Solar cell technology exhibits many advantages compared to traditional fuel-based energy sources, such as widely available free energy source, zero emission, no noise, safe, and versatility. It also has certain disadvantages: Energy source is thin and diffussive, lack of economic energy storage system, and high installation cost. With the technology improvement and government incentives, solar photovoltaic (PV) cells become viable in more applications, including space and terrestrial power sources for space station, satellite, building, car, and various consumer electronics. It has been producing broad impacts on human life and changing the engineering practice in the past decade.The solar power generation market has been experiencing rapid and vast growth. With the worldwide revolution toward sustainable development, alternative energy has become a top priority. Solar power is at the forefront of alternative energy sources because of its immense potential and availability. Currently, there are three generations of solar cell types: bulk silicon, thin-film, and organic. Bulk silicon PV cells have been invented for decades and is the most common material for solar panels; thin-film cells are a relatively new technology and they are entering the market with success; and finally, organic solar cells are still in the research phase and some challenging problems in efficiency and durability are to be solved before becoming commercially viable. Overall, nine types of solar cells were reviewed:

“…Firstly, solar energy as a green and cost-effective renewable energy has been utilized in recent years. There is an energy harvesting system that not only harvests both solar and thermal energies with a solar tracking system, but also converts the thermal energy to electrical energy by the TEG, thus the proposed system has increased the conversion efficiency to 38.65% [2][3][4][5]. Secondly, there is about 40-70% thermal energy loss through the exhaust system in the vehicle with a gasoline engine.…”

Abstract:The development of the thermoelectric (TE) power generation is rapid, and the applications have extensively been studied. The principle is based on the Seebeck effect, in which the temperature difference between hot and cold sides of the TE material converts to electrical energy. In this paper, a design is proposed to convert the thermal energy between indoor and outdoor of a board to electrical energy by the thermoelectric generator (TEG). Furthermore, the electrical energy generated is charged to supercapacitors as a battery or a power supply to the loads (e.g., lights) of the house. Besides the experimental work, a thermal model and an electrical model of the TEG have been proposed. To study the power generation performance in terms of materials, the simulation of the conversion efficiency of the TE board using materials with different thermal conductance have also been conducted. It was found that, using graphene as the thermally conductive material, the conversion efficiency was enhanced by 1.6% and 1.7%, when the temperature difference was 15 • C and 40 • C, respectively.

Conventional boost-full-bridge and boost-hybrid-bridge two-stage inverters are widely applied in order to adapt to the wide dc input voltage range of photovoltaic arrays. However, the efficiency of the conventional topology is not fully optimized because additional switching losses are generated in the voltage conversion so that the input voltage rises and then falls. Moreover, the electrolytic capacitors in a dc-link lead to a larger volume combined with increases in both weight and cost. This paper proposes a higher efficiency inverter with time-sharing synchronous modulation. The energy transmission paths, wheeling branches and switching losses for the high-frequency switches are optimized so that the overall efficiency is greatly improved. In this paper, a contrastive analysis of the component losses for the conventional and proposed inverter topologies is carried out in MATLAB. Finally, the high-efficiency under different switching frequencies and different input voltages is verified by a 3 kW prototype.
