They claim the panels can dynamically self-adjust their optical transmittance according to sunlight intensity. The mini panels offer power output In the W-type architecture, the inter-distance between cells can be smaller due to the absence of vertical interconnects. In the cells, the scientists replaced the commonly used organic dyes with photochromic dyes based on diphenyl-naphthopyran. These dyes are uncolored in the dark and can become colorful when exposed to light.

This fully transparent solar cell could make every window and screen a power source - ExtremeTech
A new generation of see-through solar cell technology could soon be used to harvest the massive energy potential of building and car windows, cell phones as well as other objects with a transparent surface. Scientists at Michigan State University detailed in a paper in the journal Nature Energy how highly transparent solar applications could "nearly meet U. Lunt and his MSU colleagues have previously pioneered solar technology that collects energy from invisible wavelengths of light so that it doesn't disrupt the view when placed over a window. The system uses materials to pick up ultraviolet and near infrared wavelengths, which are guided to the edge of the surface they are on for it to be converted into electricity by thin strips of photovoltaic solar cells. Ultra-thin, transparent solar panels could potentially be retrofitted onto skyscrapers and smartphones, meaning windows and screens would not need to be replaced in order to generate electricity from buildings or electronic devices. Compared to traditional solar cells , the transparent technology still has some catching up to do. Rooftop solar panels typically have an efficiency of between 15 and 18 percent, whereas the see-through solar cells record efficiencies of around 5 percent.

Using semi-transparent organic solar cells for their research wok on energy harvesting in greenhouses North Carolina State University researchers wanted to find out how these cells can affect greenhouse crops. They created semi-transparent organic solar cells ST-OSC for their research work that they believe enable simultaneous plant cultivation and electricity generation thereby reducing the energy demand of a greenhouse. For their experiment, researchers grew crops of red leaf lettuce in greenhouse chambers for 30 days, from seed to full maturity, with all other factors as constant, except for light, for the lettuces were divided into 4 experimental groups.
Belgian researchers are testing agrivoltaic power generation in a pear orchard. A Belgium-based energy research team led by the KU Leuven has developed an agrivoltaic pilot project in Bierbeek, Flanders. They specifically designed the system for orchard crops. The pilot plant is of the first outcome of a technology transfer project funded by the Flemish government and co-funded by 20 unspecified companies. It is designed to demonstrate the feasibility of agrivoltaics in Belgium.
