Improvement of short circuit current of mono crystalline silicon solar cells
In this report we present series of experiments during which the short circuit current of mono crystalline silicon solar cell was improved step by step so as a consequence the efficiency was increased. At first, the front contact of solar cell was optimized to reduce the shadow loss and the series r[r]
