laptop Batteries: Roma exhibition indoor use dye-sensitized solar cells

Roma exhibition indoor use dye-sensitized solar cells

Roma developed a dedicated indoor use dye-sensitized solar cells, and in "CEATEC JAPAN 2009" were on display. Compared with silicon solar cells, low-light environments in indoor dye-sensitized solar cell conversion efficiency high, Roma focus on this characteristic, developed for clocks, indoor sensor networks, mobile phones, wireless mouse and headphones such as solar cells.

The development of dye-sensitized solar cells by optimizing the indoor low-light environments such as pigments, and electrode design, 3330lx under fluorescent light to electricity conversion efficiency 20.25%. Roma in the group with OKI Semiconductor's technology was developed. The goal is to expand the future of dye-sensitized solar cells for indoor use, while the development of evaluation with the test products.

In addition, the Roma consider the dye-sensitized solar cells generate electricity as both decorative elements used, but also exhibited a fan shape, and can display a variety of colors and tones.

TDK reference display may be manufactured by roll to roll thin-film amorphous silicon solar cells

TDK in "CEATEC JAPAN 2009" can be exhibited on the reference volume on the volumes stop production of thin film technology of amorphous silicon solar cells. The battery is flexible products, in addition to the use of the surface can be set in addition, its thin, lightweight features make the impact resistance is relatively high. Idea for mobile phones and other electronic products and home / outdoor power generation and other purposes.

TDK production had been a single chip (Single Wafer) production of thin film amorphous silicon solar cells, in the intended use of smaller clocks to achieve the commercial. Roll the way of the established production technology, the goal is mass production of tens of m long-size products. Uniformity through the development of a large area of the formation of amorphous silicon solar cell technology, the volume on the volumes produced.

The demonstration of the test products, the module width is about 180mm, length of about 20m. Thickness of the laminate before processing 0.2mm, laminated processing after 0.4 ~ 0.5mm. Cell conversion efficiency is about 10%, module conversion efficiency is about 7%. Indoor environment in low light to high intensity outdoor environment widely used. The company hope that the cell conversion efficiency increased to 16 to 17%.
