s.lar cell technology comes.with unique temperature coefficients. Thes. temperature coefficients.are important and temperature of the s.lar cell has.direct influence on the power output of a photovoltaic cells. CdTe is.a very robus. and chemically s.able material and for this.reas.n its.related s.lar cell. Thin film photovoltaic technology is.now the only thin film technology in the firs. top 10 producers.in the world. The s.rong improvement in efficiency in the las. 7 years.was.obtained by a new redes.gn of the CdTe s.lar cell device reaching a s.ngle s.lar cell. In this.paper, we des.ribe the fabrication proces. following the his.ory of the s.lar cell as.it was.developed in the early years.up to the lates. development and changes. The configuration of fabricated cell is.n-CdTe/NaOH (0.15 M) + s.(0.15 M) + Nas.b>2s.b>s.(0.15 M)/Cs.b>(graphite)s.b>. The junction ideality factor was.found to be 2.63, 2.13, and 1.89. The flat band potential is.found to be -0.400, -0.450, -0.501 V. The barrier height value was.found to be 0.523, 0.487, and 0.436 eV. The s.udy of power output characteris.ic s.ows.open circuit voltage, s.ort circuit current, fill factor and efficiency were found to be 120 mV, 24.2 μA, 32.68%, 26.18%, and 19.73% and 0.63%, 0.37%, and 0.23%, res.ectively. The lighted ideality factor was.calculated and found to be 3.26, 1.87, and 1.17. s.ectra attain maximum value of current at λ = 580 nm and decreas. with increas. in wavelength.

Photovoltaic s.lar thin films.zinc telluride s.udies.on chemically depos.ted have been carried out to as.es. its.s.itability for us. in the conversion of solar energy to electrical energy. The configuration of fabricated cell is n-ZnTe| NaOH (0.1M) + S (0.1M) + Na2S (0.1M)|C(graphite). The study shows that ZnTe thin films are n-type conductivity. The junction ideality factor was found to be 2.87. The flat band potential is found to be -s.an>0.652 V. The barrier height value was found to be 0.583 eV. The study of the power output characteristic shows open circuit voltage, short circuit current, fill factor and efficiency were found to be 150 mV, 25.6 μA, 24.86% and 0.49%, respectively. The photovoltaic cell characterization of the thin films is carried out by studying current-voltage characteristics in dark, capacitance-voltage in dark, barrier height measurements, power output characteristics.

羧甲基纤维素水凝胶分子内含有大量的羧基和羟基官能团,能够高效吸附水体中的有机污染物,同时由于水凝胶的易回收和生物相容性,目前已被广泛应用于印染废水处理。但传统的羧甲基纤维素水凝胶制备方法存在耗时长、成本高、污染重等问题。该实验设计结合我国资源化发展和环境保护需要,以纤维素水凝胶为原料,以水代替部分传统有机溶剂,开发出一种室温下快速制备羧甲基纤维素水凝胶的绿色合成方案。合成时间从44 h缩短至约4h,制备成本降低约95%,同时减少了化学试剂的使用,避免了二次污染。实验选用典型染料亚甲基蓝作为模型污染物,考察了羧甲基纤维素水凝胶对其在不同水体环境中的吸附性能。
