Abstract Different from the opaque conventional types, transparent solar cells (TSCs) have the great advantage of generating energy without blocking of human vision. And thus, this invisible power generator can be applied to cell phone screens, displays and windows of vehicles and buildings. The electric power conversion from UV absorption spontaneously removes the UV-induced damage on skin and eyes. All transparent solar cells were achieved by solid-state method. This dry-process ensures the long-term working device stability without any complex packaging processes of wet-type solar cells. Large-scale available sputtering was applied to deposit inorganic metal oxide layers. The sequential formation of p-NiO/n-TiO2 spontaneously forms the heterojunction and simultaneously drives the transparent photovoltaic cell. Apparently, the extension of light utilization of transparent solar cells is highly desirable to improve the performances, without scarifying transmittance at the same time. In order to tune TiO2 light response, the self-doped Ti3+ chemical state is formed which supports the transition of electrons, photo-generated by longer wavelength lights. The NiO/TiO2 TSC produces the highest photovoltage of 600 mV for UV light and also utilizes the longest wavelength of 740 nm. The TSC produced the photovoltage of 153.9 mV and photocurrent of 0.4 mA under the natural Sun light and can move a fan (0.3V and 2.5 mA) under LED light. The TSC would be an invisible power generator by supplying energy for human-electronics.

全无机金属氧化物透明太阳能电池

摘要 与不透明的传统类型不同,透明太阳能电池(TSCs)具有在不阻挡人类视线的情况下产生能量的巨大优势。因此,这种隐形发电机可以应用于手机屏幕、显示器以及车辆和建筑物的窗户。紫外线吸收产生的电能转换自发地消除了紫外线对皮肤和眼睛的伤害。所有透明太阳能电池都是通过固态方法实现的。这种干式工艺保证了器件长期工作的稳定性,无需任何复杂的湿式太阳能电池封装工艺。应用大规模可用溅射来沉积无机金属氧化物层。p-NiO/n-TiO2 的顺序形成自发形成异质结并同时驱动透明光伏电池。显然,延长透明太阳能电池的光利用率是非常需要的,以提高性能,同时又不会降低透射率。为了调整 TiO2 光响应,形成了自掺杂 Ti3+ 化学状态,它支持电子的跃迁,由较长波长的光产生。NiO/TiO2 TSC 为紫外光产生 600 mV 的最高光电压,并利用 740 nm 的最长波长。TSC在自然阳光下产生153.9 mV的光电压和0.4 mA的光电流,在LED灯下可以移动风扇(0.3V和2.5 mA)。TSC 将成为一个无形的发电机,为人类电子设备提供能量。为了调整 TiO2 光响应,形成了自掺杂 Ti3+ 化学状态,它支持电子的跃迁,由较长波长的光产生。NiO/TiO2 TSC 为紫外光产生 600 mV 的最高光电压,并利用 740 nm 的最长波长。TSC在自然阳光下产生153.9 mV的光电压和0.4 mA的光电流,在LED灯下可以移动风扇(0.3V和2.5 mA)。TSC 将成为一个无形的发电机,为人类电子设备提供能量。为了调整 TiO2 光响应,形成了自掺杂 Ti3+ 化学状态,它支持电子的跃迁,由较长波长的光产生。NiO/TiO2 TSC 为紫外光产生 600 mV 的最高光电压,并利用 740 nm 的最长波长。TSC在自然阳光下产生153.9 mV的光电压和0.4 mA的光电流,在LED灯下可以移动风扇(0.3V和2.5 mA)。TSC 将成为一个无形的发电机,为人类电子设备提供能量。TSC在自然阳光下产生153.9 mV的光电压和0.4 mA的光电流,在LED灯下可以移动风扇(0.3V和2.5 mA)。TSC 将成为一个无形的发电机,为人类电子设备提供能量。TSC在自然阳光下产生153.9 mV的光电压和0.4 mA的光电流,在LED灯下可以移动风扇(0.3V和2.5 mA)。TSC 将成为一个无形的发电机,为人类电子设备提供能量。
