Solar cell efficiency may get a bump from bumps. New research suggests that building tiny domes into the surface of organic solar cells could boost their efficiency by up to two-thirds, while capturing light from a wider angle.
Solar cells are usually flat, which maximizes how much of the surface is exposed to sunlight at any given time. This design works best when the Sun is within a certain angle, so the panels are usually tilted between 15 and 40 degrees to get the most out of the day.
Scientists have toyed with other shapes for the surface, including embedding spherical nanoshells of silica which trap and circulate sunlight to allow the device to capture more energy from it. For the new study, scientists at Abdullah Gül University in Türkiye ran complex simulations of how dome-shaped bumps might boost organic solar surfaces.
The team studied photovoltaic cells made with an organic polymer called P3HT:ICBA as the active layer, above a layer of aluminum and a substrate of PMMA, capped off with a transparent protective layer of indium tin oxide (ITO). This sandwich structure was kept through the whole dome, or "hemispherical shell" as the team calls it.

Compared to flat surfaces, solar cells dotted with bumps showed 36% and 66% improvements in light absorption, depending on the polarization of the light. Those bumps also allowed light to enter from a wider range of directions than a flat surface, providing an angular coverage of up to 82 degrees.

I can build a "complex simulation" that shows whatever you want. Wake me when they have an actual prototype that does what they claim. And more importantly, when it can be determined such a product would be profitable to manufacture.

Imho this is not really rocket surgery. If you can focus the light to the solar cell, it will transform more energy. I mean i was never that good at physics and i have a specific memory about the reflection/lense crap in physic labs, that i did not master it, but it should work. I do concur in that a prototype would be the way to go before announcing results, and it shouldn't be too hard to make one in this case. Someone with more knowledge can disprove what i just said, but so be it.
