-field energy transfer, solid-state solvation, and phosphorescence enables 10-fold increases in the power obtained from photovoltaic cells, without the need for solar tracking.

OLED
Such systems can be used in television screens, computer monitors, small, portable system screens such as cell phones and PDAs, advertising, information and indication. OLEDs can also be used in light sources for general space illumination, and large-area light-emitting elements. OLEDs typically emit less light per area than inorganic solid-state based LEDs which are usually designed for use as point-light sources.

Transparent OLEDs have only transparent components (substrate, cathode and anode) and, when turned off, are up to 85 percent as transparent as their substrate. When a transparent OLED display is turned on, it allows light to pass in both directions. A transparent OLED display can be either active- or passive-matrix. This technology can be used for heads-up displays.
