Blocking Diode and Bypass Diodes in a Solar Panel Junction Box
A single photovoltaic cell generates about 0.58 DC volts at 25°C. In case of open circuit, typically the value of V OC is 0.5 – 0.6V while the power of a single photovoltaic cell is 1 to 1.5 W in case of open circuit. So a single photostatic cell of 1.5W with 0.5V will produce 3A current as I = P /V (1.5W / 0.5V = 3 Amperes).

Thin film GaAs solar cell
The Shockley-Queisser limit, when combined with the AM1.5G solar spectrum, sets the maximum efficiency for a single junction photovoltaic cell at 33.7% with and ideal band gap of 1.34eV, which is very close to GaAs (with a maximum theoretical efficiency of 32.8%) [Araujo90].
Design and Optimization of a Self-Protected Thin Film c-Si Solar Cell ...
Current mismatch due to solar cell failure or partial shading of solar panels may cause a reverse biasing of solar cells inside a photovoltaic (PV) module. The reverse-biased cells consume power instead of generating it, resulting in hot spots. To protect the solar cell against the reverse current, we introduce a novel design of a self-protected thin-film crystalline …
