Solar energy is freely available and in abundant amount. The photon energy from the sun is absorbed by the solar panels and converted into electricity. But the low efficiency of the conversion of light energy into electricity limits the wide use of solar cells. It is well known that carbon materials are extensively used in solar thermal transportation application because of

Solar Cell Efficiency Explained. Cell efficiency is determined by the cell structure and type of substrate used, which is generally either P-type or N-type silicon, with N-type cells being the most efficient. Cell efficiency is calculated by what is known as the fill factor (FF), which is the maximum conversion efficiency of a PV cell at the optimum operating voltage and
Navitas estimates that the market for GaN chips in residential solar applications could reach $1 billion a year and that GaN power ICs have the potential to lower inverter costs by as much as 25% while delivering energy savings of 40% or more.

Linear Technology has released a wide range of ultra-low-power boost converter modules for harvesting energy from piezoelectric and photovoltaic sources to thermoelectric generators (TEGs). They include step-up DC/DC converters such as LTC3108 /
Solar energy received by the earth is many times more than what we need. Limitations are due to inadequacies in the conversion devices. For example, the amount of solar energy that reaches the earth is 1.75 × 10 17 W,
It is reported that the energy generated by forest biomass can support 15.4% of the total human energy consumption (Welfle et al., 2014).During the period 2004–2015, the whole power generation from forest biomass stood at around one million kW/yr, contributing to the elimination of forest residues and achieving ecological-zero carbon dioxide (CO 2) emissions
Energy Conversion Efficiency refers to the ratio between the maximum electrical power that can be produced by a solar cell and the power of the incident radiation it receives. It indicates how effectively a solar cell can convert sunlight into usable electricity.
