A thick film hybrid transmitter for the radio tracking of wild animals is described. Weight considerations are of prime importance for such transmitters and the system discussed uses thick film hybrid technology, together with a solar cell power supply charging Cd–Ni batteries.To reduce power consumption a pulsed system is used; the transmitter operating frequency is in the 72 MHz band.

The non-rare-earth phosphor Ca2ZnMoO6 has a luminescence of 375–655 nm and emits near-white light. This study investigated it as a down-shifting layer to improve the efficiency of commercial flexible solar cells. The first structure was a solar cell/thick-film Ca2ZnMoO6 phosphor layer (TLDU device); a controlled light source was shone on the top, and UV light was shone on the bottom. The second structure was a solar cell/thick-film Ca2ZnMoO6 phosphor layer with an Al reflective layer (TLDR device), and only a controlled light source was used. We compared the power output efficiencies of the two structures with the efficiency of a control device. When the [Formula: see text]–[Formula: see text] properties of the three different devices were measured, the [Formula: see text] value underwent no apparent change, but the [Formula: see text] increased in the TLDU and TLDR devices. These results suggest that if placed on the bottom surface of commercial solar cells, Ca2ZnMoO6 phosphor could improve their efficiency.

Less fluorination, better performance! Devices based on DI3T-1F:PC71BM and DI3T-2F:PC71BM are fabricated for thick-film small molecule-solar cells (SMSCs). Indeed, the devices based on DI3T-1F the devices based on DI3T-1F show a better tolerance to thickness, giving PCE of 8.33% with ∼150 nm, and 5.43% with ∼300 nm, which are 14% and 50% higher than those of DI3T-2F, respectively.

<p class="AbstractEnglish"><strong>Abstract:</strong><span> </span>One necessary application of the Solar system is a water pump power supply. The solar cells typically designed solely to drive one load pump, to boost water to a high place, over one motor-pump ought to be thought of. Several completely different or similar water pumps are generated by separate solar cell sources, or the solar cells are combined for the total pump. This final project investigates once two water pumps generated by solar cells are combined, with the condition of solar radiation in Bandung. This final project analysis shows that for a special pump let alone a combined solar cell supply has a bonus. At low insulation, the pump will carry up water and may stop the flow of different pumps to enhance the performance of the opposite pump. As a solar module utilized by Arco Solar, it's the efficiency of 8.8%. Pump one efficiency of 26%, and for pump two the efficiency reaches 14%.</p><p class="AbstrakIndonesia"><strong>Abstrak: </strong>Salah satu penerapan penting dari sistem surya, adalah sebagai catu daya pompa air. Jajaran sel surya biasanya dirancang hanya untuk menggerakkan satu pompa berbeban tunggal saja, untuk menaikkan air ke tempat lebih tinggi perlu dipertimbangkan motor-pompa lebih dari satu. Beberapa pompa air yang berbeda atau sama dapat dibangkitkan oleh sumber sel surya secara terpisah atau sel suryanya digabung untuk keseluruhan pompa. Tujuan penelitian  ini adalah menganalisa bilamana 2 pompa air dibangkitkan oleh sel surya yang digabung, dengan kondisi radiasi surya di Bandung. Penelitian tugas akhir ini menunjukkan bahwa untuk pompa yang berbeda dikopel dengan sumber sel surya gabungan mempunyai keuntungan. Pada insolasi rendah, pompa tersebut sudah dapat mengangkat air dan dapat memutuskan arus pompa lain untuk meningkatkan kinerja dari pompa yang satunya lagi. Sebagai modul surya digunakan Arco Solar, berefisiensi 8,8%. Dari hasil penelitian, diperoleh untuk pompa-1 efisiensi sebesar 26%. Untuk pompa-2 perolehan efisiensi mencapai 14 %</p>

In photoelectric micro-power supply integrated on chip, the conversion efficiency of solar cell was lower compared with canonical solar cell. In order to improve the conversion efficiency of the solar cell, three technologies (fabricating back surface field, fabricating surfaces texture and reflector) were adopted in integrated process of photoelectric micro-power supply on chip. The relevant theory of the three technologies was introduced. The optimum schedule of the photoelectric micro-power supply integrated on SOI wafer was proposed. The conversion efficiency of solar cells was analyzed by simulation tools (PC1D). The results prove the conversion efficiency of solar cells was improved from 9. 34% to 13.3%.
