Silicon germanium solar cells have widely been explored in recent years due to the property of germanium material that is capable to absorb light in low energy (IR range). However, the lattice mismatch between the silicon and germanium materials may lead to misfit dislocation defect on the solar cell. The defect can be reduced by arranging the silicon and germanium materials in superlattice (multilayer)...
In this research, an optimization of monthly tilt angle for solar panels for five main sites in Malaysia is conducted. The optimization method is based on the Liu and Jordan model for solar energy incident on a tilt surface. As a result, applying the monthly optimum tilt angle, increases the collected yields of the PV module/array in Kuala Lumpur, Johor Bharu, Ipoh, Kuching and Alor Setar by 5.03%,...
Pico hydro is a green energy that consumes a small streams to generate electricity without depends on any sources of non-renewable energy. This green scheme offer a cheap, efficient, reliable and cost effective of alternative energy and hence, there is no need to worries about the fuel source, capital cost, pollution and life expectancy. Even though the power generated is less than 5kW, but the benefit...
