Full spectrum boosts solar cell power
A solar cell is a device that converts sunlight into electrical power. This conversion process, however, is typically not very efficient: a conventional silicon solar cell commercially available today converts only 15-20 percent of the energy of the sunlight to electricity and a large fraction (80-85 percent) is lost as heat.
Blue and green light are converted to electricity with an efficiency less than 50 percent, while infrared light is not absorbed by a silicon solar cell at all. The highest record efficiency ever realized by a silicon solar cell is only 27 percent.
Light that is not converted in the solar cell leads to thermodynamic disorder known as entropy and therefore a reduced cell voltage. As a result, the maximum achievable efficiency is limited to 34 percent, the so-called Shockley-Queisser limit.
Also, the incomplete trapping of light inside the solar cell and defects in the solar cell material’s crystal structure cause a loss in efficiency.

where could i buy a cheap and low cost solar panel regulator?
it is just for a simple project, but i am looking for a cheap, low cost, around one to two volts solar panel regulator.
could y'all please help?
Solar cells shouldn't need a voltage regulator for simple projects like driving motors or powering CMOS electronic circuits. I would need to know a little more on your goals for the project to help.
