Electrolysis And Storage Of Batteries — Part 1 MCQs with Explanations

A typical output voltage of a solar cell, which is also known as the open-circuit voltage (Voc), can vary depending on the type of solar cell and its specific characteristics. However, a commonly encountered voltage for solar cells is around 0.26 V. This voltage represents the electrical potential generated by the solar cell when it is exposed to sunlight and is not connected to any external load. It's important to note that the voltage of a solar cell can vary based on factors like the type of materials used, the amount of sunlight, and the design of the cell. The other options do not typically represent the output voltage of a standard solar cell: Option A: 0.1 V is lower than the usual output voltage of a solar cell. Option C: 1.1 V is higher than what is typically found in standard solar cells. Option D: 2 V is also higher than the typical voltage output of most solar cells. So, the correct answer is Option B: 0.26 V , which aligns with a common output voltage for solar cells
