“…During the past years, different substrates, deposition processes and materials were investigated by us and other groups [Plentz14,Dore13] to increase the electronic and / or optical quality of LPC silicon. In this section we first describe the deposition process and materials used for our current state of the art LPC absorbers.…”

Liquid phase crystallization of silicon (LPC-Si) offers great potential for high-quality Si films and a cost effective fabrication technique for thin crystalline silicon solar cells on glass. In this work, we report on the progress on LPC-silicon at HZB in the past years. Beginning with a brief description of the fabrication process, we summarize the work on the different contact systems developed for these absorbers before focusing on the interdigitated back contact architecture on which the highest efficiencies were reported. State-of-the art cells form the basis for a detailed discussion of the status of this technology. We investigate the current loss mechanisms and explore the potential for further improvement. Finally, based on this comprehensive quality assessment, we develop a roadmap to increase the cell efficiencies to wafer-equivalent values.

“…A variety of approaches have been developed for the production of thin crystalline silicon with thicknesses below 50 µm directly on glass substrates . One route is the direct deposition of crystalline silicon, either by epitaxial thickening of crystalline seed layers or by the usage of a high‐temperature stable intermediate substrate and subsequent bonding of the final crystalline silicon films on glass . Another route is the post‐deposition treatment of amorphous or nano‐crystalline silicon.…”

Thin crystalline silicon solar cells prepared directly on glass substrates by means of liquid-phase crystallization of the absorber utilize only a small fraction of the silicon material used by standard wafer-based silicon solar cells. The material consists of large crystal grains of up to square centimeter area and results in solar cells with open-circuit voltages of 650 mV, which is comparable with results achieved with multi-crystalline silicon wafers. We give a brief status update and present new results on the electronic interface and bulk properties. The interrelation between surface passivation and additional hydrogen plasma passivation is investigated for p-type and n-type absorbers with different doping concentrations. Internal quantum efficiency measurements from both sides on bifacial solar cells are used to extract the bulk-diffusion length and surface-recombination velocity. Finally, we compare various types of solar cell devices based on 10 μm thin crystalline silicon, where conversion efficiencies of 11-12% were achieved with p-type and n-type liquid-phase crystallized absorbers on glass.

“…Photovoltaic research started with first generation solar cells based on crystalline Si wafers 2-5 and passed through low-cost thin film solar cells as a second generation. [6][7][8][9] Now, it is heading for highly efficient and low-cost third generation solar cells. [10][11][12] To realize third generation solar cells, photovoltaic researches need to break the concept and classification of conventional photovoltaics.…”

Organic/inorganic hybrid solar cells have attracted much attention with simple fabrication and high performance because the combination of organic and inorganic materials compensates their disadvantages each other. This work tried to realize highly efficient hybrid solar cell based on crystalline Si and poly(3,4‐ethylenedioxythiophene) poly(styrenesulfonate) (PEDOT:PSS) junction. Performance dependences on the resistivity of Si substrate and the thickness of PEDOT:PSS layers were analyzed. Photocurrent of hybrid solar cells strongly depended on Si substrate, while overall performance depended on total resistance of hybrid solar cells not Si substrate. The charge transfer of PEDOT:PSS layer was varied by its thickness, and the 30‐nm‐thick PEDOT:PSS layer showed the best characteristics of charge transfer. The conductivity of the PEDOT:PSS layer was finally improved by solvent treatment using acetonitrile. As a result, the photovoltaic performance was much enhanced, and it was defined by 0.56 V of VOC, 30.24 mA/cm2 of JSC, 0.68 of FF, and 11.52% of efficiency.
