Development of high-efficiency solar cell modules and new application fields are significant for the further development of photovoltaics (PVs) and the creation of new clean energy infrastructure based on PV. Notably, the development of PV-powered vehicle applications is desirable and very important for this end. According to the NEDO's Interim Report “PV-Powered Vehicle Strategy Committee,” a new broader PV markets with more than 10 GW and 50 GW in 2030 and 2040, respectively, are expected to be established when PV-powered vehicles are developed. Cumulative PV capacity for PV-powered vehicles will be 50 GW and 0.4 TW in 2030 and 2040, respectively. This paper presents impacts on efficiency and cost for PV-powered vehicles. According to our survey, the use of more than 30% of high-efficiency PV enables 30 km per day driving without external charging and the society that the majority of the family cars run by the sunlight and without supplying gas. Thus, we are developing high-efficiency and low-cost solar cells and modules for automobile applications. In this paper, our analytical results for the efficiency potential of various solar cells for choosing candidates of high-efficiency solar cell modules for automobile applications. This paper also presents our recent approaches: demonstration car (Toyota Prius PHV) by using Sharp's high-efficiency III-V triple-junction solar cell modules with an output power of 860 W, static low concentrator InGaP/GaAs/InGaAs triple-junction solar cell module with efficiency of 32.84%, and so forth.

开发用于光伏动力汽车应用的高效低成本太阳能电池

开发高效太阳能电池组件和新的应用领域，对于光伏（PV）的进一步发展和基于光伏的新型清洁能源基础设施的创建具有重要意义。值得注意的是，光伏动力汽车应用的开发是可取的，并且为此非常重要。根据NEDO的中期报告“PV-Powered Vehicle Strategy Committee”，预计在开发PV-动力汽车时，将在2030年和2040年建立一个新的更广阔的光伏市场，分别超过10GW和50GW。到 2030 年和 2040 年，光伏动力汽车的累计光伏容量将分别为 50 吉瓦和 0.4 太瓦。本文介绍了对光伏驱动车辆的效率和成本的影响。根据我们的调查，使用30%以上的高效光伏，每天可行驶30公里，无需外接充电，实现了大部分家庭汽车靠阳光行驶、不供气的社会。因此，我们正在开发用于汽车应用的高效、低成本太阳能电池和模块。在本文中，我们对各种太阳能电池的效率潜力进行了分析，以选择用于汽车应用的高效太阳能电池模块的候选者。本文还介绍了我们最近的方法：演示车（Toyota Prius PHV）使用夏普的高效 III-V 三结太阳能电池模块，输出功率为 860 W，静态低聚光器 InGaP/GaAs/InGaAs 三结太阳能电池组件效率为 32.84%，等等。
