Radio Shack Silicon Solar Cell 276-0124 User's Manual
Contents
1. which is Solar irradiance of 1 000 W M2 cell temperature of 25 C How does temp rature affect the power of the cell Remember it is light not heat that produces the power Cold temperatures have little effect on power howaver very hot conditions i e 100 F will cause the voltage to drop lower Where are the negative and positive connections on the cell Tha front of the cell blue dazk color is negative solder to the silver colored bar running across the front edge of the cell The beck of the cell is positive moldear anywhere on the back Are there any tips on woldering the cells Reconnended soldering tip temperature is 650 700 F Use thin wire a single copper strand out of speaker wire works well Put flux on cel first put solder on tip place wire on cell drag tip across Do not held soldering tip down on cell in one spot a3 this may lift the coating off the cell Are there any charts dapicting solar cell response to color or frequency wavelengths Yes xefer to the following charts Charts also show series and parallel connection of cells Silicon Solar Cell 276 0124 Hints and Tips Q Which are the front and back of this cell in order to solder leads A The front is blue dark and is negative Solder the lead to the silver bar on the front edge The back is positive The lead can be soldered to any place on the back Soldering Tips Put flux on cell first Put the solder on tip Place wire on cell Drag tip2.
