The most important issue is that you must use good absorbing material to fabricate the solar cells. Perovskite solar cells are potentially the most promising solar power technology for researchers right now. First appearing in 2009 with an efficiency of just 3.8 percent, engineers around the world have been developing new ways to increase its energy conversion efficiency.
The study team noted that a calibrated mix of solar cell materials would be ideal for energy absorption because different materials absorb different wavelengths for solar energy. For instance, methylammonium lead tri-halide perovskite and silicon solar cells are a complementary pair. With the perovskite as a top layer, it can collect the short wavelength photons while the bottom silicon layer absorbs long wavelength photons.
Material selection !! For photons to travel deeper in the material (for absorption) say silicon around 1100nm with doping may be more for a wafer of certain thickness !! They are characterized and certain faces . Changes for organic material , search for depth of penetration of light in materials .

For current solar absorption materials, they operate at low temperatures and need to be repaired and tested almost every year when working at high temperatures. A team of US researchers has created a new material to absorb solar energy. The new material is characterized by having a multi-band surface, made using multi-sized particles ranging from nanometer to micrometer. These multi-band structures have the ability to capture and absorb light, which increases the efficiency of the material when working at high temperatures.
I think surface area also plays an important role. If previous cells are cylinderical in shape try to give spherical shape. No more technical detail known to me. Your work is very Nobel best of luck Dr.Maytham
Absorption is depending on material band gap.Moreover, dye adsorption is depending on shape dependent. I saw some papers, they stated that dye adsorption is more for spherical shape particles compared to rod and flakes, etc. Because in the spherical particles, dye adsorp in the entire region but in flake and rods it adsorp only blunt corners.
From the Beer_Lambert law concentration of adsorption is more naturally absorption also more.
