Reliability Enhancement of Solar Panels Based on the Photocurrent Equality

The world currently faces the climate change, as a serious environmental issue, which is likely to have major negative subsequence. To encounter this problem, it is supposed that renewable energy systems (RESs) should be one of the top priorities to ensure proper actions are being taken to tackle the global warming problems. As a particular case, solar cells are increasingly being installed around the world either in large and small scales to help environment and eventually reduce the greenhouse gas emission. This all means that design of the solar cells needs to be improved in order to enhance their performance and this improvement cannot be done without considering safety and reliability of the solar cells. In this talk, a solar cell with a photocurrent and a diode is considered to be investigated in terms of reliability analysis issues. For this purpose, the photocurrent equality is used to introduce a new system performance function for the solar cells. This performance function is then employed to set up a reliability analysis problem that aims at investigating the solar cell reliability. A numerical experiment is also provided to represent how this model can be used to enhance the solar cell design. Two of the most stable and efficient existing reliability analysis methods are selected to solve the proposed problems.
