“…A preferable part of the installation is the vehicle roof. Because of space limitation for passenger cars, development high-efficiency solar cell modules with efficiencies of more than 30% is very important as shown in Figure 21 [46,47]. High-Efficiency GaAs-Based Solar Cells DOI: http://dx.doi.org /10.5772/intechopen.94365 In addition to high-efficiency, cost reduction of solar cell modules is necessary.…”

The III-V compound solar cells represented by GaAs solar cells have contributed as space and concentrator solar cells and are important as sub-cells for multi-junction solar cells. This chapter reviews progress in III-V compound single-junction solar cells such as GaAs, InP, AlGaAs and InGaP cells. Especially, GaAs solar cells have shown 29.1% under 1-sun, highest ever reported for single-junction solar cells. In addition, analytical results for non-radiative recombination and resistance losses in III-V compound solar cells are shown by considering fundamentals for major losses in III-V compound materials and solar cells. Because the limiting efficiency of single-junction solar cells is 30-32%, multi-junction junction solar cells have been developed and InGaP/GaAs based 3-junction solar cells are widely used in space. Recently, highest efficiencies of 39.1% under 1-sun and 47.2% under concentration have been demonstrated with 6-junction solar cells. This chapter also reviews progress in III-V compound multi-junction solar cells and key issues for realizing high-efficiency multi-junction cells.

“…In order to get 2 kWh of energy per day, a module of 800 W must be installed in the vehicle. The area for installing the 800 W module is 3.6 m 2 , which is more than 2.5 m 2 combined with the roof and hood, so it needs to be installed on the side of the vehicle [11]. If you include the side of the vehicle, it is 4.5 m 2 .…”

Twenty-three percent of carbon emissions come from fossil fuels used in transportation. Electric vehicles are suggested as alternatives to fossil-fueled vehicles. Cars having vehicle integrated photovoltaics (VIPV) on the roof have recently been launched, aiming to increase fuel efficiency and increase maximum mileage by supplying electricity to the vehicle when needed. VIPV needs to be light in terms of efficiency. The use of polymeric materials, made of low-iron tempered glass on the front that contributes significantly to the module’s weight, is required instead. The use of a sandwich structure with polymer material achieves nine times stiffer rigidity than an aluminum sheet of the same weight. It can be used with a weight that is half that of glass through the lightweight and light-transmitting polymer material on the front side. The concentrator photovoltaic module structure is used to compensate for various angles of incidence on a moving car, and it is advantageous because it is easy to apply and has a low weight owing to its excellent flexibility. It is possible to reduce the weight from 20 kg to less than 10 kg by limiting the use of glass.

“…Development of the PV(photovoltaics)-powered vehicle [1] [2] [3] [4] [5] is desirable and very important in order to create a new clean energy society. Because the PV-powered vehicles have great potential of reducing CO 2 emission from 59 g-CO 2 e/km in the case of EV (battery-powered Electric Vehicle) to 15 g-CO 2 e/km [4] [5]. According to the NEDO's Interim Report "PV-Powered Vehicle Strategy Committee" [2], a new broader PV market with more than 10 GW and 50 GW in 2030 and 2050, respectively, are expected to be established when PV-powered vehicles are developed.…”

“…This paper presents the importance of developing PV-powered vehicles from point views of reduction in CO 2 emission and total cost reduction. Although developing high-efficiency solar cell modules has been shown to be very effective [4] [5] in order to develop attractive PV-powered vehicles, quantitative analysis for the impact of high-efficiency solar cell modules upon an increase in driving distance, reduction in CO 2 emission, and total cost reduction are necessary. This paper shows the quantitative analysis for the impact of solar cell module efficiency upon extension of driving distance in Section 2 and Section 5, impact for reduction in CO 2 emission in Section 3, impact for charging cost reduction and reducing storage capacity of PV-powered electric vehicles in Section 4.…”

The development of photovoltaics (PV)-powered vehicles are expected to contribute to reduce CO 2 emission of vehicles and create a clean energy society. This paper presents the impact of high-efficiency solar cell modules on reduction in CO 2 emission, charging cost reduction for electric vehicles, and reducing storage capacity of PV-powered electric vehicles. In this paper, the effects of solar cell module efficiency upon driving distance of PV-powered vehicles are also shown. Especially, the potential of Si tandem solar cells for PV-powered vehicle applications is discussed. This paper presents that the III-V/Si 3-junction solar cell modules with an efficiency of more than 37% have the potential of longer driving distance of 30 km/day average and more than 50 km/day on a clear day compared to an average 16 km/day driving by vehicles powered by 20% efficiency Si solar cell modules.
