ABSTRACT
Solar insolation is the most abundant natural energy source for Earth. Solar radiation can be transformed into various energy forms such as heat and chemical energy (e.g., via photosynthesis). Natural energy sources will be depleted in the near future due to their rapid and uncontrolled consumption. In this regard, solar energy may play a very important role as an alternative energy source. The Sun provides about 120,000 TW of energy toward Earth’s surface. This amount is about 6000 times the present rate of the world’s energy consumption. It is a challenge to use solar energy as environmentally friendly chemical fuels and photoconversion devices are necessary to
