RESUMEN
A three-dimensional selenium solar cell with the structure of Au/Se/porous TiO2/compact TiO2/fluorine-doped tin oxide-coated glass plates was fabricated by an electrochemical deposition method of selenium, which can work for the extremely thin light absorber and the hole-conducting layer. The effect of experimental conditions, such as HCl and H2SeO3 in an electrochemical solution and TiO2 particle size of porous layers, was optimized. This kind of solar cell did not use any buffer layer between an n-type electrode (porous TiO2) and a p-type absorber layer (selenium). The crystallinity of the selenium after annealing at 200°C for 3 min in the air was significantly improved. The cells with a selenium layer deposited at concentrations of HCl = 11.5 mM and H2SeO3 = 20 mM showed the best performance, resulting in 1- to 2-nm thickness of the Se layer, short-circuit photocurrent density of 8.7 mA/cm2, open-circuit voltage of 0.65 V, fill factor of 0.53, and conversion efficiency of 3.0%.
RESUMEN
Shakuyaku-Kanzo-to was first medicated for muscular pain which was called Komuragaeri, and it has been reported that it is effective for peripheral nerve dysfunction such as arthralgia and numbness. Recently, Paclitaxel (T) and Carboplatin (J) combination chemotherapy (TJ chemotherapy) has been a standard first-line chemotherapy for epithelial ovarian carcinoma. For the arthralgia and muscular pain occurring in TJ chemotherapy, non-steroid-anti-inflammatory drugs (NSAIDs), Vitamin B12 (VB12) and Shakuyaku-Kanzo-to are the major medications. In this study, we examined twenty-one cases in which arthralgia and muscular pain occurred in TJ chemotherapy (including 16 cases as first-line chemotherapy). In all cases, patients took 7.5 g of Shakuyaku-Kanzo-to orally per day for eight days. We investigated the efficacy of Shakuyaku-Kanzo-to retrospectively with the following results. In nine cases (43%), Shakuyaku-Kanzo-to was effective in reducing pain. Especially in TJ chemotherapy as first-line chemotherapy, Shakuyaku-Kanzo-to was even more effective in reducing pain. We suggested that Paclitaxel combination chemotherapy with Shakuyaku-Kanzo-to taken orally is a more safe and tolerable way to reduce pain in epithelial ovarian carcinoma.
