While both transparent and translucent solar cells allow for light transmission, translucent cells have the distinct advantage of diffusing and scattering incoming light within the cells, softening the illumination, and providing privacy.

The photoactive layer of these visibly transparent polymer solar cells harvests solar energy from the near-infrared region while being less sensitive to visible photons. The top transparent electrode employs a highly transparent silver nanowire–metal oxide composite conducting film, which is coated through mild solution processes.
At the front of the solar cells, these TCO layers act as the optically transparent electrode that allows photons into the solar cell and transports the photo-generated electrons to the external device terminals. Therefore, high lateral conductivity and low UV-IR absorption are crucial requirements of the front TCO of any solar cell device.
Transparent solar cells (TSCs) are promising energy-harvesting devices that can be applied to the windows of buildings, thereby eliminating the space limitation of existing solar panels. In addition, TSCs do not decrease the aesthetics of the target application.
The optical transmittance, reflectance, and haze ratio of the transparent c -Si solar cells were measured in the wavelength range of 300–1,100 nm using a UV-vis/NIR spectrophotometer (Cary 5000, Agilent) equipped with a 110 mm integrating sphere to account for the total light (diffuse + specular) reflected from the devices.
But in the visible region, absorption drops off, approaching zero. That critically placed gap makes the MIT solar cell transparent to the human eye—but it also means that the cell does not capture all the incident energy. “We do let the visible photons [light particles] pass through, allowing them to efficiently light the room.
In contrast, the transparent cell (bottom) absorbs well in the near-infrared and the ultraviolet parts of the spectrum—both above and below the visible range. But in the visible region, absorption drops off, approaching zero.
