“…Collecting photons on both sides of Si photoelectrode is a promising option to further improve the light utilization efficiency per unit area. [ 29 ] The photocurrent and H 2 production velocity will be further increased if the photoelectrode could collect photons from the front and back sides simultaneously. However, the Si photoelectrode with bifacial photon‐collecting ability for water splitting has rarely to be reported due to the short carrier diffusion length.…”

This paper describes a Si photoelectrode with an ultra-long minority carrier diffusion length (1940 µm) passivated by an amorphous Si layer, which provides a chemically passivated surface. With this extremely long carrier diffusion length, it is possible to separate the catalyst layer (metal) with the light absorption region on different sides of the Si photoelectrode, forming a double-side Si photoelectrode for photoelectrochemical water reduction and oxidation. The obtained photocathode exhibits a photocurrent of 39 mA cm −2 and applied bias photon-to-current efficiencies (ABPE) of 15.4% with stability up to 100 h. Meanwhile, 38.5 mA cm −2 photocurrent and ABPE of 5.8% with a 200 h stability are achieved when this structure is used as a photoanode. A monolithic unbiased artificial leaf is constructed, yielding an unbiased solar to hydrogen conversion efficiency of 3.7%. This chemically passivated Si photoelectrode breaks the trade-off between carrier transport and surface passivation in conventional Si photoelectrodes.

“…Researches demonstrated for bifacial and indoor PV that the impact of surroundings is even more pronounced on solar spectral distribution then daily, seasonal and/or weather impact. 55 Recently, it has been shown that the efficiency of bifacial PV cells 56 is bound to spectral albedo 57 and albedo itself is not only spectrally dependent but also dependent on the morphology of surrounding environment. 55 This means, even the geometry of the measurement equipment and, for indoor application, of the room might affect the bifacial cell efficiency.…”

“…The potential of bifacial photovoltaic (PV) systems over their monofacial counterpart—either fixed tilt or tracking—in terms of energy yield has been widely proved by pilot installations as well by simulations . However, the accuracy of energy yield prediction of bifacial PV systems is largely debated, which makes the bankability of bifacial technology uncertain to some extent; as a result, more experiments dealing with bifacial PV systems at various installation conditions and locations are needed to further evaluate the existing simulation models.…”

One of the prerequisites for a reliable energy yield prediction of bifacial photovoltaic (PV) systems is the capability of modeling the backside irradiance of those systems with high accuracy. Currently, the most important optical models used to quantify the reflected irradiance on the backside of a bifacial solar panel are view factor and ray tracing. The MoBiDiG simulation tool has been developed at ISC Konstanz uses the view factor (VF) concept to model the rear irradiance. In addition to the VF concept, ray tracing (RT) has been adopted to determine the backside irradiance of bifacial modules by using the open-source tool bifacial_radiance that has been developed by the National Renewable Energy Laboratory (NREL). A customized monocrystalline silicon solar panel has been built in order to evaluate the accuracy of the existing optical models by locally resolved rear irradiance measurement. The performance of rear irradiance has been investigated along the rows of the customized PV module during sunny and cloudy days with typical back irradiance values of ≈50 and ≈ 150 W∕m 2 . The comparison of measured and modeled data has been carried out on hourly, daily, and monthly basis, and the results show lower deviations for solar cells located in the center of the PV module than on the edge. Moreover, the concept of decisive solar cells has been introduced and applied to both measured and modeled data, solar cells located in the center rows were found to act as the most decisive solar cells. Finally, considering the installation configuration studied here, ie, bifacial mounting with low clearance height (below 0.2 m), both hourly RT and VF approaches are able to model long-term cumulative irradiance received by decisive solar cells with a very high accuracy ranging from ±0.5% to ±2%.
