Conversion of direct, diffuse, and albedo irradiance into electricity is demonstrated with a new kind of hybrid bifacial high‐concentration photovoltaic module named bifacial EyeCon. It consists of Fresnel lenses that concentrate the direct sunlight 321x onto III‐V triple‐junction solar cells that are mounted on the front surface of p‐PERC bifacial c‐Si cells. Thus, the Si absorbs the front and rear diffuse irradiance. Because III‐V and Si cells are electrically isolated (hence a 4‐terminal device) but thermally coupled by a dielectric adhesive, Si also acts as a heat distributing substrate. To accommodate the concentrator cells, we adapted the metallization layout and also optimized it for low intensity, ie, 200 W/m² on the front and 100 W/m² on the rear, using finite element network simulation. Additionally, when the concentrator cells are mounted on a bifacial Si cell instead of a metal heat distributor, their operating temperature is 16 K higher. However, we demonstrate with outdoor measurements that the power output of the bifacial EyeCon module reaches up to 326 W/m² when the direct to global irradiance ratio is 92%. At a lower fraction of 70% the bifacial Si cells augment the power output of the III‐V string by 19%_rel

混合双面HCPV组件的开发和室外表征

通过一种称为双面EyeCon的新型混合双面高浓度光伏组件，演示了直接，漫反射和反照率辐照转换为电的过程。它由菲涅耳透镜组成，该透镜将直接阳光321x聚集到安装在p-PERC双面c-Si电池正面上的III-V三结太阳能电池上。因此，Si吸收前后的散射辐照度。由于III-V和Si电池是电隔离的（因此使用4端子设备），但通过介电粘合剂进行热耦合，因此Si也是散热基板。为了容纳集中器电池，我们调整了金属化布局并针对低强度进行了优化，例如，正面强度为200 W / m ²，强度为100 W / m ²在后部，使用有限元网络模拟。另外，当将集中器电池安装在双面Si电池而不是金属热量分配器上时，其工作温度要高16K。但是，我们通过室外测量证明，当直接/全局辐照比为92％时，双面EyeCon模块的功率输出达到326 W / m ²。在70％的较低比例下，双面Si电池使III-V弦的功率输出增加了19％_rel
